Fishing: the rarest in the world in Mexico, at the site of the tsunami

Southeast Mexico was hit by a earthquake which resulted in two casualties. Fortunately, the earthquake did not cause a tsunami, at least not in Mexico. In the Death Valley, 1500 km away, the earthquake triggered a so-called “desert tsunami” in a small underground pool. In addition, it has disrupted the lives of about 200 small fish of the species Cyprinodon diabolis.

This is the rarer fish in the world the small pool is called the “devil’s hole”. A warm water pool of 22 meters long and 3.5 meters wide. The pool is the entrance to a series of 100 meter deep, unexplored underground caves. The latter is inhabited by the cyprinodon, a small blue fish 3 cm long if it is a male, while it is yellow if it is a female. Its habitat is limited to the small pool, how it got there is unknown. This made it the rarest fish in the world. In the “devil’s den” life is peaceful, but sometimes an earthquake can disrupt the peace.

The earthquake that hit Mexico reached the series of caves, increasing in intensity and triggering a small tsunami. The small swimming pool was also shocked by the earthquake in 2019, when the waves were up to 5 meters high. No casualties among the cyprinodons, but the seismic waves have disrupted the carpet of algae growing on the cave walls. This can lead to a famine of food for the rarest fish in the world.
