Reptile & Amphibian Forums

I have two Angel island chucks that are almost 1 year old. The larger one is 12 inches and the smaller one is about 10 inches. The larger one does a good amount of head bobbing and occasionally chases the smaller one. I'm hoping for some help in determining their sex. To me the femoral pores look small, but the larger one is somewhat aggressive like a male. Males or females?

Thanks!

Your pic tag is there but not the image.

Larger hispidus

By head shape, narrow tail base, and lack of enlarged femoral pores.

Thanks for your help. I think you are probably right about both being female.

I'm supprised to see the displays of dominance in the larger probable female. I had not observed this in the female aters that I kept previously. Maybe it's because I don't have any large males in the cage with them.

I have some real biatches! One of my female aters will charge, bite and intimidate any lizard she comes in contact with. lol I have to keep her separate from everybody. Dominance struggles happen even in female only groups. I have one redback that started being the dominant in one group before she was even half the size of the other two females that she was with. One poor girl was her fav and she would jump on her back and ride her around the enclosure! lol All of them were fat, so the chuck back rides weren't stressing the ridee out too much. All three of them have mates now.

Smaller hispidus

They both look female to me. By that age, at least in aters, the males already have chunky heads, wide tail base and noticeable femoral pores. I am not sure if it is the same with hispidus.
