In an effort to help us learn more about our common ancestor with the fishes, I found a quiz that tests your knowledge of modern fish.

My score - 100%
That was rather easy, wasn't it?

Puffer fish are notorious. Considerable delicacy in Japan (a taste adopted by some non-Japanese Foodies), they come with a side of risk: some puffer fish have the potent lethal toxins tetrodotoxin and/or saxitoxin, neurotoxins more than 1000 times the lethal potency of cyanide:

I'm a big fish eater. In general, given a choice about what to eat, I'm
usually happiest when I get to eat a nice fish. Even now that I've started eating
beef again, most of the time, I'd rather eat a nice piece of wild salmon
than pretty much anything made of beef.
A fascinating new study published in the Proceedings of the National Academy of Sciences suggests that the impact of human fishing may be reducing the fitness of fish populations overall.
Easy 100%. Cute quiz, anyway.
90%. I missed #2.
100% - I guessed at the one about no hemoglobin - interesting that it's the only vertebrate without it
WOW it must have been easy I scored 100%
off to see Deep Sea 3D tomorrow!
I guessed that the Ice fish would be a cold water inhabitant and that this may be related to not needing hemoglobin; 100% score.
Looked up ice fish afterwards; from http://tinyurl.com/n5mz8 :
"12/ Antarctica has a peculiar group of fish called the ice fish. These have no red pigment - haemoglobin - in their blood to carry oxygen around. Because the temperature is so low and oxygen dissolves better in cold temperatures, they get by perfectly well without it. They just have a larger volume of clear blood instead and so unusually have a ghostly white colour, particularly their gills.
These ice fish have recently been shown to have their DNA damaged by high levels of ultra violet light resulting from the ozone hole (they have less pigment to prevent the UV getting through).
Many other Antarctic sea creatures including fish have antifreeze in their blood so they don't accidentally get frozen solid!"
I got 100% but I had to call a cuttlefish a fish.
Then, I guess there is no monophyletic group 'the fishes' so maybe that's ok.
Cuttlefish??? PZ would not be happy with the disrespect given to the cephalopods.
100% here as well. I think it might have been a quiz intended for children....
I'd be up for a quiz that asked questions like:
What genus of fish are named for the character of having four teeth?
What family of fresh water fish contains the greatest number of species?
Most sessile marine invertebrates are able to photosynthesize through symbiosis with other species; what sort of species is this symbiotic relationship with?
That would be a sweet quiz.
