FINALLY a burst of marvellous sunshine, so time to get the garden furniture out and get a great big dose of vitamin D while changing my body hue from a slightly translucent pale
cavefish - a Farrow & Ball colour, I think - to a normal(ish) pinky colour.
In March, another group of scientists discovered Cryptotora thamicola, a type of waterfall
cavefish, in Thailand.

This percentage supports the idea that energy cost-cutting helps explain how
cavefish go blind.
Some complex systems do indeed run afoul of energy flows outside their optimality ranges, thereby devolving to simpler status of which there are many examples in Nature, and not just in biology; for example, white dwarf stars become homogenized near termination,
cavefish lose their eyesight while retreating to darker niches, and cities go bankrupt while unable to manage sufficient energy flows for their residents.
For instance, surface-dwelling progenitors of
cavefish harbour cryptic genetic variation for eye size.
In this week's edition of the journal Science, a team of researchers from Harvard Medical School and Whitehead Institute report that, at least in the case of one variety of
cavefish, that other agent of change is the heat shock protein known as HSP90.
Despite the toxic conditions, the cave harbors a diverse fauna of terrestrial and aquatic organisms (Summers Engel, 2007), including a unique population of
cavefish (cave mollies, Poecilia mexicana, Poeciliidae).
