Ichthyological terms, not general ones.
Any of the bony or cartilaginous structures forming the framework of the mouth, usually vertically opposed, often bearing teeth and primarily used for acquisition of food. Often modified in fishes to form complex protrusible or sucking arrangements, for example.

Tooth-like projection in the middle of the upper jaw in certain loach genera which may fit into a notch in the lower jaw. Also referred to as dentiform process.
Used in 16 profiles
Mouth oriented and opening primarily forward but also somewhat ventrally, i.e., the upper jaw and snout clearly extend beyond the lower jaw
Used in 8 profiles
A compound bone formed by the fusion of the dermal angular and the cartilaginous articular and comprising the posterior part of the lower jaw.
Used in 5 profiles
A slender, whiskerlike, external process on the jaw or other part of the head of certain fishes used for touch and taste. Also used to refer to European members of the cyprinid genus Barbus.
Used in 319 profiles
A membrane, paired, bone in the upper jaw, located ventrally on the skull. Some fishes, such as serrasalmids, possess small tooth-like projections known as ectopterygoid teeth on this bone.
Used in 4 profiles
The width of the space between the jaws when open to their maximum extent.

Of or relating to the jaw.
Segment of the hyoid arch connecting the lower jaw to the skull.
Used in 16 profiles
The lower jaw bone of a vertebrate organism.
Used in 2 profiles
Either of two fused bones forming the upper jaw, displaced inwardly by the premaxilla in some fishes. May bear teeth.
Used in 38 profiles
Of or relating to a maxilla; a jawbone.
Used in 50 profiles
Distance between the tip of the upper jaw to the anus.
Used in 7 profiles
Distance between the tip of the upper jaw and inseryion/origin of first dorsal fin..
Used in 19 profiles
Either of the paired, dermal bones located in front of and between the maxillary bones in the upper jaw. Often bear teeth.
Used in 49 profiles
Capable of being extended or thrust forwards. Often used in reference to the jaws of certain fishes.
Used in 13 profiles
Barbel located between the upper and lower jaws, i.e., at or close to the corner of the mouth.
Used in 2 profiles
The projecting mouthparts, jaws, or part of the head anterior to the eyes.
Used in 285 profiles
Distance between the tip of the upper jaw and anterior margin of the orbit.
Used in 30 profiles
Measurement taken from the tip of the snout to the midlateral, posterior edge of the hypural plate or posterior edge of the last vertebra, thus excluding the caudal fin. May also exclude the length of the lower jaw should it project beyond the snout. It is the standard scientific measurement used for most fish species because the caudal fin easily becomes damaged in preserved specimens. Abbreviated to SL.
