The cone snail is a slow-moving marine animal that is known for its highly venomous nature. Cone snails are part of a group of around 1,000 species of predatory snails that live in tropical waters all around the world. Despite being slow and not very aggressive, their venom is fascinating to biomedi

Methods of Killing

Although cone snails do not have fangs, they have a harpoon covered in venom that they use to immobilize their prey. The harpoon has a tube-like structure at the end of a venom bulb, and a modified tooth that can shoot out of the tube at 400 miles per hour (644 kilometers per hour). This instantly paralyzes any prey that passes by. The cone snail then uses its large, parachute-like mouth to swallow and eventually spit out the bones a few hours later.

Some cone snails, like the geographer cone, sneak up on sleeping fish and release a cloud of chemicals, including insulin, which numbs and puts their prey into a hypoglycemic coma before consuming them whole.

Other cone snails will strike a fish but not tether it with their harpoon. Although the fish can swim away, it quickly falls under the influence of the snail’s venom. The snail follows its prey and eventually gobbles it up.

These are only a few tactics that cone snails use. According to Safavi, there is much to learn about the various ways that cone snails use their venom in the wild:

“We have limited knowledge of how cone snails use their venom in their natural habitat,” she explains. “My colleague recently discovered that some cone snails use toxins that mimic mating pheromones to attract worms out of their burrows. It’s amazing what these creatures can do.”

Safavi states that cone snail venom has been used in the development of therapies and drugs to treat diabetes and severe pain.
