A gull raises a foot as it slurps up some orange uni from a busted open sea urchin.

A younger gull, eyes still brown, hold up a busted sea urchin in its bill, tongue ready to lick up some good stuff.

No bird brain! This Herring Gull flew a semicircle around the wharf, turned back gaining altitude and dropped a sea urchin onto the concrete deck. Soon joined by a second, younger gull.

Brain-like features in sea urchin larvae reveal light-dependent behavior Researchers at University of Tsukuba identified a brain-like cluster of neurons in sea urchin larvae, traditionally considered lacking a brain, that regulates light-responsive behavior. These neurons possess a subset of gene expression profiles similar to those found in vertebrate brains, offering new insights into the evolutionary origins of brain functions that may trace back to a common ancestor in the bilaterian lineage of animals.

Green sea urchin viewed from underneath on glass. Tube feet are visible and a white bit of goo is in the middle of the urchin's body. That is the food.

Slightly closer view of photo 1

Close up of the white goo scallop being held by the sea urchin's tube feet.

A green sea urchin having a little snack.

The mouth of the urchin is on the underside of the body. It has used its tube feet to pass the piece of scallop (the white goo) from the side of the body to the mouth underneath.

🪨Sea urchins can be spotted carrying around objects, like rocks and shells!🐚

🤔Some theories for this put it down to camouflage from predators🐟, or protection from the sun's UV rays☀️

❤️ Sea Urchin Fossil we found two days ago at North Myrtle Beach, SC. It's as hard as a rock. They say it takes millions of years for this to occur. They're not worth much money, but a cool find nonetheless.
