Mexico – Fish, Birds, Crabs, Marine Life, Shells and Terrestrial Life
I read in some reviews that possibly there are little lizards geckos to be found in the Playa del Carmen area in Mexico. I understand the climate is such that many types of lizards are likely to be found. If I want to avoid seeing these lizards in the room or outside it, should opting for a large hotel in Cancun instead of a resort in Playa del Carmen help? However, if you suffer from scoliodentosaurophobia fear of lizardsyou may want to consider a non-tropical environment.
Geckos are even less threatening than crabs. I've never heard of geckos doing anything that's creepy. Usually the only way you'll know they're there is when they call to each other, and unless somebody tells you, you'll probably think they're just birds. While theoretically possible, I think it is very unlikely to find one inside a resort or a hotel room. I've never had it happen. All hotels I've stayed in on the Yucatan penninsula have air conditioning, and you will not keep the window or door open for them to get in.
The standards in upscale resorts are very high and the doors and windows should be able to provide a good seal for any creatures. You are more likely to have flying creatures enter your room if you open the door at night with the inside light on, so turn off the inside light if you open the door or a window.
If by unlikely accident you find one that got in during room service, call the front desk and they will remove it. I myself would not be a happy guest if I had one inside, but I would not let it ruin my vacation.
The little lizards want to avoid seeing you, too. I hear Greenland is nice this time of year, and maybe you'd be happier there. Another full moon??? Better to put the OP'S energies into avoiding time-share "lizards" carracar. I love to see the geckos. They're small, harmless to humans, and - best of all - eat mosquitos. When they're about, you know that toxic chemicals haven't been sprayed.
Not a bad thing, IMO. When I introduced my tiny grandchildren to Mexico and they saw their first gecko, I said he was a pet and his name was Fred, but he was very shy so we had to be careful not to scare him. Now teenagers, those same grandkids welcome geckos they know they're not all named Fred! Can't say I feel the same about spiders. Wrong language but "chacun a son gout".In two vehicles we headed along paved roads and out of the city of Alamos, in Sonora, Mexico. We continued on meandering dirt roads, across a deepening river and onto a one-vehicle-wide track that had been graded from the sheer mountainside.
At each pinnacle we were provided with an eagle's-eye panorama of the city far below. On a map of these roads, what looked like a drive of less than an hour, stretched on and on for close to two hours. Dusk was upon us before we arrived at the village, valleys were already deeply shrouded in inky cloaks and the last lingering rays of the setting sun silhouetted the peaks. Stephanie, an exemplary guide, provided us with a wonderful botanical and ornithological commentary throughout the drive.
She even provided the highlights by two-way radio to the other car. The setting was picture perfect, but it wasn't quite what we hoped for. We wanted to herp, but the mountains were already becoming cold, and there were no real roads for road hunting.
Lizards in Playa del Carmen resorts?
We elected to drive back toward Alamos, hoping that once we got back to the larger dirt road that we might see some herps of interest. Of course, that meant snakes for Brad and nearly anything for me. On our way back through the mountains, we stopped at some tiny rivulet-fed ponds - puddles almost - and found a few calling Sabinal rain frogs Leptodactylus melanonotus and a pretty leopard frog Rana magnaocularis with relatively big eyes.
Once we hit the big road, a few of what we were now calling the "common frogs" - Mexican treefrogs Smilisca baudini and Great Plains narrow-mouthed toads Gastrophryne olivacea - were chorusing from roadside puddles. Just before we reached Alamos, we found one of the trip's highlights: a beautiful adult Sinaloan milksnake Lampropeltis triangulum sinaloae.
I last saw one of these magnificent tricolors nearly 40 years ago. A long hiatus, but worth the wait. There was something exciting and different about seeing this herpetocultural favorite in the wild, rather than in a hobbyist's terrarium. The Sinaloan milksnake Lampropeltis triangulum sinaloae is one of 25 subspecies of American milksnake.
Like the last few nights, amphibians were everywhere but reptiles were at a premium, at least for us. Strangely though, Young and Matt Cage were seeing one snake species right after the other. Brad and I would find frogs; the Cages would find a snake. Brad and I would find another frogs; the Cages would find another snake.
However, it was Brad's and my night to find a beaded lizard Heloderma horridum exasperatum.
And it was a pretty one, way over 2 feet in length with lots of yellow on the otherwise black-beaded scales. We almost didn't stop for the creature, as one of the intercity buses destined for Alamos had just passed and we felt certain that anything on the southside of the road was no longer alive. But you just can't drive past a beaded lizard, alive or dead.
So, downpour or not, bus or not, we stopped. When Brad hopped out to check the beast, it got up and started to walk away.
Brad blamed the paucity of reptiles on me and I on him, but the result was the same few reptiles. And it remained that way for the remaining two days. It was just one of those trips. We did see a Mexican short-tailed snake Sympholis lippiens crossing the road just as an approaching string of traffic drew near.Excerpts from Jim Conrad's Naturalist Newsletter. With my bare, high-ceilinged, stuccoed stone walls, the krrrking is loud and shocking.
I must begin a whole new cycle of going to sleep and there's a good chance that when I reach the same stage of half-sleep as before precisely the same krrrking will erupt, with the same consequences. The krrrking critters are cream colored little geckos inches long.
They climb the walls of all the buildings here and I hear them among Hotel Reef's fancy rooms. I'm guessing that that's because of the several cats there. Here we have fewer cats and more buildings. For weeks I've been wondering what gecko species I had. Unfortunately, my sleep- disturbing gecko wasn't there. A note in the general info section said that several alien gecko species have been introduced into Mexico, and the book presented only native species.
Back in Hotel Reef's computer room, by using Google's image option and the keywords "gecko, Mexico," I found pictures of my obstreperous roomy. Identification was particularly easy because where the reptile's tail attaches to his body several short, sharp but pliable spines appear. While Googling up that identification I ran across a page in Spanish listing amphibian and reptile species that have been introduced into Mexico -- Mexico's invasive species. Here I learned that my Common House Gecko is a native of islands in the Pacific Ocean, and that it's found in quite a number of places throughout Mexico.
Plus, at least two other introduced gecko species occur here in the Yucatan -- and that's atop three native Yucatec species. Ten invasive amphibian and reptile species are listed on this page, which is in chart form and thus understandable even for non Spanish speakers.
It's here. One afternoon I was glad to see this particular gecko scampering across my tile floor, for I wanted to meet the maker of all that noise. I wasn't really annoyed with him, for once you get used it -- if he doesn't call exactly as you're dozing off -- it's rather nice having such a hut mate, one who minds his own business, being so engaged in his own little life.
Therefore, to know this gecko better, I got down on my hands and knees for a better look. But as I drew near something black streaked in from the left and before my brain could register what was happening a big, blackish wolf spider had taken up position atop the gecko, and apparently at that very moment was digging his fangs into the gecko's body.
As the spider began rushing away dragging his prey beneath him I grabbed my camera and shot the image below:. In that picture one of the spider's side eyes is glowing because I used a flash, and spider eyes are very reflective.
Back when I led nighttime wildlife- watching walks in Belize, the moment during each walk eliciting the most visitor ooooohs usually came when I'd beam a strong flashlight across the rainforest floor and it'd look as if diamonds were strewn all about, those sparkles being the eyes of large spiders. Before the spider could get away I jumped around in front of him and shot a close-up of his head, seen below:.
Even in the last picture the spider carries the gecko below, though now the prey has been shifted back and isn't to be seen from the front.Unless it is geckos on the walls. I have at least two geckos. I can tell them apart because Number One is bigger than Number Two. This is my Gecko number [ This is my Gecko number one.
He was sitting on the screen of one the bedroom windows catching some morning rays. Geckos are harmless little lizards, but in the tropics, they serve a vital household chore. They kill and eat other insects. Geckos have the ability to camouflage themselves.
They can change body color to blend with their background. If you happen to touch their tail, it will instantly break off. This little trait helps them escape from their predators. Of course, they do have the remarkable ability to regrow a lost tail. Another remarkable ability of the Gecko is to walk on glass or on ceilings.
He is now traveling the world, and, in his words, is finally doing what he wants to do. Gar stops by at VagabondJourney. Gar Williams has written 65 posts on Vagabond Journey. Contact the author. Notify me of follow-up comments by email.

There are reptiles species known to live in Mexico, and it ranks second in the world after Australia in terms of reptile biodiversity. The reptiles of Mexico are unique in characteristics, color and behavioral patterns and most of them are rarely seen. The Mexican Horned Pit Viper Ophryacus undulatus is a rare and poisonous snake of the pit viper variety.
The snake is native to the mountains of southern and central Mexico. The snake has a silver-gray color and it is overlaid with a network of black dorsal blotches which come together to make a broad wavy stripe.
The top of the head is black in color and elongated supraocular scales forms two horns over the eyes.Gecko wanting his share. Mexico March 2016
The adult grows to a length of between 55 and 70 centimeters. The snake is most active during the day, and it feeds on lizards and rodents. The species is ovoviviparous reptile. The species has been listed as Vulnerable because of uncontrolled deforestation.
The remaining habitat range of the species is highly fragmented. The species is also killed when encountered by villagers. There are no specific conservation efforts targeted for the species, but it is present in at least three conservation areas.

There are also efforts to conserve the pine-oak forests where it resides, which could ensure its sustainability. The species resides in several permanent and seasonal water bodies, mostly rivers. The carapace length for the female grows to 31 centimeters while the male grows to 27 centimeters.
The species has been listed as Vulnerable due to continuing habitat loss and a narrowing habitat range. The major threats to the species' sustainability are encroaching human activities such as extensive agriculture and drying up of rivers for long periods due to the construction of dams.
Although turtles are protected from exploitation through legislation, there is absence of the primary conservation areas for this species.The common house gecko Hemidactylus frenatus not to be confused with the Mediterranean species Hemidactylus turcicus known as Mediterranean house geckois a gecko native of Southeast Asia. It is also known as the Pacific house geckothe Asian house geckowall geckohouse lizardor moon lizard. Most geckos are nocturnal, hiding during the day and foraging for insects at night.
They can be seen climbing walls of houses and other buildings in search of insects attracted to porch lights and is immediately recognisable by its characteristic chirping calls. These small geckos are non-venomous and not harmful to humans. Medium to large geckos may bite if distressed; however, their bite can pierce skin but most medium to large geckos are docile. A tropical gecko, Hemidactylus frenatus thrives in warm, humid areas where it can crawl around on rotting wood in search of the insects it eats, as well as within urban landscapes.
The animal is very adaptable and may prey on insects and spiders, displacing other gecko species which are less robust or behaviourally aggressive. The common house gecko is by no means a misnomer, displaying a clear preference for urban environments.
The synanthropic gecko displays a tendency to hunt for insects in close proximity to urban lights. The common house gecko appears to prefer areas in the light which are proximal to cracks, or places to escape. Geckos without an immediate opportunity to escape potential danger display behavioural modifications to compensate for this fact, emerging later in the night and retreating earlier in the morning.
The selection of primarily urban habitats makes available the preferred foods of the common house gecko. The bulk of the diet of the gecko is made up of invertebrates, primarily hunted around urban structures. The common house gecko is prolific through the tropics and subtropics. It is capable of existing in an ecologically analogous place with other Hemidactylus species.
Their capacity to withstand a wide range of latitudes is also partially facilitated by their capacity to enter a state of brumation during colder months. The prospect of increased climate change interacts synergistically with increased urbanisation, greatly increasing the prospective distribution of the common house gecko.
In Mexico, H. It was likely introduced through shipping and cargo. Most records of H. There is evidence to suggest that the presence of Hemidactylus frenatus has negatively impacted native gecko populations throughout tropical Asia, Central America and the Pacific. As an introduced species, they pose a threat through the potential introduction of new parasites and diseases but have potential negative impacts which extend beyond this. These differences provide H. There is also some limited evidence for cannibalism, hunting on other small Gecko species, particularly juveniles.
More aggressive and territorial males will display larger heads, with a more pronounced head shape. This increase in size is disproportionate and incurs a poorer performance in sprint time. This suggests selective pressure prioritises the competitive capacity of the male, rather than their capacity to escape quickly. On the contrary, increases in female head size are met with a proportionate increase in hind limb length and no decrease in speed.
This proportionate increase suggests that the demand on mobility from females is of greater pressure on selection. Males, instead, are selected for the capacity to compete.In Mexico they are known as gecko casero or lagartija besucona. Globally there 1, geckos of which 80 species within the Hemidactylus Genus. The Common House Gecko is a native of Southeast Asia that has been spread around the world by ships and they are now common in all coastal tropical and subtropical regions thriving in proximity to humans!
They vary in color from grey to light brown through beige with off-white undersides. They have disproportionately large heads with a long snout that is longer than the distance between the large eyes and the small roundish ear openings. The forehead is concave. The body and limbs are moderately sized. The upper surfaces of the body are covered with small granules that are largest on the snout.
The tail is rounded, slightly depressed, and covered above with very small smooth scales and a longitudinal series of six keeled tubercles. The tail is used in territorial posturing; male house geckos lift their tails and vibrate it briefly to ward off other males. The tail also provides an energy storage location which the animal uses under abnormal feeding conditions.
They have the ability to lose their tails as a defense mechanism which can be regrown. The Common House Gecko grows to They are nocturnal emerging at dusk to forage by climbing walls of houses, hotels, restaurants and other buildings that have artificial lights. They are territorial and aggressive and are known to be cannibalistic.
They are a generalist predator and will eat virtually any insect or spider they can capture and swallow. In turn, they are preyed upon by birds, cats, dogs, lizards, rats, snakes, and spiders. They are also plagued by parasites flukes, protozoans, round worms, tapeworms, and tongue worms. The Common House Gecko have life spans of about five years.
Reproduction occurs year round if temperatures are above 28 o C, via internal fertilization, with clutch sizes of two hard-shelled eggs that require 45—70 days of incubation. Eggs are placed in cavities, cracks, behind hanging pictures and other objects on walls, and in an open light sockets. In Mexico the Common House Gecko have been recorded in twenty one of the thirty one states, including Socorro Island in the Revillagigedo Archipelago; they are absent from the cooler higher elevations in southern Mexico and the interior deserts of the northern Mexico Plateau.
They are not a threat to human safety, however, they are deemed to be an environmental pest and their continued invasion within naturalized ranges is causing a significant reduction in native gecko populations especially in urban areas. The Common House Gecko has been used sparingly as a house pet. Common House Gecko, Hemidactylus frenatus.
