For those of us with a reasonable fear of the ocean, this is a worst case scenario: Last week, Dan Suski, 30, and his sister Kate Suski, 39, chartered a fishing boat in St. Lucia.

Slime Killer Hagfish Feasts in Rotten Flesh sounds like a B horror movie from the 1950s, but it's totally not: It's the title of this brand-new New Scientist article on hagfish, which might be the grossest, most disgusting-est fish in the ocean.

From Curbed Hamptons we have this aerial shot of where once stood the $43.5 million home of "billionaire hedge-funder David Tepper." Why tear down a perfectly good beach palace?

Being from New Jersey, I didn't even know waterspouts existed until today, and now, having seen this footage — captured from a helicopter by Australia's Channel 7 news — I don't think I'm ever going to go out onto the ocean again. These reportedly reached 2,000 feet, though they never touched land.

There is nothing funnier than watching people fall down. Here's a woman who falls down again and again while trying to get out of the ocean.
