Hello there. I’m here to bring a bright spot to your day with a little weird lizard, as you do.
Anolis maynardi, is endemic to Little Cayman in the Cayman Islands and introduced to Cayman Brac, and while it looks like a few of the other anoles in the carolinensis series, this one has a really long nose. It also can have striping (marbling?) along its body.
This one even has checkering!
Like the other anoles, it is capable of a dark phase. I think this is one of the better ones I’ve seen.

Its been noted that they feed on nectar like a few other anoles too. The Little Cayman Green anole has a yellow dewlap and was (hilariously) described as “…apparently stupid…” in The Herpetology of Cayman Islands (1940) by Chapman Grant.
Its elongated snout is described as pincer- or tweezer-like, and possibly aids in catching flying prey.
Like with the other anoles in this group, female Little Cayman Green anoles have smaller, more proportional heads to their bodies.
A study looking at the population of these anoles on Little Cayman and the introduced population on Cayman Brac, found that the Cayman Brac population had a higher bite force. The morphological differences between the two populations may have occurred for a few reasons. Check it out!
In collaboration with the Conservation Biology course taught by Dr. Karen Beard here at Utah State University, where I am a Ph.D. student, I have been involved in gathering life history data on ~400 species of reptiles that have been introduced outside of their native ranges for an analysis of how life history traits (e.g., diet, fecundity, longevity) interact with other factors to influence the likelihood of successful establishment. Appendix A of Fred Kraus’ 2009 book Alien Reptiles and Amphibiansis the source of the species list we are using, and included in this analysis are 26 species of Anolis. This is where you come in.
First, we coded all anoles as (i) sexually-dichromatic, (ii) diurnal, (iii) non-venomous, (iv) oviparous, (v) omnivores that lack (vi) temperature-dependent sex determination and (vii) parthenogenesis. Is anyone aware of any exceptions to these seven generalizations?
Second, we searched for data on clutch size, clutch frequency, incubation time, and longevity. The Anole Classics section of this site and the Biodiversity Heritage Library were particularly useful. After conducting what I feel to be a pretty thorough literature scavenger hunt, I am forced to conclude that some of these data simply do not exist at the species level for all of the species we’re interested in, or are not explicitly stated in a way that is obvious to a non-anole-expert. Of course, there is a lot of literature, including many books that I don’t have access to, and there are also lots of credible observations that don’t get published. I’m hoping that some of the readership here can help fill in at least some of the blanks in the table below. As one member of the team, I did not collect all of the data that are filled in myself, nor have I personally vetted every value, so if you spot an error please do point it out.
Two important points:
Many environmental factors obviously influence the life history parameters of our beloved and wonderfully plastic reptiles, so we appreciate that many of these values would be better represented by ranges and are dependent on latitude, altitude, climate, and many other factors. Where a range is published, we are using its median value.
I should also emphasize that, because of the large size of this study and the diversity of taxa included (ranging in size from giants like Burmese Pythons, Nile Crocodiles, and Aldabra Tortoises to, well, anoles and blindsnakes), it is more important for the data to reflect the relative values of these life history parameters across all anoles (and all reptiles) than it is to specifically and precisely represent all known variation within a given species of anole.
Without further ado (for your enjoyment, and because I know from my own blog that nobody reads posts lacking pictures, I’ve embedded an image of each species):

Thanks in advance. I think this is a great blog and I hope to post something more interesting on here soon.
Our A. maynardi in Little Cayman seem to be thriving. They have learned when I water the garden & have taken to either dropping out of the trees to lick waterdrops from the bushes or positioning themselves in advance. We also often see maynardi climbing up the outside of the window screen & licking the metal or licking the A/C unit..
Does the window screen taste salty too?
Licking the airconditioner, for salt? A wet-finger test showed that the surface was slightly salty. Photo by George Chaplin.
