For CTENOPHORE DAY, a little survey:
Which end of this fishing Pleurobrachia is the mouth on? Please just "vote" in the comments — no definitive answers. 🦑🧪🌊
P.S. this is one of my earliest #ctenophore photos, shot on film in a home-built kreisel.
P.P.S. Legit data-gathering for a future paper.

The Northern Pacific Ocean is currently smashing temperature records.
And it is reaching these levels far earlier than the current generation of climate models had expected.
