Relationship of some coleoid
cephalopods established by 3' end of the 16S rDNA and cytochrome oxidase Ill gene sequence comparison.
5,34,35) Eumelanin is also the main component of the ink produced by coleoid
cephalopods, that is squids (Teuthida), cuttlefish (Sepiida), and octopuses (Octopoda).
Molecular phylogeny of coleoid
cephalopods (Mollusca: Cephalopoda) inferred from three mitochondrial and six nuclear loci: a comparison of alignment, implied alignment and analysis methods.
Washington, May 22 (ANI): Some marine animals known as coleoid
cephalopods, which includes octopus, squid, and cuttlefish are wizards of camouflage.
cephalopods, which include squids, cuttlefish, and octopods, are prevalent in global marine environments and serve as an important prey resource to a wide range of fishes, marine mammals, birds, and other invertebrates including conspecifics (Lipinski and Jackson, 1989; Hanlon and Messenger, 1996; Blanc and Daguzan, 2000; Staudinger and Juanes, 2010a).
Phylogenetic analyses of cytochrome c oxidase I sequences to determine higher-level relationship within the coleoid
For this study, the team studied camouflage in the marine animals known as coleoid
cephalopods (octopus, squid, and cuttlefish).
Phylogenetic analysis of cytochrome c oxidase I sequences to determine higher-level relationships within the coleoid
The COI gene for phylogenetic analysis of the coleoid
cephalopods exhibited a high degree of nucleotide sequence variability, with one half of the sites varying in at least one taxon; COI amino acid sequences were highly conserved, but were useful in determining basal-level relationships among the Coleoidea (Carlini et al.
Acetylcholine (ACh), which is synthesized from choline (Ch), is believed to hold a central place in signaling mechanisms within the central nervous system (CNS) of cuttlefish (Sepia officinalis) and other coleoid
Analysis of morphology to determine primary sister-taxon relationships within coleoid
He further hypothesized that "competition" (which in his definition consisted of all "negative" biotic interactions, including predation) with these fishes through visually based interactions led to the (convergent) evolution of modern coleoid
cephalopods (Packard, 1972).
