The Lancer Squid (Doryoforas bellatoris) is a peculiar kind of mollusk, reminiscent from the time squids still had external shells like their Ammonoid relatives. The shell of the males shell has a shield like shape with a very peculiar projection growing from it, it does not offer much in terms of hydrodynamics, but what they lack on speed, they make up for resistance and offense, as their projection can be used as a weapon. Males will often battle each other for territory and right to mate, trying to pierce each other soft parts with their shell, in an event similar to medievla jousts between knights mounted on horses, hence the name; they will also use the frontal part of their shell as a shield, often breaking the rival's spear, winning them the match, the spear will grow again in several weeks. They will also use their sharp beak and hooked tentacles to grasp and hurt their opponent as a last resort, as this puts them on risk of being hurt by their opponents weapons too.

The females are smaller and have a round snail-like shell, thought not harmless as they also have hooked tentacles and a sharlp radula, they will prefer to stay hidden in a burrow or hole in a coral reef while their male partner scouts the territory and protects her and their eggs from predators.

In the picture we can see a male specimen swimming maong biolumminescent plankton. We also see a footage of a male who just saw somethingt that got his interest (WIP).
