The bobbit worm, also known as the sand striker or trap-jaw worm, is an ambush predator. It lives mainly in the Atlantic Ocean, but can be found in the Indo-Pacific. It hunts by hiding in soft sediment rock, and once its antennae detect prey, it emerges and grabs its prey with its sharp mandibles. It has strong grip, to the point where some prey get snapped in half! They can be anywhere between 4in to a whopping 10ft!
It can also regenerate its body from any split.

This worm is a fraud. Contrary to its name, velvet worms aren't actually worms, but actually a species of its own. There are 200 known species of Onychophora, but there could be a much higher number of them. 'Velvet worm' is just a nickname, although it's not very accurate considering they have legs. They are an ambush predator, as to catch prey, they move at a slow speed so their prey don't spot them and spray an adhesive slime. Onychophora also only hunt at night. They feed on almost any small invertebrates, including worms :(
Velvet worms are thought to locate their prey via antennae, detecting air currents caused by their prey.
