Short-spined crown-of-thorns starfish

Acanthaster brevispinus

名字的由來： The genus name Acanthaster comes from Ancient Greek words meaning spine or thorn and star, and the species name brevispinus is Latin for short spine.1

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

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

牠吃什麼？

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

怎麼認出牠

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

常被誤認為： 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

毒液力量

有毒液的棘刺

尖銳的棘刺帶著毒液。踩到或抓到牠都會很痛。

牠對人有多危險？

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

如果牠的棘刺刺到你

把傷口泡在熱水裡，水溫要在傷者能忍受、又不會燙傷的範圍內，並就醫請醫生取出棘刺。不要自己挖出來。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠的棘刺刺到：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

值得知道

小知識

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
