Like this ctenophore ( Aulococtena acuminata ), many animals that live in the midwater zone are red—making them almost invisible in the dim blue light that filters down from the sea surface. This...
The ocean covers more than 70 percent of the Earth and is essential to all life. But forces of change, from overfishing to climate change, are affecting the ocean and humanity's relationship with it...
