Sharpnose Sevengill Shark

The sharpnose sevengill shark is a small member of the cow shark family, and it is charicterized by seven gills instead of five.

Size
These sharks average 2-3 feet long, but have been recorded at 4.6 feet long at the most.

Description
This shark has a slender body (sometimes giving it the name of slender sevengill shark) and a pointed head and snout. Its mouth is small and narrow and there are seven gill slits. The eyes of the sharpnose sevengill are often large and have been observed to glow green when found in deep waters in the wild. The single dorsal fin is set far back and the upper lobe of the tail is very large compared to the body. The coloration of the back is brown or greyish, and the stomach is lighter, often with an olive tinge.

Prey
Not much is known about the diet of these sharks. They are known to eat many kinds of fish such as cutlassfish, mackeral, and javelinfish. They are nocturnal hunters, which is probably the reason for their large eyes.
