State three differences between animals on land and animals on water
1) Habitat: Animals on land, such as mammals and reptiles, have adapted to survive in terrestrial habitats, which consist of a solid surface and limited water availability. This includes adaptations such as lungs for breathing air and specialized limbs for terrestrial locomotion. In contrast, animals in water, such as fish and marine mammals, have evolved to live in a fluid environment, with adaptations like gills for extracting oxygen from water and streamlined bodies for efficient swimming.
2) Movement: Animals on land typically move by walking, running, crawling, or jumping, using their limbs for locomotion. On the other hand, animals in water have diverse modes of movement, including swimming, floating, and gliding. Aquatic animals may use fins, flippers, or undulating body movements to propel themselves through the water.
3) Sensory adaptations: Due to the distinct environments they inhabit, animals on land and in water have different sensory adaptations. Land animals often have well-developed senses of smell, sight, and hearing, as these are crucial for finding food, detecting predators, and identifying potential mates in their environment. For aquatic animals, their sensory systems are typically specialized for underwater life. Some marine creatures have highly sensitive eyes adapted to low light conditions, while others rely primarily on senses like echolocation or lateral lines to navigate and locate prey in water, as visibility may be reduced.
