Is Volcano snail exist?

The scaly-foot snail (Chrysomallon squamiferum) survives in what researchers have called the ‘impossible living conditions’ of underwater volcanic vents. Enduring searing temperatures, high pressure, strong acidity and low oxygen, it is the only living creature known to incorporate iron into its skeleton.

The species has recently been listed as ‘Endangered’ on the IUCN Red List. The foot of the snail is large and covered in hundreds of overlapping hard dermal sclerites which give it its name.

How does a snail’s digestive system work?

Process of digestion in snails The alimentary tract of land snails is remarkably simple, possibly because of terrestrial life styles. The alimentary canal is usually divisible into buccal mass, esophagus, crop, stomach, intestine and rectum along with appendages like salivary and digestive glands (hepatopancreas) [55].
