Another shark species that glows in the dark discovered



https://www.theguardian.com/science/blog/2017/dec/19/glow-in-the-dark-sharks-discovered-in-hawaii-etmopterus-lailae

If the new shark follows the pattern found in the velvet belly lantern shark, the glow is controlled two ways, by hormones and by neurotransmitters, and the effect of each can be distinguished. The shark produces the light, itself--it doesn't glow with light captured from another source, such as sunlight.

When I read of such things, the idea that the creatures were cleverly designed fits well. The idea that the several kinds of photophores each evolved by accident, from creatures that did not have them, and that the velvet belly lantern shark randomly evolved photophores with dual control mechanisms which are useful for different purposes--that seems pretty far-fetched.

I understand your thoughts, Scholar, I, too find it difficult to believe in the evolution of all living things from one primordial ectoplasm from Western Australia, of all places. Like who in their right mind would want to come from WA? :D

Still, our deepest oceans have many more surprises than we can imagine. It is still the least know area of our universe. We know more about our nearest stars than we know about our deepest oceans.
