The short-spined crown-of-thorns starfish is a large, spiny sea star that lives on the sea floor in parts of the western Pacific and western Indian Ocean. It belongs to a genus with only two species, and it is less well known than its relative, the common crown-of-thorns starfish. Its many arms and dense spines make it easy to tell apart from typical starfish.1

首页

It has been found at moderate depths, from 18 m to 63 m. All known specimens came from soft sandy sea floor rather than hard coral reef. The Great Barrier Reef specimens were caught as unwanted bycatch by trawl nets off Townsville.1

它吃什么？

Scallops appear to be an important part of its diet. It creeps up on a scallop over the hinge, where it is less visible, and traps the scallop under its disc. Laboratory observations also show that it eats a wider range of food.1

怎样认出它

Dense, blunt spines cover the upper surface of its central disc.1
The upper surface is purple-brown and gets darker towards the arms.1
Darker blotches run around the edge of the disc and along the arms, with a large blotch at the base of each arm.1
Pale marks sit on the disc between each arm.1
Its arm spines are shorter than those of the common crown-of-thorns starfish.1

常被误认为： It is most often confused with the common crown-of-thorns starfish, Acanthaster planci. The short-spined species has blunt spines on its upper surface, short pedicellaria (tiny pincer-like structures), pale marks between the arms and shorter arm spines. The common species has longer arm spines and lacks the pale marks.1

毒液之力

有毒的刺

锋利的刺带着毒液。踩到或抓住它会很疼。

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

如果它的刺扎到你

把伤口泡在热水里，水温以不烫伤为限、尽量热，然后去看医生取出刺。不要自己去挖。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果它的刺扎到你：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

值得了解

事实

It catches scallops, which are fast swimmers, by sneaking up on them and trapping them under its body.1

It has many arms rather than the usual five, so it has lost the five-fold symmetry typical of starfish, although it starts life with five-fold symmetry.1

Its feeding posture, with the body arched over the prey, is so distinct that even the taste of scallop meat triggers it.1

In a 1973 laboratory experiment, it was crossed with the common crown-of-thorns starfish, and the hybrids reached sexual maturity at the end of their second year.1
