Sand strikers, also known as bobbit worms, can reach lengths of up to 10 feet. They have razor-sharp jaws that they use to capture unsuspecting fish and can split into several parts for regeneration.

As a predator, this bobbit worm will slowly prey on the fish it successfully captures, remaining undetected for years thanks to its amazing hiding abilities.

There is a common misconception that sand attackers do not have brains, but in reality, they do have brains. Although their brains are very different from the human brain, bobbit worms are equipped with cerebral ganglia, which is a cluster of cells in their autonomous nervous system.
