    An animal (plural: animals) refers to any of the eukaryotic multicellular organisms of the biological kingdom Animalia. Animals of this kingdom are generally characterized to be heterotrophic, motile, having specialized sensory organs, lacking a cell wall, and growing from a blastula during embryonic development. Etymology: Latin animale (neuter of...

    An animalpertains to any of the eukaryotic multicellular organisms that comprise the biological kingdom of Animalia. Animals possess several characteristics that set them apart from other forms of life. Some of their general characteristics are as follows: 1. Animals are multicellular organisms. The animal body is composed of several cells performi...

    Most animals (at least 99%) have a bilaterally symmetric body plan. When the body is divided by a sagittal plane, the result is having two sides with roughly mirror images, at least morphologically. Most animals are sexually dimorphic,i.e. males and females exhibit different characteristics aside from the differences in their sex organs. For exampl...

    The life cycles in the animal kingdom are diverse. For brevity, the four fundamental stages are infancy » young » adulthood » senescence. All animals undergo these stages in their life cycle. Most mammals have a life cycle that is simple and straightforward. Nevertheless, there are animals whose life cycles are rather complex. Amphibians, like frog...

    Animals are an important part of the ecological system. They form intricate food webs. They interact with other organisms and form various symbiotic relationships, e.g. mutualism, predation, competition, commensalism, and parasitism. Some animals demonstrate altruistic (self-sacrificing) behavior for the benefit of their conspecifics or colonies. T...

    The evolution of life on Earth would lead to the common ancestor, LUCA(last universal common ancestor), presumed to have emerged some 3.5 to 3.8 billion years ago. It is the hypothetical ancestor of all living things, including animals. Here’s a brief timeline of the evolution of animals is shown below: 1. Proterozoic eon » Neoproterozoic era » Edi...

    In 1758, Carl Linnaeus created a biological classification system for animals. In 1874, Ernst Haeckel proposed to divide the animal kingdoms into two groups: the multicellular Metazoa and the single-celled Protozoa. Later, the protozoans were no longer considered animals and have been designated with their own biological kingdom. At present, the ki...

    Animals have long been a key player in the ecosystem and performing an essential role in the lives of other organisms whether from the same kingdom or not. For instance, the carbon dioxide that the animals breathe out is essential to plants and other autotrophs as it is a reactant in the early steps of photosynthesis. Animals have also a great impa...

    The branch of science that deals with animals is zoology. The topics are varied. Some of the areas of study are morphoanatomy, histology, physiology, ecology, evolution, taxonomy, and ethology. Specific groups of animals being studied also led to sub-disciplines such as entomology (the study of insects), herpetology (the study of amphibians and rep...

  2. Oct 4, 2019 · The generic epithet of binomial nomenclature refers to the taxonomic hierarchy of organisms, genus, of each organisms. This is a clue as to the origins, evolution, and life-history of the organism. Genera, which reside in families, share the traits of those families. In turn, families reside within orders, which also have their own characteristics.

If this changes, the animals can interbreed, and may merge into one species. This is currently being seen in the wild in polar bears and grizzly bears.

  4. Jul 12, 2022 · One can also go more into depth about the structure and reproduction and growth characteristics of animals. Kingdom Animalia is a taxonomic kingdom of living and extinct animals. Members of this kingdom are characterized by being eukaryotic, multicellular, heterotrophic, lacking a cell wall, and mostly are motile.

  5. Animal species are often split into vertebrates and invertebrates – two very broad categories of animals. Vertebrate species are animals that do have a backbone such as humans, birds, fish and reptiles and make up the majority of large land animals. Invertebrate animals lack a backbone and often have a skeleton on the exterior of the body.
