Gorgasia

Gorgasia is one of the two genera that belong to the subfamily Heterocongrinae. This genus is classified by the behavioral pattern of burrowing 75% of their bodies in the sandy substrate they live in and protruding their upper body into the water current above, giving the appearance that they are planted into the ground. This protruding behavior serves a multipurpose functionality to their survival.

waters on continental shelves, typically near coral reefs. During their life cycle, this genus will spend their larval stages in the epipelagic portion of the ocean until they become juveniles. At this time, they will swim down to the sandy substrate of the benthic zone and burrow themselves. The species belonging to this genus vary in the depths at which they are found on the continental shelf. A majority of the species are found between 10–20 meters with some being found as deep as 220 meters The map to the right shows this genus is widespread across the globe with a high concentration around the Southwestern Pacific Ocean and the Indian Ocean, with other populations found in the Eastern Pacific Ocean around Latin America and the Eastern Atlantic in the Gulf of Guinea. == Reproduction and life span ==
Reproduction and life span
Adults will reproduce sexually with each other. 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. Garden eels are oviparous and practice external fertilization. This means that a female will expel her eggs into the surrounding substrate and they will be fertilized by the male secreting his sperm onto them. 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. 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. At this point they are sexually mature and will begin the cycle over again. Although there is variability between the species of this genus, average longevity of life is estimated at 6 years of age for garden eels with the range spanning from 4 years to 10 years. ==References==
