Leather stars are a pacific invertebrate dwelling in waters that are typically cold. They are named after the leathery-like texture of their body. These sea stars have a reticulated body pattern that they use to camouflage. Despite being a predator of other ocean invertebrates, leather stars make up about 50% of the diet of morning sun stars, a 10-12 armed sea star with a voracious appetite. Though leather sea stars can make a getaway of about 15 cm per minute, this is not fast enough and they are often overtaken by the morning sun star. They are also preyed upon by sea gulls and otters. If they are not completely consumed by a predator, they can regenerate their bodies.
