    Can anyone help identify this snake. The local calls it a Boa but I am not sure that is the case.

    The snake is between 4-5 ft and the picture is taken on the pacific coast of Nicaragua.

    How thick is it and do you have any more pictures

    Could it be a cat eyed (Leptodeira annulata)?? It's very pretty

    Yeah it looks like the cat eyed snakes. From the pictures it looks like a colubrid of some sort.

    It is a rather thin snake. about 1 inch at 4-5ft. maybe 1 1/2 inch.

    Here are some more pictures. If there is anything you want to see I can try to take a pic of that area.



    Leptodeira annulata seems to fit rather well however it seems to me that the apptern on them seldom if ever seem to go as far down towards the belly as they do on this snake. Another option that I have been playing with is a corallus annulatus allthough it might be to slender for that (see pic below) or some species of rat snake.

    Also I can add that some specimens but not all of this species rattle their tail and produce a sound when cornered. They do not have a rattle.

    I can't tell if the snake you're attempting to ID has heat pits... This character is essential for correctly IDing the mystery snake as C annulatus. I think it may be too thick to be a cat eyed species (but I could be mistaken).

    If it's lacking the heat pits I would agree that it looks like a species of rat snake.

    I do not know if the close up allow you to see anything more. It is a bit blurry.

    No I still can't see if there are heat pits.

    With respect to your earlier comment regarding the ventral striping, remember also that patterning can vary by locality and many species are polymorphic, even to a small degree. Body patterning isn't a character you can reliably use alone to ID species.

    Brown Tree Snake is my guess

    It looks like a well fed one. The thicker they are, the less severe their "arrow head" appears. They come in all different shades of browns etc. Google image them.

    Yes I agree that there are a lot of localities with different patterns but a google serach reveals none where the color extend far below half the body. However it def remains a possibility.

    I emphasized that because I've never found google to be a reliable resource for photos of the herps I've searched for.

    EYes are too small for Brown tree snake which has bigger eyes + we are in the wrong part of the world. This snake is from Central America, Nicaragua and as far as i know there are no invasive population of the brown tree snake

    It looks like a Lyre Snake
    Trimorphodon biscutatus
