Pentaceraster cumingi, sometimes known as the Panamic cushion star, Cortez starfish or knobby star (a name also used for other species), is a species of starfish in the family Oreasteridae. It is found in warmer parts of the East Pacific ( Gulf of California to northwest Peru, including offshore islands like the Galápagos) and in Hawaii. [1] In Panama this species has been collected from the Pearl Islands (depth 8 m), Gulf of Panama, and off Coiba Island, Gulf of Chiriqui. [2] It reaches a diameter of about 30 cm (12 in). [3]
Distribution and habitat
P. cumingi is found along the coasts of the Tropical Eastern Pacific [4] [5] and beyond, ranging as far north as the Gulf of California [6] and as far south as the coast of northern Peru. [4] It inhabits the shallow sub-tidal zone, usually in rocky terrain. [4]
Diet
P. cumingi primarily feeds by scavenging and through a carnivorous diet. [7] Its diet consists of ocean floor algae, microscopic organisms, and seagrass. On occasion, P. cumingi has been known to eat other echinoderms. [8]
Reproduction
P. cumingi reproduces either sexually or asexually. It is gonochoric (having separate sexes). Asexual reproduction, which results in a clonal offspring, occurs by fission, splitting the central disc. [7]
Ornamentation
The skeleton of this species is commonly used for ornamentation and sold as a souvenir in Peru and Mexico. [4] [6] The P. cumingi population has greatly decreased in Peru because of their use as souvenirs, and P. cumingi is now considered close to extinction in this country. [4] The population size in Mexico is unknown. [6]
