This is without a doubt my new favorite blog. It's hard to pick out what I like the most, but the very frank "Myth vs. Fact" post is certainly a front runner:
MYTH: Sharks have poor vision and rely on other senses.
FACT: Sharks' eyes, which are equipped to distinguish colors, employ a lens up to seven times as powerful as a human's, and some shark species can detect a light that is as much as ten times dimmer than the dimmest light the average person can see.
MYTH: Sharks must roll over on their sides to bite.
FACT: Sharks can attack from whatever direction they please. They have a unique jaw design that allows them to protrude their jaw beyond their snouts, so they can even latch on to something directly in front of them.
Via the awesome sharkblog, here's a story about some new jellyfish-like creatures that can make red light, which is totally a big deal.
