"Sharks have been around for a long time, emerging over 400 million years
ago. New research shows that tropical ‘walking sharks’ appeared just 9 million years ago, making them the most recently evolved shark on the planet."
“We found the sharks, which use their fins to ‘walk’ around shallow
reefs, only split off evolutionarily from their nearest common ancestor
about 9 million years ago, and have been actively [spreading] into a
complex of at least nine walking sharks ever since,”
"The giant squid (Architeuthis dux; Steenstrup, 1857) is an
enigmatic giant mollusc with a circumglobal distribution in the deep
ocean, except in the high Arctic and Antarctic waters. The elusiveness
of the species makes it difficult to study. Thus, having a genome
assembled for this deep-sea–dwelling species will allow several pending
evolutionary questions to be unlocked."
One of the most bizarre sea creatures known to science comes in many
different forms: the Siphonophore, of which there are 188 recorded
species. ROV expeditions has given the scientific community and all-new
look at the strange, somewhat creepy superorganisms which continue to
capture people's imaginations.
