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.
is that picture from the internet or did you take it
ReplyDeleteJorge-I took those pictures yesterday.
ReplyDeleteliar
ReplyDeleteI 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.
ReplyDeletethey look to profecinal
ReplyDeletewhen you first started working with lizards did you even mix a lizards gender? like you mistook a female for male
ReplyDeletewhich one is which?
ReplyDeleteDid you take their picture after you put them on the island or are the ones you just saw?
ReplyDeleteWhy are the female brown anole and male brown anole are different in size?
ReplyDeleteare they the same lizard?
ReplyDeleteis 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??
ReplyDeletecan a female lizard be as big as a large male lizard?
ReplyDeleteMr. Reedy!
ReplyDeleteI 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?
What other differences are between a female and male lizard?
ReplyDeletecan a female lizard be as a big as a large male lizard or as big as godzilla if there is some chemical nuclear waste?
ReplyDeleteYes you can tell the difference because the bigger one id the male and the smaller one is the female
ReplyDeletedo lizards experience birth defects due to excess uv exposure????
ReplyDeletewhat physical traits make a lizard attractive?
ReplyDeleteDoes 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?
Mr Reedy, How will the destruction of the park, from earlier, affect the the rate of catching and population of the lizards?
ReplyDeleteHow often are the females bigger than the males? Is it rare for that to happen?
ReplyDeleteWait, what do you eat? Noodles? KFC?
ReplyDeleteHmmm.....
how come the females are smaller than the males?..is there another way to tell wath sex they are?..
ReplyDeleteis there a chance the lizards will survive on the islands?
ReplyDeleteCould there be a chance that they could look similar to the male lizards?
ReplyDeleteI didn't know you were such a good photographer Mr. Reedy . :)
ReplyDeleteIs 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?
ReplyDeleteYes, 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.
ReplyDeleteThese 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.
did the lizards have any reaction when you took the pic?
ReplyDeletedoes their skin feel different?
ReplyDeleteShirley- The lizard skin feels dry and smooth. You should have touched a lizard in class!
ReplyDeleteThe 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.
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. :)
ReplyDeleteDistinguishing between male and female is one of the things we have to know for the project we are doing outside of class.
ReplyDeletewhere are these two lizards from?
ReplyDeleteI 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.
ReplyDeleteAre the females actually that much smaller than the males or is it just the pictures? If they are, are all females smaller than males?
ReplyDeleteHow do they find each other to mate and how long does it usually take for them to find each other?
ReplyDeleteAre females more viscious than males or are they equally vionent/nice?
ReplyDeleteAre the lizards in the pictures above part of the experiment or just other wild lizards?
ReplyDeleteHi All,
ReplyDeleteNathan- 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".
I think the pattern on the female is more interesting than the one on the male
ReplyDeletewhat type of camera do you use to take these amazing photos?
ReplyDeleteWhy female are more colorful than male? Do they want to attract the males?
ReplyDeleteThese are two great pictures because the lizards we dealt with in class did not have many differnt patterns.
