Asterias amurensis, also known as the Northern Pacific seastar and Japanese common starfish, is a seastar found in shallow seas and estuaries, native to the coasts of northern China, Korea, far eastern Russia, Japan, Alaska, the Aleutian Islands and British Columbia in Canada.
The Northern Pacific seastar is considered a serious pest of native marine organisms in Australia, and is a major factor in the decline of the critically endangered spotted handfish. It preys on the handfish eggs, and/or on the sea squirts (ascidians) [1] that help to form the substrate that the fish spawn on. [2]
Asterias is a genus of the Asteriidae family of sea stars.It includes several of the best-known species of sea stars, including the common starfish, Asterias rubens, and the northern Pacific seastar, Asterias amurensis.
Little is known regarding their diet, but they have been known to prey on small shellfish, shrimp, and polychaete worms in the wild. When captive in aquaria, spotted handfish eat mysid shrimp, amphipods, and small live fish. Newly hatched handfish have been observed to do quite well on a diet of small amphipods. [8]
They occur predominantly on deep-water continental shelf habitats (but a part of them inhabit shallow waters) [3] in all the world's oceans, being the most diverse in the Indo-Pacific region. [ 4 ] List of genera
The orange sun star is found in the northern Pacific Ocean, its range extending from Japan and the Bering Sea and along the North American coast as far south as California. With a depth range of between 11 and 3,740 metres (36 and 12,270 ft), it occurs at greater depths than any other starfish in the north west Pacific.
