Study Notes

Nocturnal Animals

Nocturnal animals are active at night and sleep during the day.
Examples include hedgehogs, foxes, owls, bats, and aardvarks.
Adaptations for nighttime activity include excellent hearing, sight, and smell.

Hibernation

Hibernation is a period of deep sleep during winter.
Animals' metabolism, breathing rate, heart rate, and body temperature slow down.
Hibernation allows animals to conserve energy during periods of scarce food and cold temperatures.

Bird Adaptations for Flight

Birds have adaptations for flight including light bodies, wingshaped wings, speed and strength.
Birds use different methods to take off, including running, leaping, or fast flapping.
Flight occurs when air pressure above the wing is greater than the pressure below, enabling them to overcome gravity.

Fossils

Fossils are remains or traces of ancient plants and animals.
Two types of fossils include:
- Body fossils: remains of plants or animals.
- Trace fossils: evidence of animal activity.
Fossils are usually found in sedimentary rock.
Common locations for fossil discoveries include North and South America, Asia and others.
Fossils are found in various forms, including those encased in amber or coprolite(fossilized animal poop).

Eagles

Eagles are large carnivorous birds.
They have sharp beaks and talons.
Eagles eat animals like squirrels, rabbits, and fish.
Eaglets hatch from eggs after six weeks of incubation.

Endangered Pandas

Pandas are endangered due to several factors including difficulty reproducing, poor bamboo diet, habitat loss, and poaching.
Zoos and reserves are working to protect pandas.

Panda Habitat

Pandas are black and white bears native to the high mountains of central China.
Their primary habitat is bamboo forests.
Pandas rely almost entirely on bamboo for food and water.
Their habitat used to be in the lowlands but they migrated to the mountains due to human activity.

Endangered Tigers

Tigers are endangered due to poaching (hunting for body parts), habitat loss, and negative human relations.
Worldwide efforts are underway to conserve tigers.

Endangered Indian Animals

Several animal species in India are endangered or critically endangered due to poaching, habitat loss, pollution and other factors.
Examples include the Bengal tiger, gharial, red panda, great Indian bustard, blackbuck, Indian wild dog, and pangolin.

Black Panthers

Black panthers are big cats with black fur, primarily jaguars and leopards.
The agouti gene controls black fur pigmentation.
Black fur does not impair hunting abilities.

Polar Bear Life Cycle

Polar bear babies are called cubs.
Litter sizes can range from one to three.
Cubs stay with their mothers for several years before becoming independent.
Adult polar bears can live 15-18 years in the wild.

Fish Anatomy

Fish have many body parts that facilitate survival in water.
Fins (dorsal, pectoral, pelvic, and caudal) aid in swimming.
Gills extract oxygen from water.
Scales provide protection.

Skeletal Systems

Two types exist: exoskeletons (external) and endoskeletons (internal).
Both protect and support the body, though their composition and location differ.

Dinosaurs and Pterosaurs

Dinosaurs did not fly or swim.
Pterosaurs, flying reptiles, lived during the same period as dinosaurs.
They had skin wings and ate fish, reptiles and squid.

Animal Reproduction

Many animals hatch from eggs, amphibians, reptiles and fish.
Some mammals lay eggs and some have live births..
