This species, known as the bobbit worm (Eunice aphroditois), is a carnivorous worm that usually makes it home by digging a vertical burrow in the sand between rocks or corals in a tropical reef. The burrow is barely wider than the creature's body, but must be as deep as the worm is long. The bobbit worm finds prey with five long antennae on the top of its "head". These antennae wave in the current, picking up scents of possible prey in the water as they flow by and letting the worm know a meal might be near. Not only does it strike at its prey with sharpened jaws, it injects a toxin, which stuns or kills it. The worm can grow up to ten feet in length and eats mostly crustaceans and mollusks.

The Dana octopus squid (Taningia danae) of the Pacific blinds its prey with flashes of light from its arms! It is believed that this highly maneuverable squid uses the bright flashes to disorientate potential prey. These flashes may also serve to illuminate the prey to make for easier capture as well as a courtship and territorial display.

The relative speed is based on body length. The tiger beetle (Cicindela hudsoni) run so fast, their eyes can’t process information as quickly as they need to and they temporarily blind themselves. Some sources claim that the tiger beetle can up to 9 km/hour!

When attacking prey, the beetle will aim itself at its target and start running, but will need to stop and relocate the prey because it cannot keep an eye on it. Once it has reoriented itself, it charges forward again and hopes to run into the target. ...
