Sea snakes have specialized flattened tails for swimming and have valves over their nostrils which are closed underwater. They differ from eels in that they don't have gill slits and have scales. Due to their need to breathe air, they are usually found in shallow water where they swim about the bottom feeding on fish, fish eggs and eels.

Intense pain is not obvious at the site of the sea snake bite; 30 minutes after the bite there is stiffness, muscle aches and spasm of the jaw followed by moderate to severe pain in the affected limb. There follows progressive CNS symptoms of blurred vision, drowsiness and finally respiratory paralysis.

The Moray eel’s huge head, dark eyes and concave teeth are enough to make it look menacing, yet the moray eel attacks only if it feels threatened. If it tries to bite an imprudent diver, it is only as a self-defense attack. Its bites are not venomous even if made to believe otherwise at times

But…. some species can inoculate a

toxin secreted by the buccal mucous membrane.

Lionfish, also called turkey fish, dragon fish and scorpion fish, are native to the reefs and rocky crevices of the Indo-Pacific, although they've found their way to warm ocean habitats worldwide.

A sting from a lionfish is extremely painful to humans and can cause nausea and breathing difficulties, but is rarely fatal
