List of sharks

List of sharks is a biology 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 List of sharks rather than just read about it. In short: Shark is the naming term of all members of Selachimorpha suborder in the subclass Elasmobranchii, in the class Chondrichthyes. The Elasmobranchii also include rays and skates; the Chondrichthyes also include Chimaeras.

Key takeaways

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

Reference excerpt

Shark is the naming term of all members of Selachimorpha suborder in the subclass Elasmobranchii, in the class Chondrichthyes. The Elasmobranchii also include rays and skates; the Chondrichthyes also include Chimaeras. The first shark-like chondrichthyans appeared in the oceans 400 million years ago, developing into the crown group of sharks by the Early Jurassic. Listed below are extant species of shark. Sharks are spread across 557 described and 23 undescribed species in eight orders. The families and genera within the orders are listed in alphabetical order. Also included is a field guide to place sharks into the correct order.

Cow and frilled sharks (2 Families) ORDER HEXANCHIFORMES Family Chlamydoselachidae (frilled sharks) Genus Chlamydoselachus Garman, 1884 Chlamydoselachus africana Ebert & L. J. V. Compagno, 2009 (Southern African frilled shark) Chlamydoselachus anguineus Garman, 1884 (frilled shark) Family Hexanchidae (cow sharks) Genus Heptranchias Rafinesque, 1810 Heptranchias perlo (Bonnaterre, 1788) (sharp-nose seven-gill shark) Genus Hexanchus Rafinesque, 1810 Hexanchus griseus (Bonnaterre, 1788) (blunt-nose six-gill shark) Hexanchus nakamurai Teng, 1962 (big-eyed six-gill shark) Hexanchus vitulus Springer and Waller, 1969 (Atlantic six-gill shark) Genus Notorynchus Ayres, 1855 Notorynchus cepedianus (Péron, 1807) (broad-nose seven-gill shark)

Worked examples

Example 1 — a first encounter with List of sharks

Start with the simplest possible case. Write down what List of sharks claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 List of sharks 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 List of sharks 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 List of sharks

In research
List of sharks appears in biology 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 List of sharks 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
List of sharks is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lists of fishes, Sharks, Taxonomic lists (species), so understanding it makes those chapters shorter.
In everyday life
Look for List of sharks 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.
