How snails breathe

People might sometimes wander how snails breathe because it seems that snails do not have noses or something to breathe with. However, a website about land snails tells this. "Snails breathe by taking air into a visceral cavity that is richly supplied with blood vesselsthe snails version of a lung. When the snail extends from the shell, the access pore can be seen opening and closing just below the margin of the shell on one side. Also, the snails heart can be seen pumping blood by placing a snail on the lens of a flashlight and carefully looking through the translucent shell." This tells that snails have a way to breathe and a tool to breathe with but what is funny about snails breathing is that some of the people say that snails breathe through their feet. But actually that’s a mistake because snails do not breathe through their skin. They breathe with skins though. I found appropriate information for that statement and here it goes. “Snails "breathe" through their skin and through an opening called the pneumostome visible on the right side of their bodies.” So this proves that snails do not breathe through their feet but skin. They have their own tool for breathing. Sorry for making you guys feel stupid but it’s true. But if you are still interested in the way of animals breathing try to find about turtles and dragonflies. They some funny ways to breathe.
