Description
Males of ''A. agassizi'' grow to snout-to-vent length (SVL), while females may reach SVL. The females and some of the males have spotted heads and grey-brown colouration. The remainder of the males have black nuptial crests, grow larger, and have larger testes. The reason for this is unknown, but may be related to the reduced predation on larger males.

Ecology
''Anolis agassizi'' is less territorial than other anoles, sharing perches and food sources without dispute. Their territories often overlap. Malpelo Island is quite barren of vegetation, and the anoles mainly eat insects, especially beetles. Based on an attraction to the colour orange, they may also eat bird eggs, as large numbers of boobies nest on the island. Their main predator is '' Diploglossus millepunctatus''.[Graham, Jeffrey B. (editor) (1975). "The Biological Investigation of Malpelo Island, Colombia". Smithsonian Contributions to Zoology Number 176. http://www.sil.si.edu/smithsoniancontributions/zoology/pdf_hi/SCTZ-0176.pdf]
Reproduction
''A. agassizi'' is oviparous
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and ...
