Fish: a vertebrate that lives its entire life in water All fish have several similar characteristics: Fish are cold-blooded vertebrates that live in fresh or salt water (ectotherms) Fish have backbones Fish have gills that take oxygen out of the water and get rid of car...
The bony fishes are divided into two subclasses, the lobe-finned (or fleshy-finned) fish and the ray-finned fish. The latter group includes over 95% of all living fish species. The earliest bony fishes were fleshy-finned; they gave rise to the amphibians (the first terrestrial vertebrates,...
Other fish species are frequently associated with larger aquatic vertebrates, attaching to them for either phoretic or feeding purposes or both. The aim of this review is to provide an overview of some general patterns in these symbiotic or parasitic relationships, comparing them with more '...
such as the codGadus morhua, or the European hakeM. merluccius, and other gadids (found infected byAnisakisspp.) which feed on both benthopelagic and pelagic organisms. Those organisms could also include crustacean invertebrates, which, in turn, are the first intermediate hosts in these species...
This built on the intimate connection, in the most primitive vertebrates, between the feeding apparatus (i.e., the mouth) and the respiratory apparatus (i.e., the gills adjacent to slits on both sides of the anterior part of the alimentary canal). Water-breathing invertebrates lack this ...
The New York Declaration on Animal Consciousness says there is "at least a realistic possibility" that all vertebrates and many invertebrates have conscious experience. Crab landed on the dock at St. John's Harbour on Thursday, May 6, 2021. THE CANADIAN PRESS/Paul Daly ...
One of thesix basic animal groups, fish are aquatic vertebrates that have skin that is covered with scales. They also feature two sets of paired fins, several unpaired fins, and a set of gills. Other basic animal groups includeamphibians,birds,invertebrates,mammals, andreptiles. ...

Actinomycetes are also present in many free-swimming marine vertebrates and invertebrates, as well as in sessile ones (see Fauna below). They are often detected in marine organisms that produce bioactive metabolites. The pufferfish was the sole identified producer of the potent neurotoxin tetrodotoxin...
