Pretty little polychaetes who bury their several-metre-long bodies in the ground and wait until something brushes up against one of their antennae. They then snap their venomous mandibles shut so fast they sometimes scissor their prey right in half
Most plankton are tiny drifters, wandering in a vast ocean. But where wind and currents converge they become part of a grander story… an explosion of vitality that affects all life on Earth, including our own. Watch the latest “Deep Look” video from KQED and pbsdigitalstudios:
The hyrax is a herbivorous animal native to Africa and the Middle East. Often mistaken for rodents, they are more closely related to elephants and manatees. There are four different recognized species of hyrax.
(If you think these little guys are adorable, I highly recommend going to the wikipedia page and watching the short video of a hyrax chewing. You will not be disappointed.)

Your Shot photographer Ponnie J. found this octopus “hiding under a [discarded] bottle” in the waters off Pattaya, Thailand. The cephalopod appears to wish to remain unnoticed. Having no body armor, octopuses are masters of hiding and disguise. Find out more about how octopuses use their wits to survive in the November feature article “Why Do Octopuses Remind Us So Much of Ourselves?”

Nautiluses are super cool!! They’re the oldest living subclass of the cephalopods, and really haven’t changed all that much since the late triassic! Their ancestors were called ammonites which appeared waayyyy back in the devonian period (419.2–358.9 million years ago). I had a whole post on ammonites a long time ago which you can find here: http://squidscientistas.tumblr.com/post/124712468719/firstly-you-guys-are-awesome-and-i-love-this
Nautilus shells are composed is many gas chambers and as it gets bigger the nautilus will close off one of the chambers and move its body into the next one.
