I give you the Space Crawfish.
Since their hard shells are made up of the same substance as an asteroid, the Space Crawfish are hard to identify even with sensor scans.
A Federation Destoyer returning to Starbase after a border patrol is ambushed by a Space Crawfish. The Space Crawfish prefers that metals that make up the ship's hull over the minerals of the asteroids.
Luckily, two other Federation Starships are in the sector and come to the Destroyer's aid. After 8 overloaded photons, the Space Crawfish is no more.
I think this would be a cool monster to add to the ranks of the Space Manta and the others. I made up a Ship card for the Space Crawfish if SVC would like to see it.
