Venomous mammals are synapsids of the class Mammalia that produce venom, which they use to kill or disable prey, to defend themselves from predators or conspecifics or in agonistic encounters. Mammalian venoms form a heterogeneous group with different compositions and modes of action, from four orders of mammals: Eulipotyphla , Monotremata ...
Many species of octopus, squid, and cuttlefish make use of venom when hunting their prey. The blue-ringed octopodes ( Hapalochlaena spp.) produce tetrodotoxin , which is extremely toxic to even the healthiest adult humans, though the number of actual fatalities they have caused is far lower than the number caused by spiders and snakes, with ...
[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.
Venom has evolved many times in multiple phyla, each having developed their own unique types of venom and methods of delivery independently. [2] However, due to the excessive amounts of venomous animals in the world, they are the major cause of animal-related deaths (~ 57,000 in 2013) than non-venomous animals (~22,000). [ 3 ]

A unique feature of the venom is the presence of a D-amino acid. This is the only known such example in mammalian systems. [8] This venom appears to be related to that of several species that are not part of the platypus's evolutionary lineage, such as certain fish, reptiles, insectivores, and spiders, sea anemones, and starfish.
