how can you tell if two animals are in the same genus?

Please help! lol this is really stupid! but i need help in bio! haha

Update:

I really really need the answer to this quickly. Please! I need biology help! Thank you!!!!

Update 2:

there are a bunch of different pictures of sharks. and a couple look like sting rays.

the question is, "what characteristics should be very similar in order to support the prediction that two sharks are closely related?"

Update 3:

crap this thing is so annoying!

the other real question is "do any of the sharks appear to be in the same genus?"

sorry:/

Update 4:

The activity doesnt give you the names of the animals. After the activity is over, you then are told what the animals are.

    Pivotal in binomial nomenclature

    The generic name often is a component of the names of taxa of lower rank. For example, Canis lupus is the scientific name of the Gray wolf, a species, with Canis the generic name for the dog and its close relatives, and with lupus particular (specific) for the wolf (lupus is written in lower case). Similarly, Canis lupus familiaris is the scientific name for the domestic dog.

    Taxonomic units in higher ranks often have a name that is based on a generic name, such as the family name Canidae, which is based on Canis. However, not all names in higher ranks are necessarily based on the name of a genus: for example, Carnivora is the name for the order to which the dog belongs.

    [edit]The problem of identical names used for different genera

    A genus in one kingdom is allowed to bear a scientific name that is in use as a generic name (or the name of a taxon in another rank) in a kingdom that is governed by a different Nomenclature Code. Although this is discouraged by both the International Code of Zoological Nomenclature and the International Code of Botanical Nomenclature, there are some five thousand such names that are in use in more than one kingdom. For instance, Anura is the name of the order of frogs but also is the name of a genus of plants (although not current: it is a synonym); Aotus is the genus of golden peas and night monkeys; Oenanthe is the genus of wheatears and water dropworts, and Prunella is the genus of accentors and self-heal.

    Within the same kingdom one generic name can apply to only one genus. This explains why the platypus genus is named Ornithorhynchus — George Shaw named it Platypus in 1799, but the name Platypus had already been given to the pinhole borer beetle by Johann Friedrich Wilhelm Herbst in 1793. Names with the same form but applying to different taxa are called homonyms. Since beetles and platypuses are both members of the kingdom Animalia, the name Platypus could not be used for both. Johann Friedrich Blumenbach published the replacement name Ornithorhynchus in 1800.

    Look at the scientific names. If the first (capitalized) part of the name is the same, they are in the same genus.

    Which animals are you trying to tell for? If you give me an example, I might be able to help.

    They are very similar, but cannot breed together. For example, a catfish and a perch. Or a chimp and an orangutan.
