Scary Fish

I have a unhealthy obsession with all things creepy. Horror movies, aliens, paranormal activities, strange desolate places, and scary animals! But I never have the guts to do these stuff alone cause I'm too chicken for it, which means my friends/family have to sadly sacrifice their well-being each time my obsession kicks in!

I was browsing through some creepy fish online and look what I found!


Why would that guy even touch it!! It looks human! It even looks like it has 'blinkable' eyes!

And look at this!

The Snaggletooth fish that resides in Australian waters! Gulp.

But what strikes my fancy most is the Blind Cave Fish, which I have seen in a trip to China in the past. This creepy fish is devoid of eyes after centuries of evolution!

Check this story out!

Rediscovered Blind Fish May Be Last of Its Kind

In 1962 a strange blind fish was captured in a communal water well in Minas Gerais, Brazil. Ichthyologists identified it as a new species of Characiformes, an order that includes tetras and piranhas, but outside that one lonely specimen, the fish was never seen again.

Now, a team of researchers from the Federal University of Sao Paulo have rediscovered the fish—though the small population may already be doomed to extinction.

The team, led by Dr. Cristiano Moreira, began by interviewing locals living around the area of the first discovery. From these interviews, they collected several reports that the fish had been seen swimming in communal wells.

However, because the region is so dry, people rely on underground wells—and even these often end up being free of standing water. Moreira explained:

This was one of the problems we encountered to find this fish, since most of the open wells we could access to collect or put traps were dry.

Eventually, the team found two pools with enough water that they could place traps and collect fish.

And collect they did. The team ended up capturing 34 individuals that proved to be the elusive Stygichthys typhlops.

The rediscovery has allowed researchers to gain a better understanding of the fish, but much remains unknown.

Moreira commented that:

Morphologically, Stygichthys is very different from any species in the group, so much so that we are still not able to say to which species it is more related.

One thing is certain: The species is highly threatened.

Moreira explained that it is likely the species is mostly extinct, with only this one group surviving by virtue of it's until-now inaccessible habitat—what conservationists call a "relic species."

This protection, however, is vanishing rapidly. As surface wells become increasingly rare, people are pushed farther underground in search of water—and these deep pools, and the rare fish that call them home, face a dry future because of it.

Moreira explained that "this species seems to be the most threatened underground fish species in Brazil," likely relegated to a habitat only 25 kilometers long. And, he added, the withdrawal of water from this tiny aquifer will mean certain extinction for the species.

I just love amazing stories like this!
