Squidsnails can be encountered almost everywhere in the galaxy, since they don't have to breathe and can use their incredible brain to convert light into energy, and their tentacles to swim in the outer space. They can move on any surface, including vertical ones and ceilings, at their usual speed. They're always hungry. Squidsnails are quite intelligent: they never engage on a combat unless sure to have good possibilities, and rarely fight until death. If encountered in small groups, they are able to plan their attacks and ambush the victims. Squidsnails comes with various size:

Size	Hit Dice	Dmg per Tentacle
Medium	5+3	1-8
Large	6+3	1-10
Giant	7+3	2-20
Mastodontic	8+3	3-30
Gargantuan	9+3	4-40
Nightmare	10+3	5-50

Nightmare sized Squidsnails are big enough to attack transport spaceships, destroy them and eat the crew. Kinda like Twenty Thousands Leagues Under the Sea, you know.
