Belonging to the Peramelemorphia order, which also includes the bilby, bandicoots encompass approximately 20 different species. Their conservation status varies across these species.

Barn Owl

Scientifically known as Tyto alba, the barn owl is a bird belonging to the Tytonidae family. It is a widely distributed species, inhabiting various habitats across all continents except for Antarctica. With its white appearance, the barn owl derives its scientific name from the Latin word “alba,” meaning white.

What sets the barn owl apart, like other owls, is its ability to fly silently due to its specially adapted feathers. This species relies heavily on sound for hunting, utilizing its exceptional hearing to locate prey.

When it comes to diet, the barn owl primarily feeds on small mammals such as voles and shrews, which make up about 90% of its food intake. Additionally, it also hunts birds, other small vertebrates, and insects.


Arthropods of the Maxillopoda class and Cirripedia subclass, barnacles are peculiar creatures that inhabit oceans across the globe. Unlike most animals, barnacles undergo an initial larval stage before settling down for their entire adult lives, firmly attached to a single surface. Their remarkable adhesive abilities stem from the secretion of the strongest natural glue known to exist.

With a vast diversity of over 1,400 species, barnacles can be found in various corners of the world’s oceans. Among them, acorn barnacles are the most prevalent, thriving in temperate and tropical saltwater environments.

As omnivores, barnacles rely on their feather-like appendages known as “cirri” to capture and consume microscopic organisms that drift through the water. They skillfully filter these minuscule life forms for sustenance.

Barnacles made their debut over 300 million years ago, during the Carboniferous Period of the Paleozoic Era, marking a fascinating presence in Earth’s history.


Species of the fish family Sphyraenidae, barracudas are formidable predators inhabiting tropical and subtropical waters across the globe. With sleek, elongated bodies and impressive jaws, these saltwater fish belong to the genus Sphyraena and encompass a total of 28 distinct species. Some barracudas can reach lengths exceeding 1.5 meters (5 feet) and achieve remarkable swimming speeds of up to 35 mph (56 km/h).

Utilizing their exceptional agility and strength, barracudas rely on their swift movements to secure their primary source of sustenance: other fish. Their diet predominantly consists of fellow aquatic creatures, as they assert their predatory dominance in the underwater realm.

Basking Shark

Officially known as Cetorhinus maximus, the basking shark belongs to the fish family Cetorhinidae. This fascinating creature can be found in temperate waters across the globe. Sadly, its conservation status is endangered, highlighting the need for protective measures.

The basking shark claims the title of the world’s second largest fish, with only the whale shark surpassing it in size. Unlike most sharks that actively pursue prey, the basking shark follows a different approach. Similar to its larger counterpart, it is a filter feeder. While gracefully swimming, the basking shark simply opens its mouth wide. Within its mouth, it possesses comb-like structures called “gill rakers,” which act as filters. These gill rakers efficiently sift through the seawater, capturing tiny food items like zooplankton.

Bat-Eared Fox

Scientifically known as Otocyon megalotis, the bat-eared fox is a mammal belonging to the Canidae family. It can be found roaming the grasslands of Africa, specifically in the sub-Saharan regions. With its characteristic large ears, similar to the fennec fox and kit fox, which also inhabit arid or desert environments, the bat-eared fox serves a dual purpose. Its prominent ears aid in dissipating body heat, keeping the fox cool, while also assisting in locating its prey.

What sets the bat-eared fox apart is its unique diet as the only canid species with a preference for insects. Its primary source of sustenance is the harvester termite. This remarkable fox is divided into two distinct populations, one residing in southern Africa and the other in western Africa.


Bats, fascinating mammals with the ability to fly, belong to the order Chiroptera. They can be found on every continent except Antarctica, showcasing their widespread presence. With approximately 1,400 different bat species, Chiroptera stands as the second-largest order of mammals. Remarkably, bats comprise nearly a quarter of all existing mammal species.

To put this in perspective, the largest mammalian order, Rodentia, which encompasses rodents, accounts for approximately 40% of the total mammal population.

Bats are typically categorized into two primary types: Megachiroptera, also known as megabats or fruit bats, primarily feed on fruits and nectar. On the other hand, Microchiroptera, referred to as microbats or echolocating bats, mainly rely on insects for their diet. What sets them apart is their unique wing structure, supported by elongated finger bones, enabling them to take flight.


Category: Mammals Family: Ursidae Habitat: Found across all continents except Antarctica Conservation status: Diverse

The Ursidae family comprises eight distinct bear species: polar bears, brown bears, American black bears, spectacled bears, Asian black bears, sloth bears, sun bears, and giant pandas. These remarkable creatures are characterized by their size and strength. While bears generally have omnivorous feeding habits, the specific dietary preferences vary among species. For instance, polar bears are predominantly carnivorous, whereas giant pandas primarily consume plant matter.


Species: Beavers Scientific Genus: Castor Animal Type: Mammal Family: Castoridae Habitat: North America, Europe Conservation Status: Least Concern

Beavers, belonging to the genus Castor, are remarkable mammals characterized by their size and distinctive tails resembling paddles. There are two known species of beavers: the North American beaver (Castor canadensis) inhabiting the United States and Canada, and the Eurasian beaver (Castor fiber) found across various regions in Northern Europe.

Both species of beavers have a conservation status of “Least Concern,” indicating that they are not currently threatened.

These resourceful creatures utilize their sharp teeth to fell trees and create dams. The resulting ponds serve not only as a defense against predators but also foster the development of wetland ecosystems, providing a habitat for numerous other species.

Due to their vital role in shaping and maintaining their respective ecosystems, beavers are considered keystone species.


Belonging to the Apoidea superfamily, bees are remarkable insects found across all continents except Antarctica. They share their superfamily with certain species of wasps, while also being closely related to ants. Together, these insects form the Hymenoptera order.

With a staggering number of over 16,000 species, bees encompass a diverse group including honey bees, bumblebees, stingless bees, and carpenter bees. Many bees exhibit a social lifestyle, residing in colonies led by a single queen responsible for laying eggs for the entire community.

Having evolved alongside flowering plants during the Cretaceous Period, bees play a crucial role as pollinators in terrestrial ecosystems. Their significance cannot be overstated, as they contribute to the survival and growth of numerous plant species. It is often quoted, possibly attributed to Einstein, that “If the bee disappeared from the surface of the Earth, man would have no more than four years left to live.”


Insects known as beetles belong to the order Coleoptera. They can be found on every continent except Antarctica. With an impressive number of approximately 400,000 recognized species, Coleoptera stands as the largest animal order in the world. Remarkably, beetles account for approximately 25% of all known animal species!

One fascinating adaptation of beetles is the presence of forewings that have evolved into hardened cases called elytra. These elytra serve as protective shields when beetles navigate through challenging terrains that could potentially harm the delicate wings of other insect species.

Among the familiar types of beetles are fireflies, dung beetles, glowworms, ladybugs (also known as ladybirds), Hercules beetles, tiger beetles, and weevils.
