Sea apple

Pseudocolochirus violaceus

无害对人无害。不用担心。

吃了有毒吃：小小的海洋食物碰了或吃了有毒，不注射毒液

The sea apple is a round, colourful sea cucumber that lives in the warm waters of the Indo-Pacific. It filters tiny floating food from the water with its feathery tentacles. It is special because it can release a toxin into the water when it is stressed, which can harm other sea creatures nearby.1

有毒还是有毒液？有毒液的动物通过咬或蜇注入毒液。有毒的动物是碰了或吃了会受害。这一种是碰了或吃了有害的。

它吃什么？

Sea apples feed mainly on plankton, which they filter from the water with their tentacles. They bring each tentacle to the mouth in turn and scrape off the trapped plankton.1

怎样认出它

Colourful, somewhat round body that is ovate (egg-shaped)1
A central mouth-like opening surrounded by feathery tentacles1
Rows of tube feet that help it move and hold onto surfaces1
The Australian species has a mainly purple body, red feet, and purple and white tentacles1

毒力

吃了有毒

只有被什么东西吃掉时才有害。

它的毒会造成什么？

Sea apples release a toxic saponin called holothurin into the water when they are stressed. Saponin is a chemical that is harmful to other organisms. In aquariums, this toxin can poison other animals living nearby.1

它对人有多危险？

对人的危险: 轻微像被蜜蜂蜇一下或更轻。对人基本无害。

Its toxin can poison other aquarium inhabitants, and this is one reason sea apples are not commonly kept in aquariums.1

它害怕时会做什么？

When disturbed, sea apples can violently push out their internal organs through their rear end, a process called evisceration. They can also release their toxin into the water.1

如果有人碰了或吃了它

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。
如果你碰了或吃了它：不要揉眼睛或嘴巴，洗手并就医。

它不是冲着你来的。它的毒只是为了不被吃掉。更多安全知识

值得了解

事实

Sea apples can swell to nearly double their original size by drinking large amounts of seawater when threatened or in an unsuitable environment.1

Their swollen bodies let water currents carry them to a new area, which is much quicker than walking.1

In aquariums, sea apples often starve because plankton levels are lower than they need, and they try to feed in the daytime too.1

Hermit crabs and fish often peck at sea apple tentacles, either to eat them or to steal the food caught in them.1

Sea apples usually feed at night, when their delicate tentacles are less at risk from predators.1

谣言粉碎机

谣言： Sea apples are safe for reef aquariums.

真相： Sea apples are considered reef safe for their compatibility with other species. However, they are unsafe for reef aquariums for other reasons, including starvation and the toxin they release.1
