List of poisonous 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.

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.

Mammals

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

Birds

Snakes

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

Salamanders

Pacific newts or Western newts^[7]

Fish

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

Cephalopods

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]
