A fish is any member of a set of organisms that contain all gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, collectively forming the olfactores. Included within this definition are the dwelling hagfish, lampreys, and cartilaginous and bony fish, as well as various extinct related classes. Have a look at some venomous fishes beneath:

1. Stonefish
The stonefishes are poisonous, dangerous and even fatal to humans. It's one of the most venomous fish presently known on the planet. They are located in the coastal areas of this Indo-Pacific. Stonefishes are primarily marine, although some species are known to dwell in rivers. The stonefish, derives from the stonefish's ability to camouflage itself using a gray and mottled color similar to the color of a stone.

Swimmers may not detect them and may inadvertently step on themtriggering a sting. After the stonefish is disturbed, it may inject an amount of venom proportional to the amount of pressure applied to it. Stonefish bites are equally potentially lethal and incredibly painful. Stonefish being able to stay out of this water for up to 24 hours. They frequently cannot be easily viewed as they seem similar to rocks or coral.

Lionfish
Pterois is a genus of venomous marine fish, also popularly referred to as lionfish and it's native to the Indo-Pacific. It's characterized by conspicuous warning coloration using white, red, creamy or black bands, showy pectoral fins and poisonous spiky fin rays. They are well-known for their ornate beauty, venomous spines and special tentacles. Lionfishes can live out of five to 15 years.

Moray eels, bluespotted cornetfish and large groupers, such as the tiger grouper and Nassau grouper are predators of lionfish. Sharks are also thought to be capable of preying on lionfish without any ill effects in their spines. Pterois venom can cause systemic effects such as extreme pain, nausea, vomiting, fever, breathing problems, convulsions, nausea, redness in the affected area, headache, tingling, paresthesia, heartburn, diarrhea and sweating.

Scorpionfish

They are widespread in tropical and temperate seas, but largely found at the Indo-Pacific. Many inhabit shallow waters, but a few live as heavy as 2,200 m. Many scorpionfish, such as the stonefish, wait disguise for prey to pass them before swallowing.

Stargazer Fish
The stargazers are a family, Uranoscopidae, of perciform fish that have eyes on top of their heads, thus the name of this fish. The family comprises about 51 species (one extinct) in eight genera. All Species are marine and discovered globally in shallow and deep saltwaters. In addition to this top-mounted eyes, a stargazer also has a large, upward-facing mouth at a large head.

Stargazers are poisonous. They have two large venomous spines situated supporting their opercles and above their pectoral fins.

Toadfish

Toadfishes are observed globally. Many toadfish are marine, although a few are found in brackish water. Toadfish are benthic ambush predators that favor sandy or muddy substrates in which their cryptic coloration helps them avoid detection by their own prey. Toadfish are well-known for their ability to"sing", males in particular with the swim bladder as a sound-production device used to attract mates.
