Final answer:
Adaptations found in penguins, snails, polar bears, and elephants are respectively thick blubber and flippers, protective shell and mucus secretion, fur and fat insulation with large swimming paws, and large ears, a long trunk, and thick skin for various environmental challenges.
Step-by-step explanation:
The adaptations found in various animals are specific to their environments and lifestyles. Here is a list of adaptations for the given animals:
- Penguins have adapted to cold environments with their thick layer of blubber and feathers that provide insulation. They also have flippers for efficient swimming in water to catch fish.
- Snails have a hard shell that provides protection from predators and environmental elements. Their muscular foot secretes mucus to aid in their slow movement across surfaces.
- Polar bears have thick fur and a layer of fat that insulates them from the frigid Arctic climate. They are also excellent swimmers, with large paws that help them navigate through water and over ice to hunt for seals.
- Elephants have large ears that help with thermoregulation, a long trunk for feeding and drinking, and thick skin to protect from the sun and parasites.
These adaptations are critical for the survival of these animals in their respective habitats.
