GURPS [Space] question.

[Rowan]

Hi ya. I was playing around with the alien generator tables, and I got this result:

Environment: Reef (water)
Type: Chasing Carnivore.
Movement: Immobile.


So it looked 'odd' to me obvious, then I got to thinking. Could it have very large, very very long tentacle like appendages that lie along the sea floor, and can make quick, running grabs at passing prey?

Or would that make it more like a Trapping Carnivore.

Any help sorting this out is appreciated. =)
