It has been argued that only primates and humans can feel "emotional pain", because they are the only animals that have a neocortex – a part of the brain's cortex ...
The most common jellyfish involved is the Carukia barnesi, a species of Irukandji jellyfish. [4] Those stung may experience severe or even excruciating pain. The syndrome was given its name in 1952 by Hugo Flecker, after the Aboriginal Irukandji people who live in Palm Cove, north of Cairns, Queensland, Australia, where stings are common. [6]

She warned against picking up jellyfish, as stinging species like Portuguese man o’ war and lion’s mane can still hurt humans even when the jellyfish is dead.
The effects of stings range from mild discomfort to extreme pain and death. [145] [146] Most jellyfish stings are not deadly, but stings of some box jellyfish (Irukandji jellyfish), such as the sea wasp, can be deadly. Stings may cause anaphylaxis (a form of shock), which can be fatal. Jellyfish kill 20 to 40 people a year in the Philippines alone.
A typical human cutaneous nerve contains 83% C type trauma receptors (the type responsible for transmitting signals described by humans as excruciating pain); the same nerves in humans with congenital insensitivity to pain have only 24-28% C type receptors. [23] The rainbow trout has about 5% C type fibres, while sharks and rays have 0%. [24]
