Fine looking female and a handsome dude.




One of the questions that you guys asked was- "How do we tell the differences between male and female lizards?"

Many of you already know if you were part of our class in the first semester because we handled so many lizards in our experiment. However, if you don't know or even if you do know and just like seeing pictures of lizards, here are two photos showing fine looking examples of both a female and a male. The female is the one with the diamond pattern on her back and the male is the larger one with the little yellow spots on his side.

  3. I think you can clearly tell the diffrence between the male and the female because the male looks more tough and bigger and the female looks small.

  12. is it in their genetic code to determine wich color,shape,and all that on its body? is it possible to breed different looking species selectively??

  13. can a female lizard be as big as a large male lizard?

    ReplyDelete
  14. Mr. Reedy!
    I can see the difference between the male anole and the female anole

    But aren't there some males anoles that are smaller and might get confused with the female anole?

  18. do lizards experience birth defects due to excess uv exposure????

    ReplyDelete
  19. what physical traits make a lizard attractive?
    Does the general color of a lizard affect the lower or higher probability of mating?
    What factors in the experiment are implented, the size or the cleverness?
    Do certain locations have greater mating then others?
    what was the longest amount it took you to obtain a lizard?
    Is there a chance that your experiment is wrong and there isn't the necassary factors for surival?

  20. Mr Reedy, How will the destruction of the park, from earlier, affect the the rate of catching and population of the lizards?

    ReplyDelete
  21. How often are the females bigger than the males? Is it rare for that to happen?

    ReplyDelete
  22. Wait, what do you eat? Noodles? KFC?
    Hmmm.....

    Is there another way to tell the difference between male and female lizards besides their size and skin pattern? And in all kinds of lizards, is male always larger than female?

    ReplyDelete
  28. Yes, there is another way to tell male from female. If you turn the lizard over and look at the area just behind the cloaca, males will almost always have 2 enlarged scales. If these are present it is a male. However it is possible ( but rare) for a male to not have these scales.

    These enlarged scales are particularly useful for determining the sex of a young male who is smaller and may appear female. There are also occasionally females who are normal female size but who have a male color pattern. These females will not have the enlarged scales.

    In nearly all lizards the male is larger but there are 4500 species of lizards so I hesitate to say all.

  29. did the lizards have any reaction when you took the pic?

    ReplyDelete
  30. does their skin feel different?

    ReplyDelete
  31. Shirley- The lizard skin feels dry and smooth. You should have touched a lizard in class!

    The lizards don't really respond when getting their picture taken. All of the close up photos on the blog were taken with a telephoto lens so we can shoot them from about 10 feet away. Also most of the good pictures were taken right after we released lizards from their bags. They tend to sit still for a few moments until they get used to their surroundings.

  32. Is there under any circumstances that you can't identify the lizard's sex? Btw you are good at taking pictures, Mr. Reedy and you are a great teacher. You love to teach and you always smile. :)

  33. Distinguishing between male and female is one of the things we have to know for the project we are doing outside of class.

    ReplyDelete
  34. where are these two lizards from?

    ReplyDelete
  35. I didn't want to touch them:[ I tend to flinch when something moves lol and btw forget the question I just asked because I didn't read your response before I asked where they were from.

    ReplyDelete
  36. Are the females actually that much smaller than the males or is it just the pictures? If they are, are all females smaller than males?

    ReplyDelete
  37. How do they find each other to mate and how long does it usually take for them to find each other?

    Are the lizards in the pictures above part of the experiment or just other wild lizards?

  40. Hi All,
    Nathan- We are pretty much always able to determine the sex if we look closely. We may have to use a magnifying glass to look for the enlarged scales, but we are able to determine the sex that way.

    Shirley- 1)The males are 3 times larger than the females by body mass.

    2) That is a great question about finding mates. In the areas were the brown anole lives the population density is usually quite high so finding mates is usually vary easy for females. It is not uncommon to find 2,3,4 or more lizards living in the same small tree. For males mate finding might be a bit more challenging than it is for females since an adult male will usually defend a territory and keep other males out.

    Cherish- Males will usually fight for territory more fiercely. We find many males with bruises, bite marks and missing tails from fighting. Females might fight less, but they also will fight with each other over territory or a prime location on a tree branch.

    Elizabeth- The lizards in the picture above are part of the experiment. I took the photos right after we released them from their bags and they were getting settled into their new homes on Island "M".

  41. where these lizards for the experiment or are they random lizards?

    ReplyDelete
  42. I think the pattern on the female is more interesting than the one on the male

    ReplyDelete
  43. what type of camera do you use to take these amazing photos?

    ReplyDelete
  44. Why female are more colorful than male? Do they want to attract the males?

    ReplyDelete

    These are two great pictures because the lizards we dealt with in class did not have many differnt patterns.
