A salp (pl.: salps, also known colloquially as “sea grape”) or salpa (pl.: salpae or salpas [2]) is a barrel-shaped, planktonic tunicate in the family Salpidae. It moves by contracting, thereby pumping water through its gelatinous body; it is one of the most efficient examples of jet propulsion in the animal kingdom. [3]
The slug mite, Riccardoella limacum, is known to parasitize several dozen species of mollusks, including many slugs, such as Agriolimax agrestis, Arianta arbustrum, Arion ater, Arion hortensis, Limax maximus, Milax budapestensis, Milax gagates, and Milax sowerbyi. Any use of beneficial organisms presents risks of new invaders or of disrupting ...
Scincus scincus, also commonly known as the sandfish skink, common sandfish or common skink, is a species of skink notable for its burrowing or swimming behaviour in sand. [2] It is native to the Sahara Desert and the Arabian Peninsula, [3] [4] but is also kept as a pet elsewhere. [5] [6]
The California mussel (Mytilus californianus) is a large edible mussel, a marine bivalve mollusk in the family Mytilidae. This species is native to the west coast of North America , occurring from northern Mexico to the Aleutian Islands of Alaska .
The blood of horseshoe crabs (as well as that of most mollusks, including cephalopods and gastropods) contains the copper-containing protein hemocyanin at concentrations of about 50 g per liter. [21] These creatures do not have hemoglobin (iron-containing protein), which is the basis of oxygen transport in vertebrates. Hemocyanin is colorless ...
To do so, they gathered up the debris underneath their bodies using their arms. They then used their siphon, a tube-like part of their body, to expel water aimed at the debris.
Mollusca is a phylum of protostomic invertebrate animals, whose members are known as molluscs or mollusks [a] (/ ˈ m ɒ l ə s k s /). Around 76,000 extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda . [ 5 ]
For these freshwater snails, the siphon is an anti-predator adaptation. It reduces their vulnerability to being attacked and eaten by birds because it enables the apple snails to breathe without having to come all the way up to the surface, where they are easily visible to predators. [6]
