Excretory opening of the digestive tract in fishes.

ventral-fin basket

Vernacular nerm used to describe the post-spawning behaviour of cupping or clamping of the ventral fins in order to transport fertilised eggs. Exhibited by females of some Corydoras species, for example.

ventral-fin

Either of the pair of fins, also known as pelvic fins, attached to the pelvic girdle in fishes that help control the direction of movement. Correspond to the hind legs in higher vertebrates and vary in position depending on taxon. Sometimes absent entirely.

dorsoventrally

In a dorsoventral direction or sense.

parahypural

Most ventrally-located of the hypural elements.

basibranchial

Of, being, or relating to a median ventral cartilage or bony element located at the ventral point of a branchial arch, behind the tongue if the latter is present.

adipose crest

Fatty ridge of flesh extending along the dorsal or ventral surface of the caudal peduncle in certain fishes, e.g., some Schistura spp.

Used in 7 profiles

anal-fin

A median, unpaired, ventral fin located between the anus and caudal fin, usually in the posterior portion of the body. Used to maintain equilibrium and stability.

Used in 764 profiles

axillary process

A modified, often elongate, scale or group of scales located at the base of the pectoral or ventral fins in some fishes.

basibranchial teeth

Teeth on the median ventral plate (base of the tongue) overlying the basibranchial bones between the gill arches in some fishes.

body depth

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.
