Mandibular/nasal barbells and gill rakers can help distinguish between various fish. Countershading, tail shape (forked/lunate), and environment can be useful too.

[57] As well as controlling some muscles and body organs, in bony fish at least, the brain stem governs respiration and osmoregulation. [57] Caudal fin– The tail of the fish can be forked, lunate, or rounded. Its length, shape, coarseness, upper and lower lobe all vary.

The caudal fin, or tail fin, has an upper and lower lobe. These vary in size and position. The shape and position of the lobes, and the presence of a lower lobe or fork, can help to identify fish. In the world of fishing, correctly identifying the species of fish you’ve caught is essential for ethical and legal reasons. While there are a variety of methods to identify various species, focusing on their fins and tail shape can often be one of the most efficient and reliable. This section will explore the ins and outs of identifying fish species through their fins and tail shape, starting with the anatomy of fish fins and types of fins and their functions. We will then delve into identifying fish species by their:

FAQs about How To Identify Fish Species By Their Fins And Tail Shape 1. How can I tell the difference between fish species based on their fin and tail shape?

Ichthyosaurs are ancient reptiles that resembled dolphins. They first appeared about 245million years ago and disappeared about 90million years ago. Four types of scales are present: cycloid, ctenoid, ganoid, and cosmoid. Cycloid and ctenoid scales help measure the standard fish length for identification.

Perch and other species have forked caudal fins.

Aristotle, De incessu animalium [74] Comparison between A) the swimming fin of a lobe-finned fish and B) the walking leg of a tetrapod. Bones considered to correspond with each other have the same color. In a parallel but independent evolution, the ancient reptile † Ichthyosaurus communis developed fins (or flippers) very similar to fish (or dolphins). Tail Shape– This is determined by the shape of its caudal fin. Different shapes help distinguish fish species. For example, in India, Rohu and Mrigal have differing caudal fin shapes and lateral line scales. A study suggests head and eye length help differentiate between scaled fish and non-scaled catfish. The number of dorsal fin rays and branchiostegeal ray can also help.D) - Diphycercal means the vertebrae extend to the tip of the tail and the tail is symmetrical and expanded (as in the bichir, lungfish, lamprey, coelacanths and † Tarrasiiformes). Most Palaeozoic fishes had a diphycercal heterocercal tail. [11] a b c Romer, A.S. (1949): The Vertebrate Body. W.B. Saunders, Philadelphia.

Fins can either be paired or unpaired. The pectoral and pelvic fins are paired, whereas the dorsal, anal and caudal fins are unpaired and situated along the midline of the body. For every type of fin, there are a number of fish species in which this particular fin has been lost during evolution (e.g. pelvic fins in † Bobasatrania, caudal fin in ocean sunfish). In some clades, additional unpaired fins were acquired during evolution (e.g. additional dorsal fins, adipose fin). In some † Acanthodii ("spiny sharks"), one or more pairs of "intermediate" or "prepelvic" spines are present between the pectoral and pelvic fins, but these are not associated with fins. a b c d e Romer, Alfred Sherwood; Parsons, Thomas S.

Knowing how to identify a species by its fins and tail shape takes knowledge of anatomy. Other tail shapes are: rounded, truncated, emarginated, lunate, heterocercal, and precaudal vertebrae. Here’s how to identify species by their fins and tails:

7. Heterocercal Tail

Instead of creating forward thrust by moving their tail from side to side as many fishes do, the tails of whales, dolphins and manatees move up and down. This design enables the tail to provide lift for these animals when they break the surface to breathe. Having their blowholes — the body openings to the air passage system — high atop their head also facilitates the breathing process as minimal effort is required to gain access to oxygen-rich air once the animal has reached the water’s surface. a b c Sfakiotakis, M; Lane, DM; Davies, JBC (1999).

It can help to identify different types of fish. To do this, look at features like:
