Friday's decisions move whale sharks, manta rays and devil rays onto Appendix I after countries on Thursday did the same for the critically endangered oceanic whitetip shark.

Perhaps the manta ray-looking underwater vessel was being tested in their backyard?

A team of researchers has beaten its own record for the fastest swimming soft robot, drawing inspiration from manta rays to improve their ability to control the robot's movement in the water.

"We want to expand the design space of traditional cross-flow filtration with new knowledge from the manta ray," says lead author and MIT postdoc Xinyu Mao PhD '24.

Coral reefs that some marine biologists call the Amazon of the ocean lie just offshore, home to giant clams, nurturing small fish, which in turn are prey for manta rays.
