Birds, especially those that fly, have lightweight and hollow (pneumatic) bones to reduce body weight and make flight easier. While their bones are structurally strong for their weight, they are less dense compared to those of land animals.

Like birds, bats have lightweight bones to aid in flight. Their bones are more fragile and less dense than those of non-flying mammals.

Many amphibians, such as frogs and salamanders, have relatively less dense bones. This adaptation helps them stay buoyant in water and move easily on land.

Certain reptiles, such as snakes, have less dense bones. Their skeletal structure is adapted for flexibility and movement rather than strength.

Some fish, especially those in the deep sea, have lighter, less dense bones. This adaptation helps them conserve energy and maintain buoyancy in the deep ocean.

Some small mammals, like certain species of shrews and bats, have relatively weaker bones compared to larger mammals. Their bones are adapted for agility and speed rather than strength.

While not strictly "bones," many invertebrates have exoskeletons or minimal internal skeletal structures made of materials that are not as strong as the bones of vertebrates. Examples include insects and crustaceans.
