Is a limpet a snail?
The common limpet is an herbivorous marine snail that lives along the rocky shores of Western Europe. As they live in the intertidal zone (the area along the shore between the high tide and low tide sea levels), these limpets are extremely well adapted to an amphibious life.
How do limpets breathe?
They feed by scraping the radula (“tongue”) across the rock surface. As limpets settle down they rotate the shell and grind it into rock which produces a good fit but also, on death, leaves a scar on the rock surface. To breathe they remove oxygen from the water. This is drawn in to the gills via a hole above the head.

Is limpet teeth stronger than diamond?
“So we were quite happy that the limpet teeth exceeded that. “One of my colleagues on the paper, from Italy, found some exotic spider silk that was about 4.5GPa, and we measured about 5GPa.” This measurement is about the same as the pressure needed to turn carbon into diamond beneath the Earth’s crust.
Which animal has the strongest teeth in the world?
Snails have the most teeth of any animal But that’s not even the most shocking part: The teeth of an aquatic snail called the limpet are the strongest known biological material on Earth, even stronger than titanium!
