Isolation
When environmental conditions change it is more likely that at least some members of a species will survive if there is variation among the members.
Automimicry is the advantage gained by some members of a species from their resemblance to others of the same species - such as various male species of bees and wasps which resemble more dangerous females.
There are several reasons why dozens of animal species become extinct daily. Some of these reasons include logging, and ranching. Taking away the animals habitat leaves them with no home an no source of food.
Vulnerable, or Threatened. Both mean that events could endanger the species because of habitat change, or because the population level is low enough to where they could be endangered if the loss of some of the population occurs.
there are tonnes of different species of salmon and yes some do live in salt water and you can fish them but some live in fresh water and you can fish them too.
Isolation
False.
They become members for more privileges.

A subspecies is a subgroup of a species that has inherent differences that make it distinct from the species as a whole. Subspecies can interbreed with other members of their species and the offspring remain fertile... Often created by genetic drift in a region that has become isolated from the "parent" species for some period of time.
Depends on species.
there is variation among the members.
Jellyfish development occurs in multiple phases. Sperm fertilize eggs which develop into larval planulae, become polyps, bud into ephyrae and then transform into adult medusae. In some species, specimens may skip some phases.

Some Species are better suited for the environment they are in. Say, if flood occurs in mountainous region, species that can swim are more likely to survive than animals that cannot.
A human gamete cannot fertilize an animal egg. Members of any animal species can only reproduce with other members of its own species, or in some cases with members of a very closely related species, and there is no species that is close enough to the human species to allow for cross breeding. Possibly when the Neanderthal species existed, it could have cross bred with H. sapiens, and maybe it did.
