The branch of zoology that is concerned with the study of fish. This includes bony fish (Osteichthyes), cartilaginous fish (Chondrichthyes) and the jawless fish (Agnatha).

FishBase (an online database of fish) suggests that there are 31,900 species of fish currently known to science, although other sources suggest more, and the total is still increasing as we learn more about the oceans. And fish are fascinating.

Emperor Akihito of Japan is a reknowned ichthyologist.

This gorgeous creature is a leafy sea dragon (Phycodurus eques), from the same family as seahorses. They are found only in the waters of Southwestern Australia, perferring sandy areas up to around 50m deep.

The leafy protrusions from its body are for camouflage, allowing individuals to blend into seaweed on the sea bed. Leafy sea dragons reach around 20cm in length, and like in seahorses, the male will incubate the eggs.

Wow, that's a cool-looking critter :D.
But don't you watch QI? There's no such thing as a fish ;).

According to Q.I., there is no such thing as a fish. So there cannot possibly be any such thing as icthyology.

There may not be any such thing as God either, but there are still departments of universities that study theology.

There may not be any such thing as society either, but there are still departments of universities that study sociology.
