Shrimp

Found near water, the Shrimp are mutated crustaceans, with armoured carapaces and extremely territorial aggressive behaviour. The Females of the species are often found in the water and tend to roam in packs. When threatened, they will attack from a distance, spitting corrosive mucus to incapacitate their target. The Males, who tend to live solitary lives, have additional armoured plates on the fore legs. These limbs are used as clubs when attacking and double as shields for defence. You'll need to time your attacks perfectly to defeat him.
