'Alien fish' captured off Mexico identified as rare albino shark

A bizarre-looking "alien" creature captured in waters off Mexico has been identified as a rare albino shark.

The white and pink shark was captured by a fisherman aboard Jamie Rendon's ship near Cabo last week. 

Mr Rendon said the shark had raspy skin, three rows of tiny teeth and three gill slits on each side of the head.

“I was really surprised by what caused the most impact ... the eyes [were] so strange,” he told Pisces Sportfishing Fleet.

The creature has since been identified by experts as an albino swell shark.

Thinking the "alien fish" was endangered, the fishermen went on to release the shark back into the water.

Swell sharks are harmless to humans and are known for filling their stomachs with water to enlarge their size to deter predators.
