The beak is part of the shell of a bivalve mollusk, i.e. part of the shell of a saltwater or freshwater clam. The beak is the basal projection of the oldest part of the valve of the adult animal. The beak usually, but not always, coincides with the umbo, the highest and most prominent point on the valve. Because by definition, all bivalves have ...
The beak of a giant squid. All extant cephalopods have a two-part beak, or rostrum, situated in the buccal mass and surrounded by the muscular head appendages. The dorsal (upper) mandible fits into the ventral (lower) mandible and together they function in a scissor-like fashion. [1] [2] The beak may also be referred to as the mandibles or jaws ...
The two-part beak of the giant squid, Architeuthis sp. All living cephalopods have a two-part beak; [11]: 7 most have a radula, although it is reduced in most octopus and absent altogether in Spirula. [11]: 7 [97]: 110 They feed by capturing prey with their tentacles, drawing it into their mouth and taking bites from it. [24]
A common gene between cuttlefish and almost all other cephalopods allows them to produce venom, excreting it through their beak to help kill their prey. [34] Additionally, the muscles of the flamboyant cuttlefish ( Metasepia pfefferi ) contain a highly toxic, unidentified compound [ 2 ] as lethal as the venom of fellow cephalopod, the blue ...
Mollusca is a phylum of protostomic invertebrate animals, whose members are known as molluscs or mollusks [a] (/ ˈ m ɒ l ə s k s /). Around 76,000 extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda . [ 5 ]
[58] [59] [60] The Gorgon of Greek mythology may have been inspired by the octopus or squid, the severed head of Medusa representing the animal, the beak as the protruding tongue and fangs, and its tentacles as the snakes. [61] The six-headed sea monster of the Odyssey, Scylla, may have had a similar origin.
The alligator snapping turtle is the largest freshwater turtle in the world and can live up to 70 years. It is black or dark brown, and their shell is thick with pronounced spikes. Its beak-like ...
The beaks of Argonauta species are distinctive, being characterised by a very small rostrum and a fold that runs to the lower edge or near the free corner. The rostrum is "pinched in" at the sides, making it much narrower than in other octopuses, with the exception of the closely allied monotypic genera Ocythoe and Vitreledonella .
