Answers
1. ⚫Coming to aerial habitat, aerial habitats are those which are found in the sky. Therefore, examples of animals living in aerial habitat are - Birds, insects, etc.
The animals belonging to aerial habitat have the following characteristics,
>They have wings to help them fly
>Their body and wings are covered with feather or silky membrane
>They are made up of light and hollow bones in order to assist in flying
>They spend most of their life in air
>They catch insects/ prey while flying.
⚫A claw is a curved, pointed appendage found at the end of a toe or finger in most amniotes (mammals, reptiles, birds). Some invertebrates such as beetles and spiders have somewhat similar fine, hooked structures at the end of the leg or tarsus for gripping a surface as they walk. The pincers of crabs, lobsters and scorpions, more formally known as their chelae, are sometimes called claws.
⚫The beak, bill, and/or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs, and a few mammals. A beak is used for eating, preening, manipulating objects, killing prey, fighting, probing for food, courtship, and feeding young. The terms beak and rostrum are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a beak-like structure), sirens, pufferfish, billfishes and cephalopods.
Answer:
• Aerial animals are those that can soar, fly or glide naturally in the air.
• A bird's talons are the sharp, hooked claws at the end of the toes. Birds have one talon on every toe, and they may differ in overall shape, curvature, and thickness depending on how the bird will use its talons and how worn individual talons may be.
