List of venomous animals

Venomous animals include:

Many venomous animals, such as this blue ringed octopus (genus Hapalochlaena), are brightly colored or can display bright colors to warn potential predators.

Arachnids

• Strictly speaking, all spiders and scorpions possess venom, though only a handful are medically significant.
• Australian funnel-web spider^[1]
• Black widow spider
• Brazilian wandering spider
• Brown recluse spider^[2]
• Katipo
• Redback spider
• Tarantulas
• Scorpions: Of more than a thousand known species of scorpion, only a few have venom that is dangerous to humans.^[3]
• Paralysis tick

Cephalopods

• Blue-ringed octopus^[4]

Cnidaria

• Jellyfish sting using microscopic cells called nematocysts, which are capsules full of venom expelled through a microscopic lance. Contact with a jellyfish tentacle can trigger millions of nematocysts to pierce the skin and inject venom.^[5]
• Portuguese Man o' War
• Sea Anemones
• Some Corals

Crustacean

• The remipede Xibalbanus tulumensis looks like a white centipede with a long segmented body and scores of legs which display a swimming motion. They live in underground caves of Mexico and Central America. Although blind, they are formidable predators, and feed on the shrimp that share their underground pools.

Dinosaurs

• Some scientists have proposed that Sinornithosaurus had a venomous bite, but recent evidence suggests otherwise.^[7]

Fish

There are at least 1,200 species of venomous fish, and they include

• The Stonefish, Lionfish, Scorpion Fish, Stargazer, and Toadfish (Daector and Thalassophryne).^[8]

• Chimaeras

Insects
