Leather stars are a pacific invertebrate dwelling in waters that are typically cold. They are so named for the leathery like texture of their body. These animals 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/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, but if not completely consumed they are able to regenerate their bodies.
