Large Six Gill Shark Attacks Bait Ball of Giant Octopus - stock photo

This Six-Gill shark attacks a large bait ball of giant octopus, which is their primary food source. The Six-Gill, also known as the Cow or Blunt-Nose shark are a primitive species, with its appearance similar to a fossil shark dating back to over 200 million years ago. These deep-water predators are distinguished by its unique features, having six pairs of long gill slits on each side of their broad head, yellow lower teeth, and a long tail. Their skin color is dark, ranging from grayish brown to black on the back, fading toward the lighter belly. In life the eyes are bright green, a characteristic of living in the depths of 4000 ft. of water..
