Etymology edit

The specific name, agassizi, is in honour of Alexander Agassiz, who was an American zoologist and mining engineer.[3]

Habitat edit

The preferred natural habitat of A. agassizi is moist rocky areas, at altitudes from sea level to 376 m (1,234 ft).[1]

Description edit

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.[4]

Ecology edit

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.[4]

Reproduction edit

A. agassizi is oviparous.[2]
