Whitemouth morays ( Gymnothorax meleagris ) hide in the crevices of Indo-Pacific coral reefs with only their heads (and white mouths) emerging, mouths agape, to breathe and hunt crustaceans and fish...Read more

Like other cephalopods, the common cuttlefish ( Sepia officials ) is no dummy. But while octopuses are quick to learn manual tasks like opening jars, cuttlefish have a different skillset: the social. Unlike other cephalopod species, cuttlefish are very social and interact with each other frequently, like humans, and have sophisticated communication ability.

This guineafowl moray ( Gymnothorax meleagris ) is one of about 200 species of moray eels found in tropical and subtropical coral reefs . Moray eels are a type of bony fish. Many species, like this one with a brown body and white spots similar to a guineafowl, are named after their distinct appearances.Read more

It’s confirmed: both Antarctica and Greenland are losing ice —around 350 billion tons each year—and, as a result, sea level has risen 11.1 millimeters worldwide since 1992. This photo shows a summertime channel created by the flow of melted ice, which ultimately carries the water away from the glacier to the sea. It's not easy to measure melting ice. But by using data from 10 satellite missions,...Read more

The Trash Detectives collected hundreds of samples during the expedition, including these tiny Velella velella jellyfish larvae together with confetti-like bits of plastic. Velella velella are free-floating hydrozoans that live on the surface of the open ocean.Read more

An X-ray image of grooved razorfish ( Centriscus scutatus ). Razorfish are encased in thin, transparent bony plates attached to their spines, which you can see in the X-ray. Also known as shrimpfish, razorfish have a unique swimming style: they keep their bodies vertical (heads down, tails up) while propelling themselves forward in schools. Note that the back of the fish is bony and nearly...Read more

When coral reefs are damaged, they sometimes struggle to grow back because there aren't enough coral seedlings around, and the ones that are around are growing together too closely. Enter: the coral gardeners. Fiji's coral gardeners, who are fishermen trained by biologists, collect small corals that are struggling to grow because they have little space, and bring them to a raised platform that...Read more

Unlike the green, leafy algae we're used to seeing on the seafloor, coralline algae has a hard crust—which you can see here at the molecular level in a photo from a scanning electron microscope. Each coralline algae cell builds a limestone wall around itself, creating a honeycomb-like structure. As layer upon layer of algae grow over one another, they form an ever-thicker crust that acts as a...Read more

This rarely-seen smalleyed rabbitfish ( Hydrolagus affinis ), belonging to the order of Chimaera, was caught during a research trip to the Mid-Atlantic Ridge in 2004 sponsored by the Census of Marine Life . In Greek mythology, chimeras were beasts that were part lion, part snake and part goat, although deep sea Chimaeras are not a combination of animals. Rather, they are related to sharks, but...Read more
