Santa Cruz de Tenerife 14 Feb. (Europa Press) –
The specimen of the deep-sea species known as ‘Black Devil’ is currently awaiting preservation this week at the wet collection facility of the Museum of Natural Sciences (MUNA) in Santa Cruz de Tenerife. It is now stored in a solution of ethyl alcohol to ensure its viability for research purposes, and the possibility of exhibiting it to the public at specific displays is not excluded.
The fish, an adult female that typically resides at abyssal depths, was discovered very near to the surface and approximately two kilometres from the shore, albeit in a severely compromised state of health before succumbing a few hours later.
The condition of the specimen was described as “not very promising,” despite its death occurring shortly after discovery.
It has been stated that, likely, “we may never know” the reasons for this species surfacing from such depths. However, various factors could be considered, such as being swept away by ocean currents, suffering from a disease, or being impacted by some form of deep-sea fishing activity.
Known scientifically as ‘Melanocetus Johnsonii’, this species inhabits depths ranging generally from 200 to 2,000 metres. Its most distinctive feature is the dorsal appendage, which is populated with bioluminescent bacteria that it employs to lure its prey in the pitch-black surroundings of the deep.
Typically, only larvae or specimens in a deteriorated condition have been recorded near the surface, and the females are larger than the males, reaching lengths of up to 18 centimetres.
This discovery could hold significant importance for biogeography, particularly regarding species distribution. It is especially relevant in the realm of genetic analysis that could reveal potential relationships between specimens within the abyssal environment.
“It can assist us in understanding a bit more, depending on genetic affiliations, what occurs in the depths of the ocean,” remarked the museum curator in comments made to Europa Press.
