P'Kotman

The p'Kotmans are a species from the planet p'Kotma VII.

Biology
They look exactly like huge, bright red sea anemones. On the pocked surface of their forms, hundreds of small slots are used for communication. This species appears to have severe allergic reactions to alien sounds resulting in the need to wear full-body shields or temporary acoustic-dampening agents when traveling offworld.
