It’s been a big month for developments in transparency.
First: the Antarctic icefish, whose native habitat is 3,200 feet deep in the waters off the coast of Antarctica. Earlier this month, Tokyo Sea Life Park debuted its display of the only captive icefish in the world, prompting a flurry of news pieces about the fishes' mysterious clear blood. The aquarium boasts they now have a mating pair of icefish, which could enable studies on their unique cardiovascular system in a controlled environment.
