A feature shared by all animals:

Explanation

All animals are heterotrophs, which means they rely on consuming other organisms for nutrition. This is a fundamental trait that distinguishes them from autotrophs, like plants, which can produce their own food through photosynthesis. The other options are not universal among animals: some animals, such as sponges, are sessile and not motile; animals inhabit both aquatic and terrestrial environments, so an aquatic lifestyle is not a shared trait; and not all animals have limbs, as many invertebrates move in other ways.
