The Sei Whale (pronounced /ˈseɪ/ or /ˈsaɪ/), Balaenoptera borealis, is a baleen whale, the third-largest rorqual after the Blue Whale and the Fin Whale. Estimates state that as much as 400,000 tonnes of carbon are extracted from the air due to these whales each year! These whales communicate with growl-like low-frequency calls. The sei whale population was decimated by commercial whaling in the 1800s and early 1900s. Phytoplankton helps feed the fish allowing them to thrive and reproduce, and the fish feed many other species that require fish to survive, thus keeping the food chain stable. At first it may appear that other species are benefiting from no longer having to face a predator such as whales, but over time these animals will overpopulate and possibly destroy the population of other species that it feeds on, so whales play an important role in maintaining the balance of the ecosystem by making sure other species do not overpopulate and destroy the species below them in the food chain. A summary of their responses follows. [3] It can be found worldwide in all oceans and adjoining seas, and prefers deep off-shore waters. Sei whales occur in subtropical, temperate, and subpolar waters around the world. ... Why do we need whales? The oil rendered from the blubber of baleen whales was used to produce soap, margarine and other foodstuffs. Whales are at the top of the food chain and have an important role in the overall health of the marine environment. Today however commercial whaling activities are illegal and those caught hunting whales may face steep fines and jail time. They have, however, been known to feed on small schools of fish and even squid. When it comes to the environment and the oceans ecosystem whales help regulate the flow of food by helping to maintain a stable food chain and ensuring that certain animal species do not overpopulate the ocean. Sei whales occur in subtropical, temperate, and subpolar waters around the world. Sei whales are one of the fastest swimming cetaceans and can reach speeds of 31 mph. The Sei whale (Balaenoptera borealis) is a dark-gray, stream-lined baleen whale that is found worldwide except in polar waters. In 2007, three blue whales died in a very short period of time near California after being hit by boats. The third largest whale species after blue whales and fin whales, sei whales are one of the most poorly understood of all ... animaldiversity.org › accounts › Balaenoptera_borealis. They have some characteristics that make them quite familiar in various ways. Without the existence of the whale species the entire worlds economy would see a huge negative shift and everyone and everything would be affected from this change. Roy Chapman Andrews, the American naturalist, compares Sei whales to the cheetah because, although they are able to swim very quickly for a … This understanding of whale intelligence has brought new insights into the importance of caring for these marine mammals and granting them certain protective rights so that they can continue to thrive in the ocean. [4] It tends to avoid polar and tropical waters and semi-enclosed bodies of water. Whales play a significant role in capturing carbon from the atmosphere; each great whale sequesters an estimated 33 tons of CO2 on average, thus playing their part in … It inhabits most oceans and adjoining seas, and prefers deep offshore waters. One of their least appreciated contributions is their positive impact on carbon sequestration. Females are usually a bit larger. Sei whale. 1) The sei whale is the 3rd largest living animal on this planet after the blue whale and fin whale. In additional to feeding carbon fighting phytoplankton the fact that whale poop stimulates the growth of phytoplankton means that it also helps feed other species that feed on phytoplankton for their survival.

Like all whales, Sei Whales also suffer from commercial hunting and whaling. It has also educated us on how man made sounds may be affecting the echolocation abilities of other marine animals so that we can try to develop ways to better protect them from harmful man made noise, either by enforcing laws or creating new technology that doesn’t interfere with marine mammal echolocation. The Blue Whale belongs to the baleen category. Blue whale, a species of baleen whale, a cetacean, that i sei whale sounds December 2, 2020 99 [54] These whales are known for creating very loud low-pitched sounds.

These include the sei, blue, fin, sperm, northern right whales and some sub-populations of humpback whales - notably the Oceania population that includes Eastern Australian humpback whales. Sei whales are large whales reaching almost 19.5 meters (64 feet) long. It has very fine grey-black baleen that traps very small particles of food. Whale parts and oil were sold and used for many different things including soap, margarine, corset material and transmission oil additives. In some ways this is akin to the way humans, elephants and primates live. Whales belong to the order cetacea, which means that they are mammals fully adapted to aquatic life.Like all cetaceans, including dolphins and porpoises, whales are descendants of land-living animals which returned to water after living millions of years in land. Not all baleen whales migrate; Bryde's whale, the bowhead whale and sei whale are all non-migratory. They are currently endangered and are protected by a worldwide ban on commercial whaling.

Depending on the whales species some marine mammals are known to spend the majority of their lives together and will hunt with one another and protect each other from harm. In order to give you a greater understanding of their importance we’ll begin by looking at how whales have helped us develop our understanding of marine mammals and why this understanding has led to new perspectives on the care of various marine mammals. Whales play a very important role in the health of our environment and our understanding of marine mammals as well as playing an important role in helping growing economies that rely on whale watching and other spectator activities bring in capital through tourism. It has between 30 and 60 ventral pleats in its throat. When one species of animal that is important to the food chain dies it allows other species to thrive. Introduction to Whales. Sei Whale . Sei Whales are one of the fastest of all cetaceans (Whales, Dolphins, and Porpoises), able to reach speeds of up to 50 mph for short sprints. Our growing understanding of whales is important for improving the safety measures of all marine mammals as well as improving the oceans ecosystem. Sei whales are baleen whales; they have a series of fringed, overlapping plates that hang from the upper jaw where teeth would be. When it comes to communication whales have a very complex language which is so sophisticated some researchers believe that we may be able to communicate with them if we can understand what they are saying and develop the technology necessary to have a conversation or at least communicate our interests with other cetaceans. Whale poop plays a large role in stabilizing the offset of carbon in the atmosphere providing a healthier environment for both land and aquatic lifeforms. Next we’ll take a look at how whales affect our environment and the oceans ecosystem and end with how they help growing economies bring in extra money through tourism and local events.
