Acromegalomma
Acromegalomma is a genus of deep-sea anglerfish in the family Melanocetidae. These fish are characterized by their distinctive appearance, featuring a large, fleshy lure known as an esca that extends from their heads. Acromegalomma species are found in the deep ocean, typically at depths of 1,000 to 3,000 meters. They are known for their bioluminescent lures, which emit a faint glow to attract prey in the darkness. The genus currently comprises three species: Acromegalomma munidae, Acromegalomma antarctica, and Acromegalomma owstoni.
Common Names

Characteristics
Acromegalomma fish share several key characteristics, including:
- Large, fleshy esca: This lure is located on the top of the head and is used to attract prey. The esca is often bioluminescent and can be highly elaborate in some species.
- Small, compressed body: These fish are typically small, with a compressed body shape. Their bodies are often dark in color, helping them blend into the deep-sea environment.
- Barbels: They have a number of barbels or filaments around their mouths, which are sensory organs that help them detect prey in the dark.
- Bioluminescence: They are known for their ability to produce light, which is primarily used to lure prey. The light is generated by symbiotic bacteria living within the esca.
Environment
Acromegalomma species inhabit the deep ocean, typically at depths of 1,000 to 3,000 meters. They are found in various regions of the world, including the Atlantic, Pacific, and Indian Oceans. These fish live in an environment with low light levels and high pressure.
