What does a radula look like?

As for the radula itself. it is a ribbon-like structure covered with many denticles (tiny teeth). It is movable over the odontophore and is also controlled by muscles. The feeding behavior of marine snails include some that are herbivores, detritus (debris) feeders, scavengers and predatory carnivores.

How does a snail radula work?

Snails and slugs eat with a jaw and a flexible band of thousands of microscopic teeth, called a radula. The radula scrapes up, or rasps, food particles and the jaw cuts off larger pieces of food, like a leaf, to be rasped by the radula.

Why are snails poisonous?

Freshwater snails carry a parasitic disease called schistosomiasis, which infects nearly 250 million people, mostly in Asia, Africa and South America. “It’s one of the world’s most deadly parasites,” says Susanne Sokolow, a disease ecologist at Stanford University’s Hopkins Marine Station.
