List of poisonous animals

This article is about animals poisonous on contact or when ingested. For animals that inject venom, see list of venomous animals.

The following is a list of poisonous animals, which are animals that passively deliver toxins (called poison) to their victims upon contact such as through inhalation, absorption through the skin, or after being ingested.^[1][2] They are often distinguished from venomous animals, which actively inject their toxins (called venom) into their victims through a venom apparatus such as fangs or a stinger.^[1][2] The only difference between poisonous animals and venomous animals is how they deliver the toxins.^[3][2] This list deals exclusively with poisonous animals.

The hooded pitohui. The neurotoxin homobatrachotoxin on the birds' skin and feathers causes numbness and tingling on contact.

Poisonous animals

This list is a partial list of animals that are poisonous to humans and other animals in that their flesh is toxic if consumed, or in some cases if they are touched:

Frogs and toads

Frogs

• Corroboree frog
• Mantella
• Poison dart frog

  

  The bright colors of poison dart frogs warn predators of their toxicity.

Toads

Some of these toads are "milked" for their bufotoxins.

• American toad
• Asiatic toad
• Cane toad
• Colorado River toad
• Common toad
• European green toad
• Fowler's toad

Mammals

• Slow loris (usually thought of as venomous, but they also lick their fur, making it toxic)^[4]

Birds

• Pitohui
• Blue-capped ifrit
• Shrikethrushes^{[citation needed]}
• Spur-winged goose (diet-dependent)^[5]
• Common quail (diet-dependent)
• Carolina parakeet

Snakes

• Rhabdophis keelback snakes
• Garter snake (diet-dependent, when feeding on Pacific newts)^[6]

Salamanders

Most birds dislike the taste of monarch butterflies; they contain toxins from poisonous milkweed, ingested as caterpillars.

• Pacific newts or Western newts^[7]

Fish

• Tetraodontidae (Blowfish, Pufferfish)
• Greenland shark
• Barracuda (age and diet dependent)

Cephalopods

• Blue-ringed octopus
• Pfeffer's flamboyant cuttlefish^[8]

Insects

• Blister beetle
• Diamphidia
• Cinnabar moth
• Certain tiger moths (Erebidae)
• Birdwings
• Milkweed butterflies (include Monarch butterfly)
• Battus (butterfly)

Crustaceans

• Gorilla crabs (Xanthidae)

Cnidarians

• Some members of the genus Palythoa produce the highly toxic palytoxin
• Rhodactis species^[9]

Echinoderms

• It is common for sea cucumbers like Pearsonothuria graeffei to protect itself with toxins^[10]
• Actinopyga agassizii a toxic sea cucumber
• Some starfish, like Plectaster decanus, are poisonous

Annelids

• The polychaete worm Hediste diversicolor^[11]
• Halla parthenopeia^[12]

Nemerteans

• Antarctonemertes valida is one of several nemerteans which make use of defensive toxic secretions^[13]

Flatworms

• Bipalium kewense, the hammerhead flatworm, is coated in toxic mucus^[14]

Sponges

• Negombata magnifica, the toxic finger-sponge, is one of many toxic species of sponges

Placozoans

• Trichoplax use large specialized cells to release antipredatory toxins^[15]
