I'm curious, how well do otters see at night? Do they have night vision so they can prowl in the dark?
And which otters are the most active at night?

I'm not sure, but I remember reading somewhere that they don't really use their eyes underwater, instead relying on their whiskers for sense. Which would suggest poorer eyesight in dark conditions, if true.
Also, I suspect that it is Eurasian otters that are most active at night, but that is only a suspicion.
This otter definitely sees at night, with glowing eyes like that. But I remember reading that otter's vision isn't their strongest sense, and they usually hunt with their whiskers underwater like said
I found this article where they tried to study activity patterns for neotropical otters, and this part was interesting..>The use of camera traps in two regions of Brazil, the Pantanal and the Atlantic Forest have revealed differing activity patterns in each area, this otter being diurnal in the former and nocturnal in the latterso I guess the only answer is "it depends"
