Etymology
The specific name, agassizi, is in honour of Alexander Agassiz, who was an American zoologist and mining engineer.[2]
Description
Males of A. agassizi grow to 89–114 mm (3.5–4.5 in) snout-to-vent length (SVL), while females may reach 79–84 mm (3.1–3.3 in) 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.[3]
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.[3]
