It clearly shows why you should not step on a stone fish

If a person steps on a stone fish or accidentally touches it, it will immediately plunge into him the spines of its fins, at the base of which there are poisonous glands. Wart poison is extremely dangerous. Having been pricked on the fins of a stone fish, a person first experiences a burning pain at the injection site.

Against the background of pain, traumatic shock develops very quickly, and then paralysis is possible if the poison reaches the nerve endings. Tissue death is observed at the injection site.
