| Celtic Ferret |
I went to the Columbus Zoo today as part of a larger group of rescues. HOFA
did education/ferret awareness. There were 6 of us there. People mostly
came in waves.
We took our lunch break first. We were told to go see one or both of the
otter displays. The American river otter and the Chinese otter. We got
lunch and then went to see the river otter.
Otters deserve their reputation as clowns and entertainers. You'd sweat
they knew when someone wanted them to pose for a pic.
I think we watched them for 10 to 15 minutes. They were so elegant in the
water. Prettier than my mink. Mink push off to swim to get up speed, we
saw the otters do the same thing.
I haven't checked yet. Mink have a double retina, one for on land and one
for underwater vision. I can't help but wonder if otters eyes are
structured the same way. This is an obscure enough question it probably
won't turn up on the net.
We got back to our ferret awareness day.
I saw a puppy that reminded me of a dog I had when I was 20. It was adopted
out and I hope went to a good home. We've decided no more dogs, since ours
died earlier this year. I saw lots of cats, but Dan is allergic to them.
I'll have to stick to my ferrets, mink and skunk.

Is what you're referring to the tapetum lucidum? It's the thing cats have
that makes their eyes flash in the dark when light hits them. Dolphins have
it as well as sea otters, if that's the "double retina" you're referring to.

I have to guess your refering to the "clear" second eye lid. Ferrets have
this, mink have it, and I *assume* otter do as well. Mink actually have two
seperate retinas, one for under water and one for land. I haven't checked
yet, but *assume* otters do too.
Mink and otters are clearly seperate species, but they share a number of
structuarl characteristics.
Even mink and ferrets have the same foot, ferrets have dog type claws and
mink have cat like claws.

PS My info on the mink comes from The Mink by Nigel Dunstone.
