A nautilus (from Latin nautilus ' paper nautilus ', from Ancient Greek ναυτίλος nautílos ' little sailor ') [3] is any of the various species within the cephalopod family Nautilidae. This is the sole extant family of the superfamily Nautilaceae and the suborder Nautilina .
A cephalopod / ˈ s ɛ f ə l ə p ɒ d / is any member of the molluscan class Cephalopoda / s ɛ f ə ˈ l ɒ p ə d ə / (Greek plural κεφαλόποδες, kephalópodes; "head-feet") [3] such as a squid, octopus, cuttlefish, or nautilus.
Palcephalopoda is meant to correspond to groups which are closer to living nautilus, while Neocephalopoda is meant to correspond to groups closer to living coleoids. One issue which this scheme is the necessity of establishing a firm ancestry for nautilus, to contextualize which cephalopods are closer to which of the two living end members.
Catching the cephalopods (the same class as octopus, cuttlefish and nautilus) is relatively easy, even from shore, although it can take some patience. Perhaps more important is the question: what ...
Edible molluscs are used to prepare many different dishes, such as Oysters Rockefeller (pictured). This is a partial list of edible molluscs.Molluscs are a large phylum of invertebrate animals, many of which have shells.
There are some food items that are simply hard to eat. Some foods, like ice cream cones, don't require any special equipment to get to the good stuff, but you'd be hard-pressed to finish a whole ...
The chambered nautilus (Nautilus pompilius), also called the pearly nautilus, is the best-known species of nautilus. The shell, when cut away, reveals a lining of lustrous nacre and displays a nearly perfect equiangular spiral, although it is not a golden spiral. The shell exhibits countershading, being light on the bottom and dark on top. This ...
Nautilus have unique sensory organs, which differ from related genera in several ways. Unlike other cephalopods, the eyes of Nautilus species lack ocular muscles and instead move via a stalk, which contains both muscle and connective tissue. Additionally, Nautilus eyes lack any lens or cornea and only have an aperture to allow for light.
