Characteristics

Members of the genus Olindias have a dome-shaped bell, four radial canals and many centripetal canals. The gonads are beside the radial canals and have characteristic papilliform processes. There are a few primary tentacles growing part way down the bell with adhesive suckers and cnidocytes in bands. There are a pair of statocysts adjoining the base of each primary tentacle. There are a much larger number of short marginal tentacles with rings of cnidocytes for immobilising prey. Between these tentacles there are a number of club-shaped processes which may develop into tentacles.[2]

gollark: I mean, those apply to some narrowly defined things in physics, for limited definitions of "action" and such, but not in general so far as I can tell.
gollark: I don't think so, unless you really stretch the definition most of the time or claim it's metaphorical or something.
gollark: Like "colourless green ideas sleep furiously" and such.
gollark: It's just that stuff like "thought isnt action. so things that started as thought are just concepts in action, the action is still the same action as all other actions, push and pull." and "every action has an equal and opposite reaction" don't seem like... semantically meaningful sentences. I mean, they're... valid sentences, but don't look like they're actually conveying any true useful information.
gollark: Sure?
