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.
- 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
 - 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
- 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
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]
