Many of the beautiful and colorful fish in the sea are food for larger fish and for humans.
But nature has endowed many of them with powerful forms of defense so that they are not that
easy a prey to their predators.
Up next, we will see: "the most poisonous fish in the world".
Horned Cuckoo-fish Its way of defending itself is very particular,
expelling a very harmful substance when it feels danger.
But such a poison can kill even itself and all the fish nearby.
It measures 15 centimeters or 6 inches, and inhabits coral reefs in the Indian, Pacific
and Atlantic oceans.
It feeds mainly of crustaceans and algae.
Stinging catfish It is native to India and Thailand, in rivers
or lakes with slow currents.
It measures approximately 30 centimeters, or 12 inches, in length.
It is one of the "most lethal fish in the world", because it has relentless stingers,
located in the lateral fins.
Attacked humans have described great pain when they are stung and, to make matters worse,
the poison injected has killed many people, and those who have survived describe serious
lung conditions and serious muscle spasms.
Comb-tooth blenny
It has powerful fangs, with which it attacks the divers or predators, injecting them with
a powerful poison, with effects similar to the heroine, which inhibits the pain during
the bite, but affects in a remarkable way the blood pressure of its victims, giving
it adequate time and conditions to escape from there.
It measures about 15 centimeters, or 6 inches, and inhabits the coral reefs of the Indian
and Pacific oceans.
River skate, or ray This fish has a pointed tail that contains
a sting, which it nails into its chaser, releasing a poison that attacks directly the central
nervous system.
It measures approximately 50 centimeters and its single bite causes a very painful, and
above all serious, injury in humans.
It is found more in areas near the Amazon.
Chimera fish In one of its fins, it hides a deadly stinger,
to attack its possible predators.
If stinging a human being, it could be deadly, but no cases have been recorded, because it
inhabits 550 meters deep in the Pacific Ocean, in the Alaska region.
Spider fish Its habitat in is sandy bottoms of the Atlantic
Ocean.
There, he hides waiting for a delicious prey to pass nearby.
Near the head he has thorns with which it injects a poison that causes strong dizziness
and cramps that could kill a person.
There have been cases of tourists who have accidentally stepped on it, as it often swims
close to the ground.
Also, some fishermen have accidentally suffered from their bites, when unhooking the fish
after catching it.
It has also been seen in Mediterranean waters.
Stonefish It can be camouflaged very easily, thanks
to its physical characteristics, because coral residues adhere to its body.
It likes to hide inside the seabed and among rocks.
For its defense, it has 13 sharp thorns, with a poison that can kill any person.
It inhabits the waters of the Indo-Pacific, as well as those of the Red Sea.
