Ichthyological terms, not general ones.
The vertical distance between the dorsal and ventral margins of the body measured at the base of the pectoral fin where it joins the body. In most icthyological works the greatest dimension, normally anterior to the dorsal fin, is taken but in some cases body depth is measured at the origin of pectoral, pelvic and first anal. Fins or fin bases are not included in the measurement, however.

Refers to the collar bone in human anatomy. Present in the pectoral girdle of some fishes as a paired, dermal bone ventral to or fused with the cleithrum.
Used in 1 profile
Variably-sized (depending on species), usually dark marking present in the cleithral area dorsal to the pectoral fin insertion. Normally visible externally in llive specimens.
Used in 17 profiles
Major bone of the pectoral girdle. Extends upward from the pectoral fin base and forms the rear margin of the branchial cavity. Articulates with the supracleithrum dorsally, the scapula and coracoid ventrally. Also known as proscapulum.

Phylum of aquatic organisms that includes the corals, jellyfishes, sea anemones, hydrae, etc., and characterised by possession of specialised venomous cells known as cnidocytes. Formerly included in the now-defunct phylum Coelenterata.
Paired endochondral bone located at the base of the pectoral fin upon which rest the pterygials or actinosts. Attaches to the cleithrum anteriorly.
Used in 18 profiles
Bony process extending posteriorly from the pectoral girdle, above the base of the pectoral fin. Present only in certain fishes.
Used in 8 profiles
A marking on the body in the area analogous to the humerus, or shoulder. In fishes it's normally located above the pectoral-fin and behind the opercle. There may be more than a single such spot in some species.
Used in 42 profiles
The pectoral girdle in most fishes.
Of or relating to the neck or throat. Sometimes used in reference to a fish possessing pelvic fins located in front of the pectoral fins.
Bony process or plate at the base of the first ( unbranched ) and second ( first branched ) ray of the pectoral-fin in most male specimens of the family Cobitidae. It is also known as 'Canestrini's scale'.
Used in 24 profiles
Paired bone situated in the pectoral girdle, below the cleithrum.
The pectoral and pelvic/ventral fins, both of which occur in pairs and are analogous to the fore and hind limbs in higher animals.
Used in 58 profiles
Bony or cartilaginous structure supporting the pelvic fins. Sometimes fused with the pectoral girdle.
Used in 9 profiles
The inability of two or more groups of organisms to interbreed due to the existence of geographical, behavioral, physiological, or genetic barriers. These can be further separated into those being active pre- or post-copulation.
Form of niche differentiation by which two species partition (divide) a resource based on behavioral or morphological variation in order to ensure their mutual survival by reducing competition.
Used in 11 profiles
Paired bone attached to the pterygials, actinosts or radials of the pectoral fin. Articulates ventrally with the coracoid and anteriorly with the cleithrum.
Any member of the yellow-green algae genus Symbiodinium, comprising unicellular, flagellate protozoa that exist within the cells of other protozoa and some invertebrates, especially corals. They thus form an endosymbiosis in which they can provide up to 90% of the host's energy requirements.
