Cushion Sea Star
Oreaster reticulatus

Field Notes
Description:
The red cushion star is much the largest sea star found within its range, sometimes growing to about 50 centimetres (20 in) in diameter. It usually has five thick, broad arms projecting from a broad cushioned disc but some specimens have four, six or seven. The upper surface is hard and is covered with blunt spines. The colour of adults is some shade of red, orange, yellow or brown. The juveniles are greenish-brown with mottled markings.
Habitat:
The red cushion star occurs in many regions of the Western Central Atlantic, including the Bahamas, Cape Frio, Cape Hatteras, the Caribbean Sea, Florida, the Gulf of Mexico, Guyanas and Yucatán. Adults are usually found on sandy bottoms and coral rubble at depths of up to 37 metres (121 ft) while juveniles inhabit seagrass meadows where their colouring helps provide camouflage. In the winter, the red cushion star migrates to offshore locations with little water movement in order to avoid turbulence.
