modified first vertebrae that makes a wing-like shape just above the swim bladder. However, in males there is a free floating bone that curves along a modification of the third through sixth vertebrae and attaches to the swim bladder. This is called a rocker but has not been seen in action so the function is unknown. In females this area is not modified and has two hollow protuberances coming directly off of the vertebrae.

burrowing has been caught on video in multiple species and occurs tail first, the fish backing up and down into soft sand or mud until covered. In soniferous species, a loud jackhammer-like sound is emitted by males for the attraction of a mate. They are thought to feed on small invertebrates such as shrimp or worms.

Though fairly small, the band cusk-eel has a complicated skeletal system. There are 20 ribs to allow for flexibility and 66-69 vertebrae along the spinal cord. This specific variation is a dull tan and lacks scales on the top of the head. The dorsal and anal fins are continuous with the caudal and

Little is known about the behavior of cusk eels in general and what is known is not often specific to species. Many cusk eels are known to cohabitate alongside or within the bodies of invertebrates. Most are known to burrow during the day, possibly to conserve energy and/or avoid predators. This

Male band cusk eels lack copulatory organs. As a result, eggs are externally fertilized and kept together in gel-like clumps, which float near the surface. The juveniles are rarely seen except in two studies of multiple dusk-eel variations. One study found larvae near the surface and traveling

Though the color of each sex varies little, in the development of anatomy in band cusk eels there is a noticeable difference. Both have a hardened swim bladder (suggesting that perhaps females use it for sound too) but males alone have a structure called a 'rocker'. All individuals possess a

Cask eels tend to live in the bottom of shallow areas of water and take shelter in anything from caves to other invertebrates. Crevices and mud or sand burrows can be home to solitary fish or groups. A full distribution map of this species has not been made.

Its range under water can be between 0.5–7 m (1.6–23.0 ft), but usually it is found deeper than 18 m (59 ft) below the surface. This species was first seen in the Key West area near
Florida, USA in 1874 and
