Coelacanths (/ ˈ s iː l ə k æ n θ / ⓘ SEE-lə-kanth) (order Coelacanthiformes) are an ancient group of lobe-finned fish (Sarcopterygii) in the class Actinistia. [2] [3] As sarcopterygians, they are more closely related to lungfish and tetrapods (which includes amphibians, reptiles, birds and mammals) than to ray-finned fish.
Most adult female ceratioid anglerfish have a luminescent organ called the esca at the tip of a modified dorsal ray (the illicium or fishing rod; derived from Latin ēsca, "bait"). The organ has been hypothesized to serve the purpose of luring prey in dark, deep-sea environments, but also serves to call males' attention to the females to ...
Rather than typical dorsal fins, the front-most of the three fins is called the illicium or "rod" and is topped with the esca or "lure". The illicium often has striped markings, while the esca takes a different form in each species.
In anglerfish, the anterior of the dorsal fin is modified into an illicium and esca, a biological equivalent to a fishing rod and lure; The bones that support the dorsal fin are called pterygiophores. There are two to three of them: "proximal" (axonosts), "middle" (baseosts), and "distal". In rock-hard, spinous fins the distal pterygiophores ...
Freshwater anglers typically use lightweight, faster-action rods and for panfishing or finesse fishing for popular mid-sized game fishes such as black bass or trout, while sturdier, heavier rods are used for larger, stronger and feistier fish. When casting light rods, sidearm casting techniques are typically used.
The cobia (Rachycentron canadum) (/ ˈ k oʊ b i ə /, KOH-bee-ə) is a species of marine carangiform ray-finned fish, the only extant representative of the genus Rachycentron and the family Rachycentridae.
Teleostei (/ ˌ t ɛ l i ˈ ɒ s t i aɪ /; Greek teleios "complete" + osteon "bone"), members of which are known as teleosts (/ ˈ t ɛ l i ɒ s t s, ˈ t iː l i-/), [4] is, by far, the largest group of ray-finned fishes (class Actinopterygii), [a] with 96% of all extant species of fish.
