Lists of animals

Lists of animals is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lists of animals rather than just read about it. In short: Animals are multicellular eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development.

Key takeaways

  • Lists of animals belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Lists of animals to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Lists of animals from memory before moving on to harder problems.

Reference excerpt

Animals are multicellular eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs. The study of animals is called zoology. Animals may be listed or indexed by many criteria, including taxonomy, status as endangered species, their geographical location, and their portrayal and/or naming in human culture.

Phyla

The animal Kingdom contains some 35 extant phyla. Basal animals are delineated according to the following cladogram:

Animals: Porifera, Diploblasts Diploblasts: Ctenophora, ParaHoxozoa ParaHoxozoa: Placozoa, Cnidaria, Bilateria/Triploblast Bilateria: Xenacoelomorpha, Nephrozoa Nephrozoa: Protostomes, Deuterostomes

Phylum Proarticulata† Disputed if this is in or out of Bilateria and Phylum Xenacoelomorpha is basal

Worked examples

Example 1 — a first encounter with Lists of animals

Start with the simplest possible case. Write down what Lists of animals claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lists of animals before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lists of animals ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lists of animals

In research
Lists of animals appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Lists of animals in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Lists of animals is common in secondary-school and first-year university syllabi. It links to neighbouring topics Animals, Lists of animals, so understanding it makes those chapters shorter.
In everyday life
Look for Lists of animals outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
