Life of the Osteichthyes Breathing: nearly all fishes inhale by sketching drinking water over 5 sets of gills, located in chambers, protected by a defensive bony flap called the operculum. Three pairs of tooth-bearing dermal bones lining the jaws (dentary, premaxillary and maxillary). Can inhale and exhale through lungs or vascularized swim bladders or through their epidermis, intestines or tummy. Skin fin rays made up by lepidotrichiae (improved, tile-shaped weighing scales) Some bony seafood are usually hermaphrodites. Info for Osteichthyes (bony fishes) Features of the cIade: Endochondral ('spongy') bone fragments in the endoskeleton Ectothermic (chilly blooded) = their entire body temperature is reliant on that of the drinking water. The group has bilateral symmetry The phylum of Osteichthyes is certainly Chordata (either vértebrates or one óf many closely associated invertebrates) Domains Eukaryota -Empire Animalia -Phylum Chordata Amphibians are usually the nearly all closely related team The Phylum Chordata (vertebrates) times 530.000.000 years back and people (from 200.000 years ago) originate from it.

More than 29,000 species Have got bony (ossified), as compared to cartilaginous, skeIeton =endoskeleton with á difficult matrix of calcium supplement phosphate.

Osteichthyes (bony fishes) Osteichthyes will be a taxonomic team of fish which means bony seafood the title was coined very long before the advent of phylogenetic systematics. Bony and cartilaginous fishes are usually clades of the different types of vertebrates: 0steichthyes (bony fishes) - CIades: Ray Finned Fishes (Actinopterygii) and Lobe-Fins (Sarcopterygii and Dipnoi) Gnathostomes (jawed vertebrates) Clade: Chondrichthyes (cartilaginous fishes).Notice: Both bony ánd cartilaginous fishes discuss the 4 derived features of their common phylum: Chordata, which are: the notochord (dorsal stiffening rod) a empty dorsal nerve wire pharyngeal gills a post anal end that consists of the notochord and nerve wire. Bony and cartilaginous fishes Vertebrates are classified based on traditional interpretations of gross physiological and physical traits.
