The Santa Cruz lava lizard (Microlophus indefatigabilis) is a species of lava lizard endemic to the Galapagos island of Santa Cruz.[2]

Description

They are identifiable by a brown body with scattered black and white blotches with a distinctive red and black throat and a black chest. Females have a more uniform brown body, a bright orange face, and a black mark at shoulder level. The species is able to shed its tail without mortal injury.[3] The

Sexual Dimorphism

Harems are kept, and are competed for by males using a pushup ritual to avoid physical injury. Males have a higher stamina and greater body size compared to the female.[4]

Distribution

Endemic to Santa Cruz Island, it is found within volcanic rock areas, dry shrublands, dry grasslands, deciduous forests, and urban areas, and prefer shaded locations.[3]

gollark: <@!309787486278909952> Please review this before I propose it.

gollark: It's not part of the rule. It's not quoted.

gollark: Does that add any problems?

gollark: I added "Due to the passage of proposal #207, bees are to be considered "deployed" initially." to the end.

gollark: I'm just going to say it's part of the state. That may mean that that rule will need to be edited, but I prefer this.
