See more at fin Examples of caudal fincaudal fin All infections commenced with a single gravid worm attached to the central region of the caudalfin. Migration, and distance from the caudalfin, increased with parasite age. Parasites placed in the central region of the caudalfin moved anteriorly on the body. Synchronized ventral fins have been added to the production model, whereas pectoral fins and a caudalfin were already present on the prototype. One can observe the wide variety of caudalfin features and conditions. The selection of templates with different caudalfin angles improves the rotation-invariance property of the method. The caudalfin is forked, with slightly unequal lobes. Note that at a short distance anterior to the caudalfin, where lateral oscillation amplitudes begin to rapidly increase, the body depth is greatly reduced. These donor fish had 50% of their caudalfin cut off vertically so as to differentiate them from fish in the experimental groups. Most pre-first birth worms born on the caudalfin, remained on this fin, but did occasionally move on to the peduncle. The second group, which was marked by cutting off the upper lobe of the caudalfin, contained 15 fish that were administered heat-inactivated immune sera (with heat-inactivated complement). Movements of any horizontal section of caudalfin, with yaw angle fluctuating in phase with its velocity of lateral translation, are studied for different positions of the yawing axis. For the carangiform locomotion, the body's undulations are entirely confined to the last third of the body, and thrust is produced by means of a rather stiff caudalfin. Through careful positioning of parasite and fish (monitored using a stereo-microscope), it was possible to ensure that the parasite always attached to the central region of the caudalfin. The fishes with which we are here concerned have the depth of their caudalfin practically as large as (or larger than) that of the dorsal fin and body combined.
