Description

The polyp grows singly from a stolon or has a few branches. It has long pedicels and medusa buds develop in clusters on branched stalks. The young medusae have very narrow subumbrellas.

The medusa has thick jelly and no peduncle. The four oral tentacles are long and branch four or five times as the medusa grows, and the oval ocelli are situated on the base of the tentacles. There are four bulbs on the margin of the umbrella with 12 to 17 tentacles on each bulb.[1]

Distribution and habitat

B. britannica is found in the north east Atlantic Ocean and the North Sea, particularly round the shores of Britain and Ireland, Belgium and the Netherlands. A record from the Mediterranean Sea is believed to be a misidentification.[1]

Biology

The B. britannica hydroid buds and forms medusae by asexual reproduction. When these mature, sexual reproduction occurs, the fertilised eggs settle out and new hydroids are formed.

gollark: Notably, English words do not actually mean the same thing as the roots might imply, in cases where there even are obvious ones.
gollark: Just because your language theoretically has words composed of subwords doesn't mean you can ignore the various problems I mentioned (except possibly the grammar one). And "convert the words to semantic expressions" hides a lot of the complexity this would involve.
gollark: I'm pretty sure I've seen diagrams of pronounceable things of some kind, but they're more complex than just permutations of "high tone, low tone" and do not conveniently map to concepts.
gollark: What do you mean "all of the possible forms of a square diagram with two or more sides"? There are infinitely many of those. And how do I just pronounce a diagram without a predetermined mapping?
gollark: Also, I have no idea what an "objective → semantic buffer" is and I think you're underestimating the difficulty of implementing whatever it is.
