Do cone snails have eyes?

Snails are strange-looking creatures with shells and large stalks sticking out of the tops of their heads. However, snails do have eyes and vision, though the exact location of the eyes and their use depends on the specific type of snail. Snails don’t rely on sight as much as humans, but it’s still one of their senses.

What is cone snail venom made of?

The venom contains about 100 different peptides (short proteins) that act as neurotoxins. Each of the 600 or so species of cone snail has its own unique cocktail of peptides, with very little overlap of peptides among species, yielding >50,000 peptides among the cone snails of the world.

How does the cone snail reproduce?

Reproduction in cone snails has not been widely studied, but it appears that most have separate sexes and are fertilized internally (Rockel et al. 1995). Eggs are laid once a year and attached to substrate in capsules, with each capsule containing a varying number of eggs.

Cone snails are carnivorous, and predatory. They hunt and eat prey such as marine worms, small fish, molluscs, and even other cone snails. Because cone snails are slow-moving, they use a venomous harpoon (called a toxoglossan radula) to capture faster-moving prey, such as fish.

Where are cone snails located?

A cone snail has a cone-shaped shell, a fleshy foot, a head, and tentacles. Cone snails live in the Indian and Pacific Oceans, the Caribbean and Red Seas, and along the coast of Florida. They are not aggressive. The sting usually occurs when divers in deep reef waters handle the snails.
