Stone fish
When viewed from the looks, steemit friends will surely think that this fish is a tame fish who like to move slowly and will not be able to take our lives. However, this fish turned out to be one of the "members" of the world's deadliest marine animal group. The name of the stone fish itself is derived from its ability to change its body color like a chameleon. But this fish is more hiding and waiting for its prey near rocks and sand, so he more often change the color of his body to be like the color of stone and coral. The lethal point of this fish lies in its sharp fin, where the fish's fin is toxic and if exposed to humans will cause tremendous pain for several hours and progressively worsen, resulting in prolonged shock, hypertension, paralysis, and eventually passing away.
