The Dickkopfanolis ( Audantia cybotes , Syn . : Anolis cybotes ) is a lizard species from the group of the iguanas . It is native to some of the Caribbean islands that make up the Dominican Republic and Haiti .
description
The males reach a maximum size of 18 to 20.3 cm, the females are slightly smaller. The color is brownish, never completely green. The males often have greenish or dark brown stripes on the body, legs and tail. The throat flag is yellowish, sometimes with an orange spot. The female is orange-brownish with a light stripe on the back from the head to the tail. The body temperature changes because the anole species, like all reptiles, belong to the cold-blooded animals and are dependent on the temperatures in their environment. During the day, their body temperature near the ground can rise to an average of more than 30 ° C.
Distribution and way of life
The thick-headed anole is found on the Caribbean islands of Hispaniola , Île à Vache , Île de la Tortue (Tortuga), Isla Catalina , Isla Saona , Isla Catalinita , Île Grande Cayemite , Île de la Gonâve , Île á Cabrit , as well as in Florida and Suriname , spread. It often occurs together with other anole species in the same biotope, sometimes hybrids occur .
The animals live on the edge of the forest, rarely in the dense forest, rather near the ground. You can stay in one position for a long time and then quickly change position. They are rather mediocre climbers compared to other anoles. The thick-headed ankle feeds on dragonflies , cockroaches and puffer-finger geckos .
Systematics
Subspecies
Three subspecies have been described so far. This radiation can be explained by the isolation on different islands .
- Audantia cybotes cybotes lives on the island of Hispaniola and some smaller, offshore islands, but not on the Isla Saona and the Île de la Gonâve, where they are each represented by one of the other two subspecies.
- Audantia cybotes doris Barbour, 1925, is native to the Île de la Gonâve.
- Audantia cybotes ravifaux Schwartz and Henderson, 1982, occurs on Isla Saona and - not entirely certain - on Isla Catalinita.
