MollusksAny animal belonging to the phylum Mollusca is classified as a mollusk, regardless of its class, order, or species. Mollusks mainly inhabit marine environments. They all have a specialized structure called the mantle.Answer and Explanation: ...
The slug's trunk ends in a mucus pore, which is usually clogged with mucus. Inside the trunk under the portion covered by the left side of the mantle isits heart. The heart has just two chambers (we have four!) ... This means slugs possess both male and female organs. Are all shel...
A tunic is a simple, often sleeveless garment that extends from shoulders to knees, used in various ancient and modern contexts. A mantle, on the other hand, is a loose, outer cloak worn over other clothes, often signifying status or used for warmth. ...
mollusk, also spelled mollusc, any soft-bodied invertebrate of the phylum Mollusca, usually wholly or partly enclosed in a calcium carbonate shell secreted by a soft mantle covering the body. What makes mollusks unique? All molluscs also have gills, a mouth and an anus. A feature unique to m...
There are two main ways to define the lithosphere. The geological definition is the part of Earth including the crust and extending down into part of the mantle, sometimes up to 120 miles down. Another is as part of the four spheres of Earth. The atmosphere, hydrosphere and biosphere are ...
Some species of mussels live in the hydrothermal vents that are found in deep ocean ridges. Their shells can be brown, dark blue or black; inside, they are silvery. A mussel's byssal thread can be used as a defense mechanism to capture predatory mollusks that attack mussel beds. ...
Phylum Mollusca - Mollusks are found in aquatic and terrestrial environments are characterized by a soft body (some have a hard shell protecting the body). The body of these organisms (the majority of mollusks) consists of several key features that include a muscular foot, mantle, and the ...
tiny eyes along the edge of the mantle lining their shells. The complexities of these mollusk eyes are still being unveiled. A newstudypublished inCurrent Biologyreveals that scallop eyes have pupils that dilate and contract in response to light, making them far more dynamic than pr...
Clams also have another method for obtaining nutrition, too. Some species of clams develop a symbiotic relationship with algae, such aszooxanthellae. These algae live in the mantle of the clams. While the mollusk takes in and feeds the algae the nitrogen it needs to thrive, the algae provide...
Sponges and cnidarians are two of the animal phyla that lack bilateral symmetry. Sponges are considered the simplest animals with the lowest degree of cellular specialization. Cnidarians have two true tissue layers that form during embryonic development, whi...
