These Slimy Fish Lips Are Made for Eating Coral | National Geographic

Posted by

A new study found that one coral-eating fish has mucus-secreting lips that protects it during feeding. The tubelip wrasses (Labropsis australis) developed fleshy, protruding lips that produce a thin layer of mucus that protects them from barbed or venomous cells found on the coral’s surface. The lips allow the fish to suck edible material off coral in short “kissing” motions. Because of corals’ sharp skeletons and presence of protective surface cells, there are only a few coral-eating fish. Of the 6,000 reef fish species, only 128 feed on coral.

Attacked for Being Albino, Kids Receive Prosthetic Limbs and New Hope | National Geographic

Many people with albinism have been maimed or killed so that their body parts could be used in rituals and potions. They also face severe discrimination. But through the support of charities, these children were able to travel to the United States and received prosthetic limbs, as well as new hope.
