Fin Whale Facts | Fin Whale Diet & Habitat
The fin whales primarily feed on squid, copepods, krill, and crustaceans. The whales inhabiting in the North Pacific, are known to prey on Euphasusia pacifica, Nyctiphanes simplex, T. spinifera, squid, herring, walleye Pollock, sand lance, capelin, E. superba, and larger copepods. Name: Fin Whale (Balaenoptera physalus) a.k.a. Finback Whale, Razorback Whale, Common Rorqual. Length: 27 metres. Weight: 74 tonnes. Location: Worldwide, except under polar ice caps. Conservation status: Endangered. Diet: Small fish, squid, crustaceans (copepods, krill) Appearance: Grey, lighter underside. What do Fin Whales eat?
Fin whales are the fastest amongst the cetaceans and have been seen to breach completely out of the water. It is gray on the upper surface and white on the underside. Patterns on its jaw are asymmetrical: white on the right and dark on the left side, with large numbers of grooves extending along the throat to its naval.
Its prominent dorsal fin has a strong curve. Males and females are very similar in appearance, with females slightly longer than males. Their baleen plates are gray to bluish in color, with white fringes. They have two blowholes, with a single, longitudinal ridge extending from the tip of their snout to where their blowholes begin.
This species is distributed throughout the globe, though it is rarely seen in tropical or icy polar seas. It has two subspecies: the northern fin whale, which inhabits the North Atlantic; and the southern fin whale, which lives in the Southern Ocean. It is the only rorqual found what is capital gain tax on sale of property in the Mediterranean.
They inhabit the polar and temperate zones of major and open seas as well as, less commonly, the tropical oceans. They more commonly live in shelf and coastal waters, never in water that is less than a depth of meters. Fin whales are one of the most sociable of whale species, often congregating in family groups of 6 to 10 members. Sometimes they gather in groups of almost individuals during migration periods or near feeding grounds. This species is highly migratory: they usually live in colder feeding water during spring and early summer, and in autumn and winter they go back to warmer waters to breed.
A fin whale is a filter feeder and hunts by swimming with its mouth open towards its prey, taking in large amounts of water as well as food. Fin whales communicate with loud low-pitched sounds. The purpose of these noises is unknown, but they may play a part in helping whales to locate each other or attract a mate.
Fin whales mainly eat plankton-sized animals including fish, crustaceans, and squid. Fin whales are regarded as monogamous, often being seen during the mating season in pairs. Mating takes place in the northern hemisphere between November and January, and the southern hemisphere between June to September.
After an A calf is precocial at birth, and is able to swim as soon as it is born. A mother nurses her baby for 6 to 8 months.
The calf is about 14 meters long when it how to play beatles yesterday on guitar weaned, whereupon it travels to a polar feeding area with its mother, and learns there to feed independently of its mother. Males are sexually mature at 6 - 10 years old. Females give birth to a calf every two years once they reach sexual maturity between 3 to 12 years old. Fin whales, like other large whales, are threatened by changes to the environment, including habitat loss, climate change and toxins.
At present, fin whales are threatened by manmade injuries, the most serious being collisions with boats. They are also threatened by commercial whaling. The majority of whale meat is bought on the Japanese market. There are very rough estimates for specific regions: North Atlantic - 53, whales; Mediterranean Sea - fewer than 10, whales; North Pacific — 17, whales; Southern Hemisphere - 38, whales. Currently the Fin whale is classified as Endangered EN. Fin whales have a place at the top in the food chain and an important role as regards the marine environment's overall health, consuming vast amounts of plankton as well as other prey items.

Fun Facts for Kids Fin whales can expand their mouths and their throats while feeding due to the or so pleats that go from the end of their bodies right to their mouths.
The pleats enable the mouth cavity during feeding to engulf water, Fin whales being filter feeders, with to baleen plates that they use to catch very small up to medium-sized life that is suspended in the sea.
Fin whales can dive as deep as meters and stay submerged for around 15 minutes. A fin whale's blow reaches six meters height and is shaped like a slim cone. Fin whales like to leap completely above the surface of the water as they come up to breathe. Doing this enables them to dive approximately feet back down into the water.
Since a calf is not able to suckle, the mother sprays her milk into the baby's mouth. Feeding occurs throughout the day at intervals of 8 to 10 minutes. The Fin whale is the second largest animal in the world, the blue whale being the largest.
The shape of their backs and their small pointed dorsal fins have given these whales another name, which is razorback. References 1. Related Animals Antarctic Minke Whale. Bryde's Whale.

Mar 04, · The vast majority of the food consumed by fin whales are crustaceans; one estimate puts this at 98%. This is overwhelmingly comprised by krill filtered through the baleen, sometimes minimally supplemented by available capelin, eel, or other fish. Krill, Meganyctipanes norvegica / Jean-Francois St-Pierre. Fin whales have a pretty simple diet, consisting of krill, small fish and crustaceans. However, when you are that big and your prey is that small, you have to eat a lot to survive. In order to get their fill, fin whales can spend several hours each day feeding, gulping up to . Fin whales mainly eat plankton-sized animals including fish, crustaceans, and squid.
The killer whale , also known as the orca, is the largest of the dolphin family. It is a highly social mammal that lives in a pod of matrilineal members. The IUCN does not define the conservation status of the killer whale due to data deficiency, but some populations are considered endangered or threatened due to depletion of prey, habitat loss, pollution, and conflict with human fisheries.
Killer whales do not actively hunt humans, but captive orcas are known to kill or injure their handlers at marine parks. Killer whales are carnivorous, so their full-time diet consists of meat. Since they inhabit a diverse ecosystem, their eating habits vary depending on the geographical area.
Their diet ranges from small fish, seals, sea lions, rays, sea otters, turtles, dolphins, and baleen whales. Killer whales are powerful predators that are not intimidated by large animals and are capable of attacking sharks. The resident North Pacific population feeds on salmon, particularly king and chinook salmons, while the transient orcas inhabiting the same waters prefer marine mammals such as elephant seals, harbor seals, porpoises, sea lions, and minke whales.
In Norwegian waters, they go after large schools of fish, especially herring. Those in New Zealand waters prefer sharks and rays while Antarctic population feeds on seals, minke whales, and local fish. The killer whale is an apex predator that hunts without fear of being hunted. It exhibits various hunting strategies taking advantage of anatomy, strength, social behavior, and intelligence. Each prey requires a different approach depending on the size, ability to fight back, and elusiveness.
Orcas targeting schools of herring work together to create confusion by coordinating their movement and hitting the fish with their fin tails. When targeting marine mammals, orcas use their tails to hit and stun the animal or use their head to throw it into the air before delivering a fatal bite.
Large mammals such as baleen whales are more difficult to kill and require several individuals to take down calves or weak individuals. Once the target is established, the orcas isolate it from others and chase it to exhaustion. They then suffocate the whale by pinning it below the water. The strategy is also used to hunt dolphins. When hunting sea lions, sea elephants, and seals along the shallow coast, the orcas approach the shore and launch a sudden attack. Orcas also target prey resting on floating ice floes and work together to push the floes deeper into the ocean before breaking it using their tails and heads to reach the prey.
Killer whales have four rows of between teeth, which they use to grasp and tear large prey. They do not chew but instead swallow large chunks of flesh and small fish.
