Cow shark

Cow shark Introduction

Cow sharks are an ancient family of sharks going back to prehistoric times. They live in temperate and tropical waters around the world, and generally stay in deep oceans. For this reason, scientists don’t know a lot about them, and only recently discovered a new species.

The sevengill cow shark is sometimes fished for its meat, leather, and oil. It’s also sometimes caught in fishing nets meant for other fish.

Cow sharks are generally not dangerous unless they’re provoked. They will flail, lash, and bite fishermen when caught—but you can hardly blame them.
