Brown Anole Eats Another Brown Anole

Photo tweeted by Sarah Knutie. Have we talked about cannibalism previously on AA? A quick search on our search bar finds two hits, one noting such tendencies in knight anoles, the other not very specific. Who’s seen it?

  1. I have personally observed cannibalistic behaviors in A. sagrei, A. carolinensis/porcatus, and A. cristatellus. On every occasion it has been a young adult male from early in the year eating a late hatchling. I have witnessed cross-species cannibalism also with A. sagrei eating A. carolinensis and A. distichus young as well as A. carolinensis eating A. sagrei young. I have not seen A. distichus eating any young or any females eating young, but that may be a factor of size.
    BTW-great photo, fantastic details. Were there 4 o’clock flowers nearby?

  2. A few years ago I saw an adult male A. sagrei jump from a tree trunk to the ground to grab up and eat a little hatchling A. sagrei. I didn’t get any photos. The adult male was a pretty good-sized anole as I remember, and the baby was tiny.

    1. Just to clarify my statement, when I stated “young adult male” I meant they were fully mature in size, but not second or third year lizards which in my observations show the identifiable traits of older lizards.

  3. A large contingent of brown anole in the yard this year, especially small ones. I questioned why the larger ones, which seem very territorial, have left them be until lately. As the days get shorter I have noticed an increase in the larger ones feasting on the younger ones. Have they left the smaller ones as feedstock as winter approach?
