Cryptocentroides
Cryptocentroides is a genus of anglerfish in the family Centrophoridae. These fish are known for their distinctive appearance, with a long, slender body and a large, bulbous head. They are found in the deep waters of the Atlantic, Pacific, and Indian Oceans, typically at depths of 1,000 to 3,000 meters.
Common Names
Cryptocentroides are often referred to as "gulper sharks" or "swallowers" due to their ability to engulf prey larger than their heads. They are also known as "deep-sea sharks" or "lantern sharks" because of their bioluminescent lures.
Characteristics
Members of the genus Cryptocentroides are characterized by the following features:
- Slender, elongated body
- Large, bulbous head with a protruding snout
- Small, weak teeth
- Bioluminescent lure located on a long, slender illicium (fishing rod) protruding from the snout
- Two dorsal fins, the first with a spine
- Two pectoral fins
- Two pelvic fins
- One anal fin
- One caudal fin
Environment
Cryptocentroides species inhabit the deep waters of the oceans, typically in the bathypelagic zone (1,000-4,000 meters). These environments are characterized by high pressure, low temperatures, and limited light. Cryptocentroides are adapted to these extreme conditions and are often found in association with seamounts and canyons.
