The hydroid paper
A young Bouillonia cornucopia I woke up to a nice surprise today: the paper I wrote about the Arctic deep-sea hydroid Bouillonia cornucopia has been published online! You can find it here in the journal Invertebrate Biology . This paper has taken shape over the past couple of years. I first started noticing B. cornucopia in the Arctic in 2017 . After that, I collected samples opportunistically from moorings until I had a couple hundred individuals. Very little is published on B. cornucopia because it's so rare, so I was able to learn a lot from my samples - how the species reproduces , where it settles, how it grows.

Sometimes, it can settle on other animals, for example on the legs of a crab, but when an artificial habitat like a mooring shows up in the water, it goes nuts! It grows quickly and reproduces like mad. For decades, scien
