The capacity of a living thing to exist in a specific environment that quickly becomes its home is referred to as adaptation.
This is where they can gather enough food to consume, propagate their species, and keep themselves secure from any attacks.
These are critical for them to adapt and continue to exist as a species as part of the environment.
A structural adaptation is one that is physically part of the organism. An adaptation may also be behavioral, influencing how an organism reacts to its surroundings.
Some plants have evolved to living in dry, scorching deserts as an example of structural adaptation. Succulent plants, which store water in their short, thick stems and leaves, have adapted to this environment.
Behavioral adaptations include seasonal migration. Gray whales (Eschrichtius robustus) journey thousands of kilometers each year from the chilly Arctic Ocean to the warm waters off the coast of Mexico to spend the winter. Grey whale calves are born in warm southern seas and move in pods to the nutrient-rich waters of the Arctic.
Adaptations that arise in response to one challenge may assist with or be co-opted for another. Feathers were most likely the earliest adaptations for tactile sensing or temperature regulation. Later, feathers became longer and stiffer, enabling gliding and, eventually, flight. These characteristics are known as exaptations.
Some features, on the other hand, lose function when other adaptations take precedence or as the environment changes. Vestigial evidence of these features remains – diminished or functionless. Whales and dolphins contain vestigial leg bones, which are the remnants of an adaption (legs) that their forefathers used to walk.
Adaptations are often formed in reaction to a change in the organism’s environment.
The peppered moth of England is a well-known example of an animal adjusting to a change in its habitat (Biston betularia). Prior to the nineteenth century, the most prevalent hue of this moth was cream with darker markings. There were few gray or black peppered moths.
The peppered moth’s appearance altered as the surroundings changed throughout the Industrial Revolution. Darker-colored moths, which were formerly unusual, started to flourish in the urban environment.
Their smoky hue mixed nicely with the trees, which had been tarnished by industrial pollutants. Birds couldn’t see the black moths as well as they did the cream-colored moths, so they ate them instead. After the United Kingdom implemented regulations limiting air pollution, the cream-colored moths started to make a return.
Occasionally, an adaptation or group of adaptations emerges that divides a species into two. This is referred to as speciation.
Marsupials in Oceania are an example of adaptive radiation, a kind of speciation in which species evolve to fit a wide range of ecological niches. Marsupials, which are mammals that carry their growing young in pouches after a brief pregnancy, arrived in Oceania before the continent separated from Asia.
Every other continent was dominated by placental mammals, animals that bring their young to term in the mother’s womb, save Oceania. Koalas (Phascolarctos cinereus), for example, have evolved to graze on eucalyptus trees unique to Australia. The extinct Tasmanian tiger (Thylacinus cynocephalus) was a carnivorous marsupial that adapted to the niche occupied by large cats on other continents, such as tigers.
Cichlid fish, which may be found in many African lakes, demonstrate another kind of speciation known as sympatric speciation. Physical isolation is the inverse of sympatric speciation. It occurs when two or more species share the same environment.
Adaptations have enabled hundreds of cichlid species to thrive in Lake Malawi. Each cichlid species has a distinct, specialized diet: one cichlid may consume exclusively insects, another algae, and still another other fish.
Creatures sometimes adapt alongside and to other organisms. This is known as coadaptation. Hummingbirds are drawn to blooms that yield nectar. Hummingbirds, on the other hand, have evolved long, narrow beaks to harvest nectar from certain flowers.
When a hummingbird visits a flower to eat, it mistakenly takes up pollen from the anthers, which is then deposited on the stigma of the next flower it visits. The hummingbird benefits from this association, while the plant benefits from pollen distribution. Both creatures benefit from coadaptation.
Another sort of coadaptation is mimicry. One creature has developed to resemble another via mimicry. The innocuous king snake (also known as a milk snake) has developed a color pattern that mimics that of the dangerous coral snake. The king snake’s mimicry keeps predators at bay.
The mimic octopus (Thaumoctopus mimicus) possesses morphological and behavioral adaptations. This octopus can mimic the appearance and motions of other creatures such as sea snakes, flatfish, jellyfish, and shrimp.
Coadaptation may also impair an organism’s capacity to adapt to new environmental changes. This may result in co-extinction. The giant blue butterfly adapts to eating red ants in southern England.
When human development restricted the habitat of red ants, the local extinction of the red ant resulted in the local extinction of the huge blue butterfly.
Many animals have created particular body components tailored to life in a given habitat. Webbed feet, sharp claws, whiskers, sharp fangs, big beaks, wings, and hooves are among them. Swimming is essential for most aquatic species.
Structural Adaptation Examples

Giraffes’ long necks allow them to access food high up in trees that other animals cannot reach.

Adaptations are distinct features that enable creatures to survive in their surroundings. Adaptations are classified into three types: structural, physiological, and behavioral.
Natural selection causes this to happen. Natural selection progressively modifies the nature of the species to become more fitted to the niche. If a species becomes very well adapted to its surroundings and the environment does not change, it may persist for a very long period before becoming extinct.
