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

Leef in

Philippines, Great Barrier Reef region (Australia) and Seychelles, across a wide area of the tropics and subtropics1

Indiese Oseaan, Stille Oseaan, Koraalsee, Filippynse See

Tuis

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

Wat eet dit?

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

Hoe om dit te herken

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

Word dikwels verwar met: 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

Gifkrag

Giftige stekels

Skerp stekels dra die gif. Dit maak seer as jy daarop trap of dit gryp.

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

As sy stekels jou steek

Sit die wond in warm water, so warm as wat die persoon kan verdra sonder om te brand, en kry mediese hulp om die stekels te verwyder. Moenie self daarna grawe nie.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As sy stekels jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

die moeite werd om te weet

Feite

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
