The seven seas are teeming with life. The last true undiscovered country on Earth, the deepest depths of the ocean may yet hold immense lifeforms we’ve never seen. Thanks to the buoyancy water affords to those creatures that live in it, the oceans are home to the largest animals in the world.

The blue whale blows away any challengers by a large margin. Full-grown specimens can top out at upwards of 100 feet long and can weigh up to 150 tons. To give this animal’s size some perspective, its heart alone weighs an average of 1,300 pounds. That’s around the same weight as a full grown cow. What could possibly compete with that?

Well, if you prefer your gigantic water dwellers sans vertebrae, then you can always turn to the colossal squid. Best estimates put adult specimens between 40 and 45 feet long. That puts it at about half the size of a blue whale. Humpback whales should take note, though. They are about the same length, and are known to have scars that are believed to have been caused by the colossal squid.

A tad bit squishier, and a lot less deadly, is the lion’s mane jellyfish. The largest discovered was a mere 7.5 feet in diameter, but sported tentacles that measured an impressive 120 feet long. That’s longer than the blue whale up there. Despite it’s impressive size, its sting would be no more annoying than a mosquito bite to our other two seafaring giants.
