– Sea otters hold hands in their sleep to avoid drifting away from each other.
– Manta Rays can have a wingspan of over 30ft.
– The top predator of the ocean, is in fact, the Killer Whale (orca), not the Great White Shark.
– U.S. research from the 1980s estimated a 66-pound meal of mammal blubber could sustain a one-ton Great White shark for more than six weeks. That gave way to assumptions that large sharks could survive long periods without eating. However, a University of Tasmania-led study published this week in Scientific Reports on the nature.com website found that 30 kilos was only enough for 12-15 days. (News.discover.com)
