Mechanical Water Mines were a common enemy in the first underwater stage depicted in a Castlevania game, which was in the NES parody game Akumajō Special: Boku Dracula-kun. These water mines were later re-imagined as spiky sea urchin enemies, making their first appearance in the underwater areas of Castlevania: Aria of Sorrow, where they were given the name Needles.
They were mostly stationary, though they bobbed up and down slightly. When attacked, they exploded sending shrapnel in a radial pattern.
These enemies can't move, and for the most part they serve only as obstacles. Its soul gives Soma the ability to place similar urchin mines in mid-air, which will explode upon contact.
In Order of Ecclesia the Needles appear on the surface of the ocean in Kalidus Channel and Somnus Reef. They can also appear underwater and sometimes they can drop Salt, which is the item required to complete Aeon's quest "Needs More Salt".
