INVERTEBRATES

The warty comb jelly forms an anus only when it needs to defecate, and it may hold clues to how the anus evolved millions of years ago.

It involves something called a "love dart," and it's less romantic than it sounds.

The clever crustacean is the Houdini of the animal kingdom.

We’re talking hummingbirds, not eagles, but still.

"When I took that thing out of the tube, there was a collective gasp among the whole group, along with quite a number of expletives."

There’s evidence to support both sponges and comb jellies' claim to the title, but the latest research, published in the new journal Nature Ecology and Evolution, lands hard in favor of Team Jelly.

Tracking tags implanted in the sea stars were found lying beside the animals days later.

Scientists say the larvae flap tiny hairs to create liquid vortices that can either draw food in or help propel them through the water.

Scientists observed swarms of minuscule marine critters pollinating sea grass in the Caribbean.

Scientists say heat, not cold (or urine) is the best first aid for a sting.

"Sea cucumbers look goofy, move slowly, and barf up their guts when startled, but these invertebrates are superstar ocean cleaners that are hugely important to marine ecosystems.”

Sure, some latch on to your ankles and drink your blood, but leeches are just misunderstood parasitic worms.
