The jaws of the worm open like a pair of scissors to catch it's prey with the help of it's extremely sharp teeth. In some cases it cut's it's prey in two!

Their most impressive feature is their tooth, that has given them the nickname of the unicorns of the sea. The males of the species have a large spiral canine tooth that can grow up to 3 metres long, and that comes out of the left isde of their top upper lip. The true role of the tooth is unknown, but the most popular theory is that it uses it to stab it's prey of in fights with other male narwhals to attract the females. recent studies show that there are over 10 million nerve endings in the tooth, leading to the theory of it being used as a sensory organ.

promachoteuthis sulcus

The Squid with the Human Mouth - Promachoteuthis Sulcus

And yet the enviable title goes to Chaetopleura Apiculata a strange sea creaturessea mollusc that lives at the bottom of the northern Atlantic, the Gulf of Mexico and the eastern Pacific. It grows to just 25cms and eats by using it's teeth to scrape algae from the rocks at the bottom of the sea. Everyday it grows new teeth to replace the broken ones, that press down from the stomach of the mollusc. In contrast to human teeth that are made of enamel, the teeth of this mollusc are made of magnetite, the most durable material in a living organism. Scientists have used probes in order to find out more about the growth of this animal's teeth so that the can make a more resilient synthetic material in a lab environment.
