The hairtail fish

Enjopy this one-minute video of a largehead hairtail (Trichiurus lepturus), the “liquid metal fish”, also called the “beltfish”.  As you can see, it’s a predator, and it’s gone some set of choppers. Its metallic color apparently camouflages it from prey. And look at that dorsal fin!

Some info from Wikipedia (their bolding):

The largehead hairtail (Trichiurus lepturus) or beltfish is a member of the cutlassfish family, Trichiuridae. This common to abundant species is found in tropical and temperate oceans throughout the world. The taxonomy is not fully resolved, and the Atlantic, East Pacific and Northwest Pacific populations are also known as Atlantic cutlassfish, Pacific cutlassfish and Japanese cutlassfish, respectively. This predatory, elongated fish supports major fisheries.

I wish they wouldn’t hold these things so long out of the water, as it makes them suffer. And I hope even more that they didn’t kill it.
