To ensure its survival, any species must be able to

Adapt

Explanation:

According to Charles Darwin, there is a constant struggle for species survival, in which individuals best adapted to their environment (not necessarily the strongest) are able to survive and continue the species.

Example: In a snowy environment, white fur mammals are more difficult to find by their predators than black fur mammals.

Therefore, these will have a higher survival rate, and consequently a higher reproduction rate. Then, over time, the population of white fur mammals will outnumber the black fur population.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
