Prehistoric Frilled Shark
Flaring the gills that give the species its name, a frilled shark swims at Japan's Awashima Marine Park on Sunday, January 21, 2007. Sightings of living frilled sharks are rare, because the fish generally remain thousands of feet beneath the water's surface. Spotted by a fisher on January 21, this 5.3-foot (160-centimeter) shark was transferred to the marine park, where it was placed in a seawater pool. "We think it may have come to the surface because it was sick, or else it was weakened because it was in shallow waters," a park official told the Reuters news service. But the truth may never be known, since the "living fossil" died hours after it was caught.
Giant Hatchetfish
The giant hatchetfish is found in deep tropical and subtropical waters of all oceans, except the north Pacific. Its length is between 8 and 12 cm. The giant hatchetfish is a deep-bodied species with large eyes that are directed upwards, enabling prey to be silhouetted against the faint light coming from the surface, and a large mouth also directed upwards
Deep-sea stargazer
Stargazers are a family of muscular bulldog-like fishes that typically bury in the seafloor and ambush passing prey. Stargazers are the ultimate ambush predator, with the eye sets on top of the head allowing it to be almost completely hidden. This is combined with an electrical capability which can be used to stun its prey.
Clown Triggerfish
The Clown Triggerfish or Big-spotted Triggerfish is one of the most spectacular looking marine species. This species grows to 50 cm in length and is usually found in the warm parts of the Pacific Ocean, Indian Ocean and the Red Sea. Even though its appearance is quite innocent; this fish is an aggressive carnivore that primarily preys on shelled invertebrates.
Black Swallower
The black swallower (Chiasmodon niger) is a deep sea fish that has the ability to extend its stomach 3 times its size so that it can swallow fish that are bigger than itself. It can be found in deep seas up to 1,500 meters or in hot tropical waters. It creates its own light because of the darkness found in some parts of the Pelagic zone. The black swallower can grow up to 25 centimeters.
Black Chimaera
Chimaeras are related to both sharks and rays. They are jawed fish with paired fins, paired nostrils, scales, two-chambered hearts, and skeletons made of cartilage rather than bone. Chimaeras grow up to two meters long, are found in the ocean floors and have a venomous spine which they use for defense purposes.
