Sea monsters

The coelacanth, a 400 million year old prehistoric fish once thought to be extinct, has undergone a CT scan. Forty eggs were found inside of the large, frozen bodies of the two coelacanth tested, originally caught off the coast of Tanzania and then shipped to Japan for study.

The coelacanth young are thought to hatch inside of the mother and grow to 30cm before their live birth, when they swim outside of her body, looking identical to their parents, only tiny and cute. The discovery of the eggs could contribute to evidence that the ancient ocean dweller is the missing link between fish and amphibians:

Many scientists believe that the unique characteristics of the coelacanth represent an early step in the evolution of fish to terrestrial four-legged animals like amphibians. The most striking feature of this "living fossil" is its paired lobe fins that extend away from its body like legs and move in an alternating pattern, like a trotting horse.

As far as fish go, it's just a shade prettier than the sea wolf.

Audio aquariums

Researchers at Georgia Tech are working on a system to track the motion of fish in their tank in order to make music from their movements.

[Video removed because I couldn't figure out how to turn off the annoying autoplay. Go here to watch it.]

It works through a camera that uses recognition software that tracks objects based on their shape and color. The software then links each movement to different instruments that change in pitch and tempo as the fish patrol the tank. Fish that move toward the surface have a higher pitch. The faster they move, the faster the tempo.

The idea is to create audio aquariums for the blind. (via clusterflock)
