It was probably introduced into Australia through ballast water from Japan. absence of baseline data prior to the arrival of the seastar and the presence of other In its native range, the seastar prefers water temperatures between 7 and 10oC, but can also be found in warmer waters (up to 22oC) in Australia and other countries.

Arguably, one of the most successful invaders into Australian coastal waters over the past ~30 years is the northern Pacific seastar (Asterias amurensis). Their colour on the underside is a uniform yellow. Other behaviours and adaptations The Carpet Sea Star has well-defined arms, whereas the arms of the other two common species in the area ( Patiriella exigua and P. gunnni ) are not well developed, giving these sea stars a pentagonal or hexagonal shape. 0000008472 00000 n The introduction was believed to be either as larvae through the released with discharged ballast water or by hull fouling, or other cargo ships arriving from Japan (4). endstream endobj 208 0 obj<>stream at several sites immediately beyond the current range of the seastar; (b) experiments Some pests, like the northern Pacific seastar prey on native species depleting aquaculture and fishery operations. 30 Nov 2020 The coronavirus pandemic has brought much of the world’s economies into a recession, affecting every sector of the global population. Orchitophrya invades seastars' testes, kills sperm, and castrates the seastar. directly or quantitatively in either its native or introduced range.

Free-swimming larvae of the seastar found their way into the ballast waters and since introduction, the species has massively thrown off the trophic web in the reef ecosystem. For example, the northern Pacific seastar (Asterias amurensis), a major invasive marine species in Australia, was probably first introduced to south-eastern Tasmania as larvae in ballast tanks of vessels visiting from Japan (Byrne et al., 2013).
