Otala lactea, known as the milk snail or Spanish snail, is a large, edible [3] species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk, in the family Helicidae, the typical snails. [4] Archaeological recovery at the Ancient Roman site of Volubilis, in Morocco, illustrates prehistoric exploitation of O. lactea by humans. [5]
Once in the tank, it becomes a non-harmful pest. Although Physella acuta can be annoying and reproduce quickly compared to other snails, they can actually be beneficial for your aquarium. They clean algae efficiently due to their speed and reproductive rate, and they help break down old food and feces, ensuring a healthier tank environment.
They use this siphon in order to breathe air while they are submerged in water which has a low oxygen content so they cannot effectively use their gill. [ 6 ] Apple snails use the siphon in a way that is reminiscent of a human swimmer using a snorkel , except that the apple snail's siphon can be retracted completely, or extended to various ...
Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. Ampullariidae). Most feed on algae, but many are detritivores and some are filter feeders.
Biomphalaria glabrata is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.. Biomphalaria glabrata is an intermediate snail host for the trematode Schistosoma mansoni, which is one of the main schistosomes that infect humans. [2]
The anatomy of a common air-breathing land snail: much of this anatomy does not apply to gastropods in other clades or groups. Snails are distinguished by an anatomical process known as torsion, where the visceral mass of the animal rotates 180° to one side during development, such that the anus is situated more or less above the head. This ...

Facultative anaerobes use oxygen if it is available, but also have anaerobic methods of energy production. [7] Microaerophiles require oxygen for energy production, but are harmed by atmospheric concentrations of oxygen (21% O 2). [6] Aerotolerant anaerobes do not use oxygen but are not harmed by it. [6]
