It's Like An Echinoderm Settled Itself Into The Sand One Day And Decided "Imma Be A Cycad".

It's like an echinoderm settled itself into the sand one day and decided "Imma be a cycad".

Despite looking more like some sort of scaly tubeworm, Rhenopyrgus viviani here was actually an echinoderm, distantly related to modern starfish, brittle stars, sea urchins, crinoids, and sea cucumbers.

It was part of an extinct Paleozoic echinoderm lineage known as edrioasteroids, which lived attached to the seabed or on hard surfaces like the shells of other marine animals, using the tube feet on their five arms to catch food particles from the water around them.

Living during the Silurian, about 435 million years ago, in what is now Quebec, Canada, it stood around 3-4cm tall (1.2-1.6"), firmly anchored into the seafloor sediment by a bulbous sac-shaped base. Its long stalked body was somewhat flexible, and it was able to partially contract the top feeding region down under a “collar” of large scale-like armor plates.

...you know what? I can kind of see where the concept of feathered serpents came from.

A snake in Thailand spent enough time sitting still in the water to grow moss and turn into a dragon, apparently.

Aw yeah, anatomy!

Journey to the microcosmos is so chill and soothing.

"Pelomyxa are giant amoeba, capable of growing as much as 5 millimeters in length. So it doesn't seem like they should be that difficult to find. In fact, Jame--our master of microscopes--found hundreds of them filling up his pond tank, completely visible without the help of a microscope. They were so large that he actually took one and touched it. So, if you would like to know what it feels like to pet an amoeba, he is now an expert. He says, "It's squishy.""
