Description

The spotted garden eel is a small fish that can reach a maximum length of 40 centimetres (16 in; 1.3 ft). Its body is anguiform (eel-like): long, thin, with a circular cross-section (14 millimetres (0.55 in) in average diameter) and a head of the same diameter as the body. The head appears shortened because the large mouth is close to the also large eyes. Nostrils are small and positioned in the center of the upper lip.

The body is white and covered with many small black spots. The spotted garden eel has three larger distinctive black spots; the first identifies the gills opening and the position of the tiny pectoral fins, the second is located in the central part of the body and the third one surrounds the anus. Juveniles have a very thin black body. [3]

Distribution and habitat

Colony of spotted garden eels at the Monterey Bay Aquarium.

The spotted garden eel is widespread throughout the tropical and subtropical waters of the Indo-Pacific from the eastern coasts of Africa including the Red Sea to Polynesia, and south from Japan to New Caledonia. [4]

It lives exclusively in variously sized colonies on sandy bottoms that are exposed to currents, at depths from 15 to 45 meters. [5] It digs a burrow from which emerges about a third of its body pointing their mouths towards the underwater current to catch drifting food. [6]

Biology

As in other heteroconger species, individuals rarely leave their burrow once it is finished, but will move burrows closer together during breeding season until contact between partners is possible. Fertilized eggs and juveniles have a planktonic period before reaching sufficient size to start living in the substrate. [3]

<i>Heteroconger</i> Genus of fishes

Heteroconger is a genus of marine congrid eels. These small, slender garden eels live in groups where each individual has its own burrow. Usually, only the head and front half of the body is visible. The greatest species richness is in the Indo-Pacific, but species are also found in the warmer parts of the Atlantic and the eastern Pacific. Its name relates to how a huge colony of the eels looks swaying in the current.

Novaculichthys taeniourus, also known as the rockmover wrasse, carpet wrasse, dragon wrasse, bar-cheeked wrasse, olive-scribbled wrasse or reindeer wrasse, is a species of wrasse mainly found in coral reefs and lagoons in the Indo-Pacific region. These include habitats in the Gulf of California to Panama; tropical Pacific Ocean islands including Hawaii; the Philippines, Indonesia and Australia; and the Indian Ocean to the east coast of Africa.

<i>Gorgasia</i> Genus of fishes

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.

<span class="mw-page-title-main">Heterocongrinae</span> Subfamily of Congridae

The garden eels are the subfamily Heterocongrinae in the conger eel family Congridae. The majority of the 36 known species of garden eels live in the Indo-Pacific, but can be found in warm ocean water worldwide. These small eels live in burrows on the sea floor and get their name from the behavior of poking their heads from their burrows while most of their bodies remain hidden. Since they tend to live in groups, the many eel heads "growing" from the sea floor resemble the plants in a garden. They vary in color and size depending on the species. The largest species reaches about 120 cm (47 in) in length, but most species do not surpass 60 cm (24 in). Garden eel colonies can grow as large as one acre in surface area and number up to several thousand individuals.
