Squirrel monkeys are not primates; they belong to the family Cebidae, which includes capuchin monkeys and howler monkeys.

Peacocks, specifically male peacocks, are renowned for their elaborate courtship displays, fanning their long, iridescent tail feathers to attract mates.

The African elephant holds the title of the largest land mammal, with males weighing up to 13,000 pounds and standing over 13 feet tall.

Orcas, also known as killer whales, are highly intelligent and social marine mammals, often traveling in pods and displaying complex hunting strategies.

Natural selection is the driving force behind evolution, where organisms with traits that enhance their survival and reproduction are more likely to pass those traits to offspring.

Bats and birds, despite having different evolutionary origins, both possess wings for flight, a remarkable example of convergent evolution.

Extinction refers to the complete disappearance of a species from the Earth, leaving no living members.

Deforestation, the clearing of forests for various purposes, is a major contributor to habitat loss and the decline of biodiversity.

Ecology is the branch of biology that examines the relationships between organisms and their environment, including their interactions with other organisms and the physical world.

Sea otters are keystone species because they prey on sea urchins, preventing them from overgrazing kelp forests, which in turn supports a diverse array of marine life.

Speciation is the process by which populations of a species diverge and become reproductively isolated, leading to the formation of new, distinct species.

Sharks and remoras have a mutualistic relationship; remoras attach themselves to sharks for protection and access to food, while sharks benefit from the remoras' cleaning services.

Migration is the movement of organisms from one habitat to another, often in response to seasonal changes or resource availability.

All of the listed species, including the Giant Panda, Blue Whale, African Elephant, and Polar Bear, are classified as threatened due to various factors such as habitat loss, poaching, and climate change.

Adaptation is the process by which organisms change their behavior or physiology to better suit their environment, increasing their chances of survival and reproduction.
