This ship is probably going to suck, unless I broke a rule accidentally.

The Exo-arthropoda Magnabracchium Carcinus, also known as Space Crab, or simply Crab, is the most common member of the Magnabraquia (highly armored arthropod-like alien organisms found in the Perseus arm far from the galactic core). They're usually found hibernating for travel or consuming metals from asteroids, which are used to form their sturdy metallo-chitinous shells highly resistant to radiation. Even if they're usually peaceful, they're armed with several biological long range weapons, usually six, but sightings of eight or ten are not uncommon. It's a mystery how this trait, common to most of the exo-arthropods evolved, as competition is not strong between them.
The TSC suspects of biological engineering done by an alien intellect, something which is quite alarming considering the supposed sightings near the pleiades and the hibernating crabs found in route to them from the crab nebula. Elimination in sight is recommended, and the fortification of the outer rim of the Orion arm is already in progress.
I haven't finished this bug yet, but I guess I'll be sending it tomorrow (actually later).
