Cat Fish

All catfish, except members of Malapteruridae (electric catfish), possess a strong, hollow, bonified leading spine-like ray on their dorsal and pectoral fins. As a defense, these spines may be locked into place so that they stick outwards, which can inflict severe wounds.In several species catfish can use these fin rays to deliver a stinging protein if the fish is irritated.This venom is produced byglandular cells in the epidermal tissue covering the spines.In members of the family Plotosidae, and of the genus Heteropneustes, this protein is so strong it may hospitalize humans, those unfortunate enough to receive a sting; in Plotosus lineatus, the stings may result in death.

Sying Ray

Most stingrays have several barbed stingers (changed from dermal denticles) on the tail, which can be used exclusively in personal-defense. The stinger may possibly reach a approximately 35 cm (14 in), as well as its underside has two lines with venom glands.The stinger is covered having a slim covering of pores and skin, the integumentary sheath, in which the venom is focused.

Stingrays will not vigorously invasion mankind, even though stings do typically take place when a ray is inadvertently stepped on.To avoid moving on a stingray in shallow drinking water, the water needs to be waded via by using a shuffle.Otherwise, prior to wading, rocks might be cast into the drinking water to scare stingrays away.Experience of the stinger leads to local stress (from the lower by itselfswelling, ) and pain muscle mass pains from your venom, and then may result in disease from harmful bacteria or fungus infection.The damage is extremely painful, but seldom daily life-harmful unless the stinger pierces a crucial region.The barb generally breaks away from the injury, and surgical procedure may be needed to eliminate the fragments.

Can happen, infamously including Steve Irwin, though fatal stings are very rare. In this case, the stinger penetrated the thoracic wall surface, resulting in substantial trauma.
