Palatogobius incendius was discovered by the Curasub deep-sea submarine when initially an invasive lionfish (Pterois volitans) floated into the camera's field of view and oriented itself to barely perceptible fish, capturing them, one by one.
Using a chemical anesthetic, some of these small fish were anesthetized and brought into the submarine with a suction hose.
The animals were scientifically examined, compared with the previously known species Palatogobius paradoxus and Palatogobius grandoculus and described as a new species for the first time.
The publication of this now third species of the genus Palatogobius took place on May 25, 2017.
The very severe decimation of smaller fish species in the Caribbean by invasive lionfish has been reported frequently, but the fact that this campaign of destruction is now moving into much deeper waters can be documented as a further drama.
If no targeted eradication of the invasive and toxic lionfish in the Caribbean takes place, then there is a risk that these greedy permanent predators will permanently damage the populations of native Caribbean fish species.
In its natural habitat, Pterois volitans pushes to maximum depths of up to 55 meters; that these predators push to much greater depths in the Caribbean may already be the result of extreme feeding at more moderate depths.
The lionfish can release 2 million eggs per female, and since there are no natural enemies of the lionfish in the Caribbean, it is expected that these predators will also expand their habitat towards South America.
Since native fish have not "met" the predatory lionfish, they have not been able to adapt to these predators, which devour anything that fits in its mouth.
"Lionfish will eat anything that fits in their gullet - and lots of it. DNA analysis of the stomach contents of 157 of these fish from the Mexican Caribbean revealed 43 different crustacean species and 34 fish species, including parrotfish, French grunt and Caribbean grouper - all important to the diet of the resident population. Without natural enemies, a lionfish eats up to 79 percent of a reef's juvenile fish in less than five weeks." (Source: Spektum.de).
How long the just freshly discovered gobies will still exist in the Caribbean is more than questionable!
First measures were already initiated, the lionfish land as tasty main courses on the plates in different fish restaurants.

Jumping guard
A jumping guard prevents (nocturnal) fish from jumping out.
Wrasses, blennies, hawkfishs and gobies jump out of an unprotected tank in fright if their night rest is disturbed, unfortunately these jumpers are found dried up in the morning on carpets, glass edges or later behind the tank.

A small night light also helps, as it provides the fish with a means of orientation in the dark!
