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 ...

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.

Marine biologists at Scripps Institution of Oceanography at UC San Diego have created a line of sea urchins whose genetic makeup is fully mapped and can be edited to study human disease genes. The ...

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 ...

Ravenous, brainless and covered with spikes, sea urchins have evolved to not be messed with. Off of the south coast of Oregon, one kind of urchin in particular, the purple sea urchin, is enjoying an ...

Sea urchin larvae raised in high levels of plastic pollution die due to developmental abnormalities, new research shows. Scientists put fertilised urchin eggs in seawater with varying levels of ...

The loss of one iconic species, sunflower sea stars, unleashed a voracious eater of seagrass habitats and upended the coastal ...
