The existence of this pocket shows even in an empty shell, as a visible indentation in the pallial line, a line which runs along parallel to the ventral margin of the shell. [10] The bivalve's two siphons are situated at the posterior edge of the mantle cavity. [11] There is an inhalant or incurrent siphon, and an exhalant or excurrent siphon. [12]
These snails are sometimes viewed as pests in aquarium tanks with fish, because the snails create waste, reproduce very often, and are very hard to remove completely. However, some aquarium owners deliberately choose to add these freshwater pond snails to their tank because the snails will eat uneaten fish food, algae and waste, as well as ...
In certain groups of carnivorous snails, where the siphon is particularly long, the structure of the shell has been modified in order to house and protect the soft structure of the siphon. Thus the siphonal canal is a semi-tubular extension of the aperture of the shell through which the siphon is extended when the animal is active.
Pomacea bridgesii, common name the spike-topped apple snail or mystery snail, is a South American species of freshwater snail with gills and an operculum, an aquatic gastropod mollusk in the family Ampullariidae. These snails were most likely introduced to the United States through the aquarium trade.
Freshwater snails are commonly found in aquaria along with tropical fish. Species available vary in different parts of the world. In the United States, commonly available species include ramshorn snails such as Planorbella duryi , bladder snails such as Physella acuta , apple snails such as Pomacea bridgesii , the high-spired thiarid Malaysian ...
In most aquarium tanks, the fish are at high concentrations and the volume of water is limited. This means that communicable diseases can spread rapidly to most or all fish in a tank. An improper nitrogen cycle , inappropriate aquarium plants and potentially harmful freshwater invertebrates can directly harm or add to the stresses on ornamental ...
A leaking drain hose in the reach-in cold unit with deli meats and cheeses dripped “directly on an open package of ham stored in the unit.” A Stop Sale dripped on the ham, which got tossed.
The red-rimmed melania (Melanoides tuberculata), [3] [4] also known as Malayan livebearing snails or Malayan/Malaysian trumpet snails (often abbreviated to MTS) by aquarists, is a species of freshwater snail with an operculum, a parthenogenetic, aquatic gastropod mollusk in the family Thiaridae.
