The sea urchin has long stood as an exemplary model for investigating embryogenesis and the intricate gene regulatory networks (GRNs) that dictate developmental processes. Studies in this field have ...

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 ...

Mushrooming carbon-dioxide levels are leading to caustic ocean conditions, but some species, like the purple sea urchin, have the ability to adapt to this changing environment, a new study shows.

Consider the sea urchin. Specifically, the painted urchin: Lytechinus pictus, a prickly Ping-Pong ball from the eastern Pacific Ocean. The species is a smaller and shorter-spined cousin of the purple ...

PASADENA, Calif.—As an animal develops from an embryo, its cells take diverse paths, eventually forming different body parts -- muscles, bones, heart. In order for each cell to know what to do during ...
