Bioplasmic organism

A bioplasmic organism is a type of large, space-dwelling lifeform.

The largest bioplasmic organism known was encountered by the USS Voyager in 2375. It attracted starships into its digestive tract by telepathically granting their crews their greatest desires, and then consumed them. For the Voyager crew, this took the form of a wormhole leading to Earth. Seven of Nine discovered the organism's true nature and engineered Voyager's escape with the help of Qatai, who had dedicated himself to destroying the creature. It was dubbed the telepathic pitcher plant. 

Bevvox, founder of the Think Tank, was a bioplasmic organism.
