Description

Hydrozoans with dome-shaped bells and tentacles set above the undulating margin of the bell. There are gastric pouches containing the gonads situated between the tentacles, the number of pouches being greater than the number of tentacles. The pouches extend below the points of origin of the primary tentacles. Some genera have a peripheral canal system and others do not, and some have secondary tentacles.[2]

gollark: I do wish the internetworking companies would just use some sort of scheme of limited bandwidth with some allowance for short peaks instead of data caps, which would match closer to what the actual constraints are.
gollark: Though over here they're mostly just used on mobile phone connections, not home ones.
gollark: Data caps do kind of work well at getting people to use less *bandwidth* because people don't use their internet connection as much, but they don't actually have some finite amount of internets or something weird like that.
gollark: Though you do need sensible small parties in the first place.
gollark: Probably less so, if you can vote for a popular party you like less and a less popular one you like more. It reduces the "I don't like either big party but I'm voting for the least bad one" thing.
