That was a real low point for marine biogeography research

But a high point for internet mockery

But I’ve definitely been in situations where people ask “can you ID this shark species for me?” and sometimes the answer is…”Sure! Do you have photos from other angles? An interdorsal photo of its back? What about the anal fin? Any teeth pics?”

Endless slop will only make things more confusing.

To be fair, they’re almost everywhere there’s ocean, though we have some really good ones in Miami.

I think fish wisdom can appear in types of knowing that don’t rely on logic, rationality, even what we’d think of as “thought”.

Fish aren’t big overthinkers.

Oh my goodness I would be so happy if that happened.
