While the announcer’s voice usually annoys me, I found this clip to be particularly interesting. They actually get into a nice little sidebar about the natural history of the fish that produce the eggs whale sharks like to eat. One thing I’ve always wanted to know is, why do they have the pattern of of dots and stripes on their back? Does it have a purpose? Can’t be camoflage, they are one of the biggest fish in the sea. Any ideas from our shark-savvy readership? What is the closest phylogenetic relative to the whale shark?
