有毒的刺

锋利的刺带着毒液。踩到或抓住它会很疼。

它的毒液会造成什么？

Each venomous spine has several hollow, spherical capsules filled with toxin, separated by constrictions. These work like hypodermic syringes, injecting the toxin when the spines pierce the skin. The sting is painful and the pain can last several hours.1

值得了解

事实

Its venomous spines are hollow and filled with toxin, working like tiny syringes.1

Several small fish and some cephalopods shelter among its toxic spines for protection.1

Its body shell is flexible, because its plates overlap like roof tiles instead of being rigidly joined.1

Shrimps and a zebra crab live on or with the urchin, and the urchin is their host.1

Its secondary spines have sensory cells at the tip and help it move and right itself.1
