Alaska Fisheries Science Center, (2007).Blood stars and other sea stars do not have a heart, centralized brain or eyes.There are over 1500 species of sea stars in the world.Sea stars can regenerate lost arms if enough of the arm remains.Predators: birds, humans Did You Know?/Fun Facts.Human collection is the main threat to the blood star.This means that they are very important for the balanced functioning of their ecosystem, and their removal could cause dramatic changes. Many asteroid species are keystone species in ecosystems.IUCN status: not listed CITES Appendix: not listed.In the Wild: sponges, plankton, bacteria At the Zoo: smelt, fish gel, squidĮdition Date – 5/10/07 Researched and written by the Friends of the Rosamond Gifford Zoo Education Volunteers Larger females discharge their eggs directly into the water and do not brood them.When the eggs hatch the young escape through pores in the skin. Smaller females brood their eggs in a depression or pouch around the mouth, which is formed by arching the arm.The breeding habits vary according to the size of the blood star.Enrichments at the Zoo: None Reproduction.The tube feet are used for many important functions, including moving around, attaching to rocks and other surfaces, and collecting food. Blood stars have a water-vascular system, a set of water-filled canals that lead to the sucker-like tube feet.They can push their stomach out through their mouth to feed. The mouth is located at the center of the underside. The trapped food is transported to the mouth with tiny moving hair-like structures called cilia. Blood stars are carnivores and eat by trapping small particles with slimy mucus on the bottoms of their arms.Lifespan: In the Wild: Unknown In Captivity: Unknown Behaviors.The eyespot is able to “see” only differences of light and dark. Blood stars have no sense organs except a red eyespot at the tip of each arm.Most sensory neurons are located at the tube feet. Sensory cells in the skin can sense light, contact and chemicals in the water.Each blood star has hundreds of these tube feet. There are two rows of sucker-tipped tube feet in the undersides of each arm. The surface of the animal is smooth and is covered with closely set, equally-sized blunt spines.The distance from the center to the tip of each arm (radius) is 3 5/8 inches.They range in color from tan and yellow to orange, red or purplish, and are usually spotted or mottled.Blood stars are sea stars and have five long, slender arms around a small central disk.Exhibit Location: USS Antiquities Characteristics.Blood stars are usually found on and under rocks that have sponges, bryozoans (tiny moss animals) or algae growing on them, and in other protected places. They occur from the low tide line and intertidal zones down to approximately 1300 feet deep. Their habitat ranges from the Aleutian Islands (west of the Alaskan peninsula) to the waters of central California. In the Wild: Blood stars are a marine species found in the coastal waters of the Pacific Ocean.Kingdom: Animalia Phylum: Echinodermata Subphylum: Stelleroidea Class: Asteroidea Order: Spinulosida Family: Echinasteridae Genus: Henricia Species: leviuscula
