Habitat Type: Marine
Comments: Occurs on island shores with solid rock and large lava blocks, usually at the base of tall cliffs. Often occupies caves along east shore of Guadalupe Island.
Young are born on rocky shore or in coastal cave. Shelter from direct sunlight and access to water for cooling may be important factors in selection on breeding/birthing sites (Reeves et al. 1992). Reproductive males apparently are faithful to particular breeding sites over a number of years (Reeves et al. 1992).
