WHALE FLUKES
A whale's tail is called its flukes. The flukes are used in swimming.
High fluke: The fluke is also triangular and very thick. Flukes are lifted very high out of the water before a whale begins a deep dive.

Tapeworms and flukes can infect aquatic turtles, but are rare in tortoises. These parasites need to go through an intermediate host and are not much of a problem in most well-cared-for captive turtles.
A: The tail or fluke of a gray whale consists of two large flukes with a notch between them and is positioned horizontally on the whale.
TREMATODES, or flukes (as they are called from their fish-like shape), one of the three classes that compose the phylum Platyelmia.
At perhaps 4 to 5 miles east of the Isles of Shoals one sharp eyed observer saw, very briefly, the flukes of a Humpback Whale as it started a terminal dive, never to be seen again.
giant liver flukes, rumen flukes (Paramphistomum spp.), and tapeworms (hydatid worm (Echinococcus granulosus) and Taenia spp.), nematodes (e.g.
The fin has two flukes, one on each side. They are both symmetrical and are flat and rigid and lie horizontally. The flukes move up and down while they swim. Flukes are usually 18 feet long.
The fluke, which can be 5.5 m wide, is serrated and pointed at the tips. One of the humpback's more spectacular behaviors is the breach.
Blue whales have a long, streamlined body that tapers to its tail flukes. The head of a blue whale is wide and flat and contains 50-60 ventral pleats that allow the mouth of the whale to expand and hold more water.
The undersides of the flippers and flukes are almost all white. The baleen plates are about three feet long, black with black or olive-black bristles; there are 300-320 plates on each side of the upper jaw.
A small, toothed whale; upperparts, top of pectoral fins, and flukes blackish; underparts and upper lip, white; dorsal fin small, situated posterior to the mid-point on back, the tip pointing backwards; pectoral fin short and "spear-shaped"; ...
Colouration: mostly black, belly sometimes white, flippers and underside of flukes nearly all white, baleen plates black with black or olive-black bristle.
*** Although humpback whales have a variety of individually unique markings and coloration patterns, the underneath surface of the flukes provides the best opportunity for identifying individuals.
One thinks of the light line with the brownish colored codfish or the black side-line, that itself with the cod, behind the gill-covers, over which entire bodies and tail-stalk stretch and finish before the tail fluke, incipient.
The tail flukes are horizontal in all the cetaceans (unlike fish tails which are vertical) and the movement of this powerful tail propels them through the water.
They are small cetaceans, with robust bodies and small heads, flukes, and flippers. Reproductively, they differ from many cetaceans by breeding annually, calving in June or July and mating soon thereafter.
Whales sometimes lift their tails (each half is called a fluke) high above the water and slap them down on the surface making a tremendous splash that can be heard far away. This lets other whales know its position.
The body is robust and narrows rapidly in front of the huge tail flukes. Its colour is black (occasionally brown) and sometimes mottled, with white patches on the chin and belly. The head is large comprising 30% of the length of the body.
Humpbacks are powerful swimmers, and they use their massive tail fin, called a fluke, to propel themselves through the water and sometimes completely out of it.
The Dugong is a large, grey brown bulbous animal with a flattened fluked tail, like that of a whale, no dorsal fin, paddle like flippers and distinctive head shape.
Black bears have been reported to host more than 30 external and internal parasites, including coccidian protozoans, flukes, tapeworms, intestinal roundworms, lungworms, filarial worms, lice, fleas, ticks, and mites.
The dolphin's sleek, fusiform body, together with its flippers, flukes, and dorsal fin, adapt this animal for ocean life. A dolphin's forelimbs are pectoral flippers.
Rather than pairing up everything in the aviary and hoping you will fluke a good one. Although, this seems to be a current trend with many breeders adding more and more breeding cages.
I'm tremendously jealous though I probably shouldn't be; I guess I'm probably one of the few birders to totally fluke a sunbittern sighting when they had absolutely zero expectation of one - a bird flew past our boat as we were moored up ...
Northern bottlenose whales have broad flukes without notches. The trailing edge of the fluke is concave. They are capable of dives averaging 14 to 70 minutes and can stay underwater as long as 2 hours.
The up and down motion of the dolphin's tail fluke helps bring its head up to the surface so it can breathe through the blowhole on top of its head.
The outer surface of the dolphin's skin is replaced about every two to four hours.
Cetaceans have long torpedo-shaped bodies and tails that end in flukes. They have an air or blow hole on the top of their head. Like most mammals, they give birth to live young and feed them milk. There are about 80 species in this order.

The undersides of the flippers and flukes are also white. Some fin whales have a pale grey chevron on each side behind the head and there may be a dark stripe running up and back from the eye, ...
Their large bodies are streamlined (hydrodynamic), like a submarine, for moving through the water. Whales have flukes or a tail used for swimming. The flukes are moved in an up-and-down motion to accelerate.
Whales have streamlike bodies with highly compressed neck vertebrae, dorsal fins, and a tail with two finlike flukes arranged horizontally.
Parasites of Herring gulls include the fluke Microphallus piriformes.

During mating season, male whales will physically battle for access to females, often striking each other with their tail flukes, flippers, and chins, and even drawing blood in spectacular displays of aggression.
This is the field Zimmer unblinkingly explores, replete with scenes of dissections that expose the worms, flukes, and single-celled organisms that invade a host. Gross! ...
Sometimes there is a white or gray patch on tail stock and flukes. There is no dorsal fin. It has 300 large baleen plates on each side of the mouth. These plates are about 3m - 4.5m in length.
Most of the body is pale with brown speckles in colour, though the neck, head and edges of the flippers and fluke are nearly black. Older animals are usually more brightly coloured than younger animals.
Their bodies resemble the streamlined form of a fish, while the forelimbs or flippers are paddle-shaped. The tail fins, or flukes, enable whales to propel themselves through the water.
This involves raising their broad tail flukes out of the water and then crashing them down. They will also use their flippers to slap the water surface. The behaviours may be useful in communication between individuals.
They include many important commercially fished species, including not only the various fish called flounders, but also the European plaice, the halibuts, the lemon sole, the common dab, the Pacific Dover sole, and the flukes.
Their tiny hind limbs are vestigial; they do not attach to the backbone and are hidden within the body. The tail has horizontal flukes. Whales are practically hairless and are insulated by a thick layer of blubber.
Flukers (and other companies) produce a bubbling bowl that will put more moisture into the cage. If your humidity is not quite up to 70%, mist the enclosure, especially the leaves of the plants inside, daily.
The flippers and underside in some of the tail-flukes are usually mostly white. Humpback whales are able to mke spectacular leaps clear of water and also sometimes swim on their sides with one long flipper held out of the water.
Pointed pectoral fins aid in steering, broad horizontal tail flukes move up and down, propelling them through the water, and a single, curved dorsal fin on their back provides them stability as they move through the water.
A baleen (toothless) whale, it has a long rigid snout and a double blow-hole. The gray whale does not have a dorsal fin but does have a low hump on its back and a series of small knobs or "knuckles" running down to the flukes.
