Krackaen: The Galactica Navy's Backbone
It is surely a coincident that the Galactica Navy's Backbone- or as one of their nicknames goes- is a species of invertabraes- or spineless creatures. The Krackeans are the backbone of the Galactica Navy, and have been ever since their first contact with humans during their more colonial days circa 2378.

They are unique in the crustacean-like classification, due to many things, but are nonetheless the backbone of our great navy. They helped in the First Galactic War against the Rissoni, where the great Admiral Chozo led his forces to victory in the first battle, now known as Chozo's Run due to it actually being a route his forces took to escape Rissoni craft. He was also the first Admiral to led his men out of the Rissoni's clutches in safety, something that made him his spot in Galactica History.
