Each species is diverse in morphological patterning, hosting flat, spotted, freckled, and banded colorations, while still hosting some key defining morphology such as a short snout, large lips, large eyes, dagger shaped teeth, and a single fused anal, dorsal, and caudal ray fin.

When time for breeding, adults in genus Gorgasia will increase the density of their colonial living until their burrows begin to overlap one another.

Males will compete for proximity to a female's burrow, often biting at each other's body and face and in rare instances mortally wounding one another.

Then, when fertilized, eggs will float to the epipelagic zone of the continental shelf where they will mature and hatch into the larval stage of development called leptocephalus.

These larvae will be translucent, a camouflaging technique for the open ocean in order to avoid predation until they are able to mature more.

[4] When almost one year of age, the juveniles will begin to form their morphological colorings and will swim to the benthic zone and build their burrows.
