Major Events in Early Vertebrate Evolution
There is some regionalisation in the endoskeletal morphology, with a boundary
between the first hypural (h1) and parhypural (p). This is the location at which the
caudal lepidotrichia begin forming (Figure 15.4a). Dr=distal caudal radials; ...

The Osteology and Relationships of the Uranoscopoid Fishes
The lower part is subdivided and the anterior part of it is composed of a wide
haemal bone that is attached to the hypural centrum by a smooth suture. From its
upper posterior angle a conspicuous process projects upward, outward, and ...

Cornelis Groot, L. Margolis, 1991
The whole structure is referred to as the urostyle or more loosely as the hypural
plate (although only in sticklebacks, family Gastero- steidae, is a single hypural
plate present). Because the hypural region is under stress when the fish swims,
the ...

On some specimens, several stellate chromatophores are present at the base of
the tail — located at the juncture of the two hypural elements. This pigment is the
beginning of a future caudal spot. A few small chromatophores are scattered ...

Locomotion: Volume 7: Locomotion
Their split bases are widened and flattened to grasp the hind edge of the hypural
bones. The major rays (whose number is largely fixed and characteristic for each
species) bifurcate dorsoventrally several times as they approach the trailing fin ...

Recreational Fisheries: Management, Theory, and Application
In comprehensive work the standard, fork, and total lengths are measured to the
nearest millimeter. Standard length is the distance from the end of the snout to
the hypural plate (the modified last vertebrae). Only "modern" fishes have a
hypural ...

The hypural plate forms the surface onto which the caudal fin rays attach
proximally. Head length is the straight-line distance between the tip of the snout
and the opercular flap (Figs. B and C). Fork length is used in fishes such as
carangids ...
