Signaalejaja

Signaalejaja, also known as the Signal Eel, is a species of eel found in the coastal waters of the eastern Atlantic Ocean, from the Bay of Biscay to the Gulf of Guinea. It is characterized by its distinctive coloration, which includes a series of dark vertical bands on a light background, and a prominent dark spot on its tail fin. The species is known for its ability to produce a strong electric field, which it uses for communication and possibly for detecting prey.

Signaalejaja is a small eel, typically reaching a maximum length of about 30 centimeters. It is a benthic species, living near the seafloor in shallow waters. Its diet consists primarily of small crustaceans and other invertebrates. The eel is oviparous, meaning it lays eggs, which are guarded by the male until they hatch.

The scientific name for the Signal Eel is Nettastoma melanurum. The genus name, Nettastoma, is derived from the Greek words "nettos" meaning "net" and "stoma" meaning "mouth," referring to the eel's feeding method. The specific epithet, melanurum, is derived from the Greek words "melas" meaning "black" and "oura" meaning "tail," referring to the dark spot on the tail fin.

The Signal Eel is of interest to scientists due to its unique electric communication system. However, it is not considered a commercially important species and is not currently threatened with extinction. Its conservation status is listed as Least Concern by the International Union for Conservation of Nature.
