The natural world is a difficult place. Animals’ lives may be tough as they face resource competition and sometimes unfriendly settings.
However, in order to live and overcome the odds, some creatures evolved in some rather unique and surprising ways.
Here are seven species that have evolved in bizarre ways to survive in their environments. And this is list down five adaptation that our species may develop in order to continue surviving on earth.
To survive the winter, up to 60% of the bodies of Alaskan Wood Frogs freeze solid. They also cease to breathe and their hearts cease to beat. They may live in temperatures as low as -80 degrees Fahrenheit because of this. They thaw out and “come back to life” in the spring.
To attain this semi-frozen condition, the organisms accumulate enormous amounts of glucose in their organs and tissues (up to ten times the usual amount). The sugar solutes act as “cryoprotectants,” preventing their cells from shrinking or dying.
Kangaroo rats have evolved to live in the desert without ever drinking water. Instead, they obtain all of their moisture from the seeds they ingest. These animals have excellent hearing and can leap up to nine feet, allowing them to dodge predators.
To live in the icy Southern Ocean that encircles Antarctica, five groups of notothenioid fish produce their own “antifreeze” proteins. The proteins in their blood bond to ice crystals, keeping the fish from freezing. This adaptation is so remarkable that it helps to explain why these fish account for 90 percent of the region’s fish biomass.
Cuttlefish have the incredible ability to alter color and texture to fit in with their environment. They can monitor how much light is absorbed in their surroundings and utilize that knowledge to imitate it with their own pigments.
They contain three skin layers (yellow, red, and brown) that may be stretched in various ways to create varied colors and patterns. Their skin also possesses papillae, which give cuttlefish the appearance of being stiff, like coral. These characteristics help cuttlefish to evade predators and sneak up on unsuspecting victims.
For a long time, scientists believed that life could not survive in hydrothermal vents deep in the ocean. However, in 1977, they discovered huge tubeworms dwelling 8,000 feet below the ocean’s surface along the Galapagos Rift. In their habitat, these tubeworms are completely dark, and they live in water containing toxic gas and acid.
These organisms lack a stomach, intestine, and eyes. They are instead “bags of bacteria” with heart-like structures and reproductive functions. The bacteria inside the worms use the toxic hydrogen sulfide in the water as an energy source to produce carbohydrates, which would kill most other animals.
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.
Adaptation can protect animals from predators or harsh weather conditions. Many birds can hide among thick grass and weeds, while insects may alter their colors to fit in. This makes it tough for predators to find them and feed on them.
Adaptations are classified into three types: Behavioural reactions are actions taken by an organism to help it live and reproduce. Physiological – a bodily process that aids an organism’s survival and reproduction. Structural – a feature of an organism’s body that aids in survival and reproduction.
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.
