Sea pyramid

A pyramid shaped creature that dwells at the bottom of the ocean, and emits light from its tip
== Hunting ==
When it senses prey nearby, it opens one of its four corners quickly, creating a vacuum that sucks the prey into one of its four stomachs. The sand they ingest while feeding is expulsed underneath them, slowly pushing them towards the surface. This can cause problems as it creates sand dunes harmful for ships.
These creatures have four corner “mouths” and stomachs, meaning it can feed on multiple targets at the same time (although when it feeds all four stomachs the energy required at once generally kills the beast). Sea pyramids have no perception of what is food and what is not, if it perceives anything not too small or not too big enough to fit in its mouth, it will attempt to capture it (does the sea pyramid echolocate prey?). Submarine Navy crews know well to stay very clear from sea pyramid lights as more than a submarine has been digested by a gargantuan shell.
== Growth ==
These creatures have no limit to their growth, becoming larger and larger as they age. Some sea pyramids in the abyssal depths reach tens of meters tall and 230 meters wide (50 000 m2), and are thousands of years old. Sea pyramids this size typically hunt giant squids and whales. However their own growth is a problem as their sand dune grows they theoretically reach the surface at some point and suffocate, having no adaptation to breathing air. But this is entirely theoretical
== Surfacing ==
The remains of its prey are ground up in the immensely powerful stomach acids in their stomachs and expulsed in the form of sand underneath the pyramid. This causes the sea pyramid to eventually rise, sometimes breaking the surface. 
Once, a gigantic 150M tall sea pyramid surfaces, and other races manage to enter it, carve out the flesh, and make it the center of their seagoing culture.
