Depends what environment it is in.
Acquired traits.
Genetic traits that make organisms more likely to survive and reproduce in a particular environment include adaptations such as camouflaging, efficient metabolism, disease resistance, and reproductive strategies suited to the environment's challenges. These traits increase an organism's chances of successfully passing on its genes to the next generation, enhancing its overall fitness in that environment.
The key factor that determines which organisms with traits well suited to their environment survive and reproduce most successfully is natural selection. This process favors individuals with advantageous traits that help them adapt and thrive in their specific environment, increasing their chances of passing on these traits to future generations.
Whales, seals, and walruses have adapted to survive the Arctic cold through various physiological traits. They possess a thick layer of blubber that insulates their bodies against frigid temperatures. Additionally, their fur or skin helps retain heat, while specialized circulatory systems minimize heat loss. These adaptations enable them to thrive in the harsh Arctic environment.
Adaptations.
Adaptations.
"Fitness refers to an organism's capability to survive and reproduce in its environment. It is a measure of how well an individual's traits contribute to its reproductive success and overall survival."
Those features are called adaptations. Adaptations are traits or behaviors that help an organism survive and reproduce in its environment.

This process is known as natural selection, a mechanism proposed by Charles Darwin. Individuals with advantageous traits that allow them to survive and reproduce in their environment pass these traits on to their offspring, leading to a gradual evolution of a population better adapted to its surroundings.
antarctic seals have blubber to keep them warm.
