Description

The Norway bullhead is a small fish that only grows to 7.4 cm in length. It has a row of bony knobs above the rough lateral line.

It feeds on small crustaceans (amphipods, decapods) and fishes. It spawns in early spring, laying demersal eggs, in clumps on bottom, diameter 2 mm. Larvae are pelagic. A population of Norway bullhead is capable of doubling its numbers in under fifteen months.

Habitat

It is found on hard sea bottoms (gravel or shells) or among seaweeds, in cold areas – even with temperatures below 0 °C. It feeds on small fish, amphipods and other crustaceans.

gollark: That's... surprisingly expensive actually, how high-traffic *is* this bot?
gollark: I mean, if you have something else to talk abut, I don't think anyone will stop you?

gollark: Not really. I mean, they're expecting to just magically moderate stuff outside the subreddit or servers they control (which I strongly disagree with), and did not explain how the possibility of fake screenshots or whatever could be handled.
gollark: The whole "trust us it will be enforced sanely even though we won't explain ~~why~~ how" thing, centralizing meme picking power...
