The name "anglerfish" derives from the species' characteristic method of predation. Anglerfish typically have at least one long filament sprouting from the middle of their heads, termed the illicium. The illicium is the detached and modified first three spines of the anterior dorsal fin. In most anglerfish species, the longest filament is the ...
Ceratioidei, the deep-sea anglerfishes or pelagic anglerfishes, is a suborder of marine ray-finned fishes, one of four suborders in the order Lophiiformes, the anglerfishes.
It preserves fossils dating back to the middle to upper Miocene epoch of the Neogene period, most of which were deposited in a deepwater environment. [2] Owing to its depositional environment, it is one of the very few geologic formations to preserve articulated specimens of fossilized deep-sea anglerfish .
Prehistoric fish are early fish that are known only from fossil records. They are the earliest known vertebrates, and include the first and extinct fish that lived through the Cambrian to the Quaternary. The study of prehistoric fish is called paleoichthyology.
Monte Bolca is an Early Eocene-aged geologic site located near Verona, Italy.A Konservat-Lagerstätte, it contains an extremely well-preserved and diverse marine biota, including the most diverse fish fauna of any Cenozoic fossil site, as well as many of the earliest fossil occurrences of modern marine fish groups.
The fanfin family, Caulophrynidae, takes its name from the genus Caulophryne.This name is a combination of caulis, which mean" stem", an allusion to the stem-like base of the illicium, with phryne, meaning "toad", a suffix commonly used in the names of anglerfish genera.
Acanthostega (meaning "spiny roof") is an extinct genus of stem-tetrapod, among the first vertebrate animals to have recognizable limbs.It appeared in the late Devonian period (Famennian age) about 365 million years ago, and was anatomically intermediate between lobe-finned fishes and those that were fully capable of coming onto land.
The goosefish family, Lophiidae, was first proposed as a genus in 1810 by the French polymath and naturalist Constantine Samuel Rafinesque. [2] The Lophiidae is the only family in the monotypic suborder Lophioidei, this is one of 5 suborders of the Lophiiformes. [3]
