Indian cobra venom contains primarily post-synaptic neurotoxin and cardiotoxin strong. Toxins acting on neuronal synaptic cleft, thereby paralyzing muscles, and in the harsh bite cause respiratory failure or heart failure. Venom components include enzymes such as hyaluronidase that cause lysis and increase the spread of venom. Symptoms of envenomation can manifest between 15 minutes to 2 hours after the bite and can be fatal in one hour in the case of severe envenomation.
3. Box Jellyfish

The box jellyfish is the transparent light blue, bell or cube with 4 sides. Its speed to 4 knots. Jellyfish have sting cells (cnidocyte) containing a nematocyst in the tentacles. A capsule (nematocyst) the tool can (cnidoblast) consists of a trigger and stinging structure. When the victim's contact with the tentacle, hundreds of thousands of nematocyst issued. Nematocyst discharge pressure forcing rapid spread, paralyzing toxin.
There was no chance of surviving unless treated quickly can sting. Taste is very ill to anaphylactic shock and drown before reaching the beaches though not all work.People who are stung should be treated as victims of snake bite and was immediately taken to the hospital after first aid. Highly toxic sting can cause death.Predator is very toxic.
