4 de nov. de 2021 · Whale tails, called flukes, have unique characteristics that can be used to identify individual whales, helping researchers to study and monitor individuals and populations over time. © Rhys Watkin. Humpback whale flukes, like all cetacean flukes, have two lobes (or flukes): a left lobe (or fluke) and a right lobe (or fluke).
24 de abr. de 2017 · •••. Updated April 24, 2017. By Ethan Shaw. A whale’s flukes are distinctive and important parts of its anatomy--and some of the most commonly seen by observers in a boat or the shore. The Flukes. •••. A whale’s flukes are its tail fins, which are composed of flesh and not anchored by skeletal anatomy.

Humpback whale showing flukes. The tail fin, formally known as the fluke, is a powerful fin that works primarily to propel the animal forward. Unlike fish, which have tails that move from side to side (vertically), the whale’s fluke moves up and down, or horizontally, in powerful strokes.
Right whale flukes have 67% of the area of the humpback, ... The smaller morphology of PCFG may also be related to foraging tactics employed on different prey and habitat types.

Humpback, southern right and blue whales make their way along Australia's coastlines at different times of the year and can be spotted from vantage points in places like the coastal town of Albany in southern WA. Kirsty Alexander, an Albany-based marine biologist who coordinates a citizen science project studying cetaceans or marine mammals, is an ...
Southern right whales can be found on Australia's east, west and southern coastlines and migrate between summer feeding grounds in the Southern Ocean. Mrs Alexander said this species was often spotted close to coastal communities such as Albany because they were seeking out the shallow, protected bays along the coast to breed. "Because they come in...
During the winter months, humpback whales migrate northwards along Australia's east and west coasts to their calving grounds and from September they head back down to feed near Antarctica. "They are most easily identified if you actually see them surface and dive again," Mrs Alexander said. "These flippers are a fairly significant feature and they ...
The blue whale — the largest animal that ever lived — can be spotted along Australia's southern coastline from November to June. Mrs Alexander said spotting a blue whale was a very special occasion. "Those guys tend to have a very tall, bushy blow or spray, which gets our local whale watch operators pretty excited if they see that," she said. "When...
Mrs Alexander said anyone could contribute to whale research once they knew what to look for. "If you are a researcher, whales are pretty mobile and for these guys it is nothing to travel 6,000 kilometres one way when migrating," she said. "So it is very difficult to be able to find them and to be able to be with them for long enough to study [the ...
17 de mar. de 2024 · During the land-to-sea transition of cetaceans (whales, dolphins, and porpoises), the hindlimbs were lost and replaced by an elaborate tail fluke that evolved 32 Ma. All modern cetaceans utilize flukes for lift-based propulsion, and nothing is known of this organ's molecular origins during embryonic development.
22 de abr. de 2019 · The most obvious adaptations in extant whales include a streamlined body, loss of hindlimbs, and the development of a large muscular tail with a fluke that provides forward propulsion [10]. In the few extant whales that retain hindlimbs, only the proximal bones ossify, and none protrude beyond the body wall.
