Taipoxin is a potent myo- and neurotoxin that was isolated from the venom of the coastal taipan Oxyuranus scutellatus or also known as the common taipan. [1] Taipoxin like many other pre-synaptic neurotoxins are phospholipase A 2 (PLA 2) toxins, which inhibit/complete block the release of the motor transmitter acetylcholine and lead to death by paralysis of the respiratory muscles ().

In addition to killing the prey, part of the function of a haemotoxic venom for some animals is to aid digestion. The venom breaks down protein in the region of the bite, making prey easier to digest. The process by which a haemotoxin causes death is much slower than that of a neurotoxin. Snakes which envenomate a prey animal may have to track ...
This neurotoxin was isolated and described in 1975 and named "Mojave toxin". [28] [29] In 1978, an area in southcentral Arizona was identified where the venom of C. scutulatus is significantly less lethal to laboratory mice than venom from the balance of the species' range. The more lethal (and more widely distributed) variant was named "venom ...
The toxin is variously used by animals as a defensive biotoxin to ward off predation, or as both a defensive and predatory venom (e.g., in octopuses, chaetognaths, and ribbon worms).

Older workers deliver less venom when they sting, but middle-aged workers and nest-defenders deliver much higher quantities. [13] Like all fire ant species, venom is secreted by the venom gland and is stored in the poison sac. [14]
