When we think of a species that we consider in danger of extinction or at least consider that it is being eaten, immediately comes to mind “the bass”, “Chad” and other species that we are dealing with and concern us as anglers, however there are other marine species of our environment and close to us who are in danger of extinction and perhaps ignore their existence.
Today we’ll talk about sailing Molly, endemic fish of the Yucatan peninsula which is disappearing from our shores due to the destruction of the swamp which is their natural habitat.
This fish, endemic to the peninsula and discovered in 1936 by the American researcher A.S.Pearse in the swamp of progress is distributed along the coast of the Peninsula, but mainly in the State of Yucatán. He lives in brackish and freshwater springs.
Its head is orange and the body with small greenish-blue spots symmetrically located throughout the body of this.
The colors on the back are more alive than in the womb. The large dorsal fin of the male has black dots with blue Center, and the edge is also black.
These colors may vary according to the place where they have their habitat, since that is a species that also lives in freshwater to slightly brackish.
The female is basically the same pigmentation of the male with the only difference that is slightly paler. The dorsal fin is small in contrast to the male, the same happens with the total size of the fish, the size of the female hardly reaches between 4 and 7 cm long while the male may reach up to 9 centimeters.
It is a viviparous fish, i.e., their young are born alive, with marked sexual differentiation between male and female. Their fertilization is internal, for which the anal fin of the male is modified into an organ that is called gonopodium. It has very small teeth and the ventral fins of the males are larger than the females.
It is naturally in swamps and springs of the coast, but also in the cenotes of the interior of the State which was introduced there to control the larvae of the mosquito that transmits malaria, since among its food are the larvae of the species that transmits the disease, the Anopheles mosquito.
Today, the species is confined just to the West of the swamp’s progress party, since the water flow of the mangroves that form it has affected to such an extent that the species has deteriorated much in your number, this is due to bad planning and construction of roads and public spaces were not present there at the beginning of the last century.
It is therefore very important that we take care of the cleaning of our fishing spot (see this article) and when we go collect all the rubbish we do and leave it in the place intended for this purpose. Many species depend on its existence by what we have done, we do and we do it in the future. Reciprocate by what they have done for us in the past, as their assistance against malaria in the case of this species,… is part of our responsibility as a humanity that we claim to be.
