Dominick Legotte Marine Cone Snails

Cell SignalingUsually, any cell communication process has one or two ligands, or signals. Marine cone snails produce over 100,000 different types of ligands that makes their venom so diverse. These toxins are held in wells dorsal to the snails' teeth. As their teeth are shot into their prey, the other organism has a slim chance of escaping all of the different toxins used by the snail. The receptors for the snails are nicotinic acetylcholine receptors. Just like most venoms, once it enters the organism, it attacks the immune system slowly but deadly, ruining everything in the body. The prey, once bitten, quickly stiffens up and becomes immobilized. The cells in the prey quickly stop working.

1) Marine cone snails are predators that use venom against their prey.2) Marine cone snails use their very sharp teeth to secrete their deadly venom into their prey. These snails are famous for their fascinating outer shells, but not many people realize how dangerous and predatory they actually are.3) The toxins found in their poison are being researched and tested to use in the medical field.

Just like any organism, without the toxin in the body, the organism functions normally with no cellular or immune issues.

When the snails' toxins enter it's prey, the cells and the body's systems quickly freeze up and stop what they're doing. The toxin kills off the cells and deteriorates their functions.
