Cephalopoda is the most morphologically and behaviorally complex class in phylum Mollusca. Cephalopoda means head foot and this group has the most complex brain of any invertebrate. Cephalopods are characterized by a completely merged head and foot, with a ring of arms and/or tentacles surrounding the head. The arms, tentacles, and funnel are. Three main clades are typically identified within the Cephalopoda (cladogram B, left): the Ammonoidea (an extinct and shelled clade), Nautiloidea (with only one living shelled genus, Nautilus) and Coleoidea (squids, cuttlefish, octopuses, the Ram's Horn Squid, the paper nautilus, and an extinct clade, the belemnites). The ammonoid lineage. Cephalopod - Cephalopod - Form and function: Cephalopods vary from elongate, streamlined oceanic organisms to saccular, slow-moving bottom and drifting forms. Their body plan is indicative in many ways of the habitat in which they dwell and their mode of life. The viscera of a generalized cephalopod are covered by a dome-shaped or elongated sheath of muscle, the mantle, which is connected with. Cephalopoda is an ancient and successful group, including some of the dominant large marine predators during various periods in geological history (Young et al. 1996). Cephalopods appeared 500 million years ago during the late Cambrian and were dominant and diverse during the Paleozoic and Mesozoic eras

Cephalopods. The cephalopods are a small group of highly advanced and organized animals, exclusively marine. Octopus, squid, cuttlefish and nautilus are members of this group. The extinct forms surpass in number those that have remained alive, and as a species, has reached a great diversity at the end of the Paleozoic and Mesozoic Aki először járja be Olaszországot, abban nemcsak a flórenci paloták, a Colosseum, a nápolyi öböl a háttérben füstölgő Vezuvval, a halott Pompeji és a paestumi templomromok hagynak eltörülhetetlen emléket, hanem lenyűgöző hatással van rá a nagyobb városok halpiacának a látványa is, amint az napról napra a bámuló szem elé tárul Génuában, Livornóban, Nápolyban. Cephalopods can change color faster than a chameleon. These changeable mollusks are active swimmers who can quickly change color to blend in with their surroundings. The name cephalopod means head-foot because these animals have tentacles (feet) attached to their head..

Cephalopoda This site is a broad overview of Cephalopoda written by students from University College Cork, Ireland . Evolution It is believed that the earliest cephalopods derived from a mollusc similar to the modern limpet during the late Cambrian. The first step this ancestral form took towards an increasingly mobile life was the elongation. Two new species of the genus Octopus, discovered in the shallow water of the southern Caribbean, are described. Both octopuses are common in the local artisanal fishery. Octopus tayrona n. sp. is characterized by having 112 to 135 suckers on hectocotylized arm, a small ligula (LLi 0.42-1.62) with a calamus about one third to one half the length of the ligula, and ctenidia with 9-12. Source: Cephalopoda Glossary. Picture: Mark Norman. Like other molluscs cephalopods have got a radula or rasp tongue to rasp their food to pieces. In addition to that they also have a beak made out of horn, like that of a parrot, with which the prey is cut to pieces before being swallowed. The beak can also serve to crack open the prey's armour. Bruno Baur, in Sperm Competition and Sexual Selection, 1998. A Mating systems. All cephalopods are gonochoric (Heller 1993), and cross-fertilization is the rule.In general, a sex ratio of 1:1 is assumed in cephalopods, as has been observed in Loligo pealei (Summers 1971).However, deviations from an even sex ratio have been recorded in several species (review by Mangold-Wirz 1963) Los cefalópodos (Cephalopoda, del griegu κεφαλή (kephalé), cabeza y ποδός (podós), pie → pies na cabeza) son una clase d'invertebraos marinos dientro del filu de los moluscos.

Over 700 species of cephalopods live in the Earth's waters, occupying almost every marine zone, from the benthic deep to the open ocean to tidal waters. The greatly varied forms and charismatic behaviors of these animals have long fascinated humans. Cephalopods are short-lived, highly mobile predators with sophisticated brains that are the largest among the invertebrates Besides multiple arms, these class Cephalopoda examples have three hearts and blue blood. They can also fend off predators by squirting ink. You can find octopuses all over the world's oceans. Squid. Squids are also popular cephalopods. Like octopuses, these creatures have eight arms that are relatively short compared to their large heads Few groups of animals are as dazzling and diverse as the cephalopods, a group of around 800 living marine species that includes squid, octopuses, cuttlefish, and nautiluses.
