Not all fish are edible. There are fishes that are not suitable for human consumption. There are more venomous fish than venomous snakes. There are at least 1,200 species of venomous fish in the world but some venomous fish are also edible.
1. Antennata Lionfish (Pterois antennata)

The Antennata Lionfish is the first in our list. Look at her; she's really such a beauty to admire. This species of beautiful but venomous fish also known as the Ragged-finned Firefish or Spotfin Lionfish, has red, white, and black vertical stripes along the body; large, fan-like pectoral fins; and tall, quill-like dorsal fins. Lionfish in general are notable for their extremely long and separated spines, and have a generally striped appearance, red, brown, orange, yellow, black, maroon, or white. Lionfish have venomous spines that are deadly to their prey, but usually not to humans (though the venom is used purely for defense, not attack). If a human is envenomated, that person will experience severe pain and possible headaches and vomiting. A common treatment is soaking the afflicted area in hot water, as very few hospitals carry specific treat-ments. However, immediate emergency medical treatment is still advised, as some people may be more susceptible to the venom than others.
