The goblin shark ( Mitsukurina owstoni ) is one of the creepier fish out there! It has a long, prominent snout covered with special sensing organs (ampullae of Lorenzini) that help it to sense...
The distinctive form of a winghead shark ( Eusphyra blochii ) is revealed by an X-ray image. The Winghead Shark, one of about ten species of hammerhead sharks, has its eyes set at the tips of its...
Researchers from the SOCAL-10 research partnership study the behavior of orcas (commonly called killer whales) and how they react to sonar and other noisy human activities. The partnership is...
A great white shark ( Carcharodon carcharias ) emerges from the water's surface, gaping at the photographer. Gaping is a way sharks communicate with each other, and maybe even try and communicate...

The yellow features in this 3-D reconstruction of a fin whale fetal skull represent the early developmental stages of ear bones, characteristics that are extremely rare, fragile and nearly impossible...
Sharks have six highly refined senses: smell, hearing, touch, taste, sight, and electromagnetism. These finely honed senses, along with a sleek, torpedo-shaped body, make most sharks highly skilled...
Great white sharks ( Carcharodon carcharias ) are marvels of evolution, with highly-evolved senses keeping them among the ocean’s top predators. However, they are threatened with extinction and...

Sharks are much older than dinosaurs. Their ancestry dates back more than 400 million years, and they are one of evolution’s greatest success stories. These animals are uniquely adapted to their...
These Themisto hyperiids live in the top 200 meters of cold waters around the world. Each of their two large eyes has an upward-looking zone and a downward-looking zone. Each zone can see at...
Under white light, this shortnose greeneye fish ( Chlorophthalmus agassizi ) looks unimpressive. But, in dim blue light—the type usually seen at depth—it shows its true fluorescent colors. NOAA...
This is another view of Phromina from the side. The eyes take up most of the head, with one pair looking to the side (the red spot) and one pair facing upwards. Phronima live anywhere from 200-1100...
Ships are well-known for their tiny rooms and tight quarters. But have you heard of a sea vessel that has toilets and sinks sticking out of the walls, and staircases and doors on the ceiling? This...
