A microscope (from the Greek: μικρός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope. There are many types of microscopes, the most common and first to be invented is the optical microscope which uses light to image the sample...

A kitten is a juvenile domesticated cat. A feline litter usually consists of two to five kittens. To survive, kittens need the care of their mother for the first several weeks of their life. Kittens are highly social animals and spend most of their waking hours playing and interacting with available companions. Etymology The word "kitten" derives from Middle English kitoun (ketoun, kyton etc.), which itself came from Old French chitoun, cheton: "kitten"...

Litter consists of waste products such as containers, papers, and wrappers which have been disposed of without consent. Litter can also be used as a verb. To litter means to throw litter onto the ground as opposed to disposing it properly. Throughout human history, people have disposed of unwanted materials onto streets, countrysides and remote places, unpunished. Prior to reforms within cities in the mid to late 1800s, sanitation was not a priority on governments' lists of things to do...

A hedgehog is any of the spiny mammals of the subfamily Erinaceinae and the order Erinaceomorpha. There are 17 species of hedgehog in five genera, found through parts of Europe, Asia, Africa, and New Zealand. There are no hedgehogs native to Australia, and no living species native to North America; those in New Zealand are introduced. Hedgehogs have changed little over the last 15 million years. Like many of the first mammals they have adapted to a nocturnal, insectivorous way of life...

Meet Mumble - the confused chicken in China who thinks it's a penguin. Instead of scratching in the ground and roosting on a perch at night, Mumble waddles from side to side. The chicken has been nicknamed Mumble after the lead character in Happy Feet. Farmer Lu Xi got the bird as a chick, reports CEN. "He only has little wings, just like a penguin, which he sticks out when he walks. I guess that’s why he never flies," he said...

A 38-year old photographer Andrey Nekrasov took these amazing photos of divers swimming with beluga whales underneath the ice of White Sea. The beluga or white whale (Delphinapterus leucas) is an Arctic and sub-Arctic species of cetacean. It is one of two members of the family Monodontidae, along with the narwhal. This marine mammal is commonly referred to simply as the beluga or sea canary due to its high-pitched twitter...

Gulls (often informally called seagulls) are birds in the family Laridae. They are most closely related to the terns (family Sternidae) and only distantly related to auks, skimmers, and more distantly to the waders. Until recently, most gulls were placed in the genus Larus, but this arrangement is now known to be polyphyletic, leading to the resurrection of several genera. Gulls are typically medium to large birds, usually grey or white, often with black markings on the head or wings...

Marine biology is the scientific study of organisms in the ocean or other marine or brackish bodies of water. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. Marine biology differs from marine ecology as marine ecology is focused on how organisms interact with each other and environment and biology is the study of the animal itself...
