The three-spot frogfish ( Lophiocharon trisignatus ), seen here off the coast of Western Australia, looks like it might just be a rock or a part of the sea floor! Frogfish use various methods of camouflage such as their rough shape, color changes and even inflation to hide from their predators. The male of this species carries clusters of eggs on its side while they develop.Read more

Gray reef sharks ( Carcharhinus amblyrhynchos ) are known for being active at night. They are considered Near Threatened by the IUCN Red List due to fishing and the loss of their coral reef habitat. The sinister animal, with its sleek body, can be quite aggressive when directly threatened. “It was shaping up to be a bad night dive when my mask broke and I was forced to come up early. The others...Read more

There are over 30 colonies of king penguins ( Aptenodytes patagonicus ) on South Georgia Island in the Southern Atlantic Ocean. The penguins capture their prey, typically lanternfish, by diving at speeds of 12 miles per hour. “This photo was taken the first evening of six that I spent at South Georgia Island. It captures a group of penguins on their way to the ocean to feed. As they approached, I...Read more

Tectitethya crypta (formerly known as Cryptotheca crypta ) is a large, shallow-water sponge found in the Caribbean. It was first studied for medical purposes in the 1950s when few scientists or doctors thought to look for medicines in the ocean. But in the sponge, scientists isolated two chemicals — aptly named spongothymidine and spongouridine — which were used as models for the development of a...Read more

Weedy seadragons ( Phyllopteryx taeniolatus ) are found off the coast of south and east Australia. Just like seahorses , the male seadragon is tasked with caring for its eggs. The bright pink eggs are placed by the female on a brood patch on the underside of the male where they are incubated and then hatch after about six weeks. “The male weedy seadragon is entrusted with the pink, fertilized...Read more

This rare staurozoan , or stalked jellyfish ( Haliclystus californiensis ) is about 2 centimeters in length and was collected off the coast of California. Unlike the traditional bell-shaped floating jellyfish, staurozoans live attached to rocks or other hard surfaces and mostly live in cold water. They tend to blend in with their surroundings, so often go unnoticed except to those who seek them...Read more

This well-preserved fossil is the only intact partial skull ever found of a white shark that lived about 6.5 million years ago called Carcharodon hubbelli . The fossil jaw contains 222 teeth, some in rows up to six teeth deep, and may provide evidence that modern day great white sharks evolved from the ancestors of mako sharks, not the megalodon.Read more

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 with humans. In addition to gaping, sharks have six highly refined senses for both hunting and communication: smell, hearing, touch, taste, sight, and electromagnetism. These finely honed senses coupled...Read more

This foraminifera was collected as it floated about 3 meters below the surface off the coast of Puerto Rico. The central dark area is the shell surrounded by spines. The tiny yellow dots are symbiotic algae, which live in the protoplasm of the host organism. When the foraminifer dies, the spines fall off and only the shell is preserved in the fossil record. Shell building animals like forams will...Read more

The larger fish in this picture are called sweetlips ( Plectorhinchus ) because of their big, fleshy lips. There are over thirty species of sweetlips, which tend to live on coral reefs in small groups. “On an afternoon dive, I spotted a small group of sweetlips in the current among a shoal of juvenile convict blennies. It took me some time to get close to the fish without spooking them. I took...Read more
