Triops longicaudatus, a crustacean often referred to as a type of tadpole shrimp, is found in various freshwater bodies, especially temporary pools, in North America, South America, the Caribbean, Japan and some Pacific Islands.
At the very least, all viruses contain two components: the capsid (a protein shell), and a genome, consisting of either DNA or RNA. Some viruses also include accessory proteins to aid in infection, or a lipid bilayer to further protect their contents from the environment.atellite viruses are some of the smallest possible reproducing units in nature; they achieve this by relying on both the host cell and a host virus (in this case, TMV) for the machinery necessary for them to reproduce.
A virus is basically a tiny bundle of genetic materialâeither DNA or RNAâcarried in a shell called the viral coat, or capsid, which is made up of bits of protein called capsomeres. Some viruses have an additional layer around this coat called an envelope. That's basically all there is to viruses.
