Henricia sexradiata is a species of starfish in the family Echinasteridae. It is native to the western Atlantic Ocean and the Gulf of Mexico.
Henricia sexradiata is found in the tropical and semi-tropical western Atlantic Ocean. Its range extends from South Carolina to Jamaica, the Gulf of Mexico and Nicaragua. It is found on sandy and shelly bottoms at depths between 30 and 366 m (100 and 1,200 ft). [2]
Henricia sexradiata can undergo a form of asexual reproduction by undergoing fission, with part of the disc and one or more arms breaking off; the missing parts of each section then regenerate to form two new individuals. [3]
Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea. Common usage frequently finds these names being also applied to ophiuroids, which are correctly referred to as brittle stars or basket stars. Starfish are also known as asteroids due to being in the class Asteroidea. About 1,900 species of starfish occur on the seabed in all the world's oceans, from warm, tropical zones to frigid, polar regions. They are found from the intertidal zone down to abyssal depths, at 6,000 m (20,000 ft) below the surface.
The Echinasteridae are a family of starfish in the monotypic order Spinulosida. The family includes eight genera and about 133 species found on the seabed in various habitats around the world.

It is a monotypic genus and the only species is Meyenaster gelatinosus which was first described by the Prussian botanist and zoologist Franz Julius Ferdinand Meyen in 1834. It is found in the southeastern Pacific Ocean on the coasts of South America.
Echinaster luzonicus, the Luzon sea star, is a species of starfish in the family Echinasteridae, found in shallow parts of the western Indo-Pacific region. It sometimes lives symbiotically with a copepod or a comb jelly, and is prone to shed its arms, which then regenerate into new individuals.

Henricia oculata, commonly known as the bloody Henry starfish, is a species of starfish in the family Echinasteridae. It is native to northwestern Europe. It was first described as Asterias oculata by the British zoologist Thomas Pennant in 1777, later being transferred to the genus Henricia.

It is one of only three species in the order Velatida to be found in shallow water in the tropics. The young are brooded in a cavity underneath a "supradorsal" membrane.
Maureen Elizabeth Downey was an American zoologist who worked for three decades at the Smithsonian National Museum of Natural History. Known as "The Starfish Lady," she was an authority on sea stars and other echinoderms, co-founding the International Echinoderm Conference in 1972. Among her discoveries is Midgardia xandaros, the world's largest starfish.
