The fish have been clipped on the adipose fin between the tail and dorsal fin to enable anglers to identify their catch as a stocked fish. Rare fish added to toxic bloom lake The morphologic identification of the adults of these fish species relies on the dorsal fin and adipose fin length;...
FINS (Anatomy)GENOTYPESGoldfish (Carassius auratus auratus) are important ornamental fish that have experienced extreme anthropogenic selection and exhibit diverse phenotypes. Loss of the dorsal fin is a key characteristic that distinguishes the Egggoldfish from the Wen-goldfish. Howe...
homocercal fin- symmetrical tail fin extending beyond the end of the vertebral column as in most bony fishes fish- any of various mostly cold-blooded aquatic vertebrates usually having scales and breathing through gills; "the shark is a large fish"; "in the living room there was a tank of...
In more advanced agnathans, a long-based preanal finfold is generally absent. Instead, many taxa possess a shorter-based and more posteriorly positioned anal fin. An anal fin is present in all anaspids that are sufficiently known from their postcranial anatomy. Furthermore, a preanal fin an...

Basic Anatomy The slender build accompanied by a dark grey-brown tone and a white underbelly is characteristic of the Finbacks. Instead of teeth, Finback whales possess baleen plates made of keratin, in a set of 350-400 depending upon the age. They also have a series of 85-100 ventral ...
We also note, however, that a second major difference affecting the differences in maximum [O2]delivery between the shortfin mako shark and tunas appears to be gill anatomy. As described by Wegner et al. (2012), the former have greater interlamellar spacing, fewer secondary lamella and a ...
The fin-to-limb transformation is a paradigmatic example of morphological evolution1. The distal skeletal patterns of vertebrate limbs and fins have changed multiple times during evolution (Fig. 1a), and their homologous relationships have been controversial2–7. According to comparative anatomy, ...
