Posted on May 24, 2020 Steller (1751) describes Hydrodamalis as feeding on parts of algae and sea grass growing near the surface or on rocks in the shallows. Without this predation, sea urchins flourish and overgraze kelp forests.

As Roberts explains, declines in sea otters would have “triggered an ecological disaster for sea cows as urchin populations expanded and grazing pressure increased”. As the marine biologist Callum Roberts recounts in The Unnatural History of the Sea, “The rest, as they say, is history”. Animals. In June 1741, at the age of 32, Steller joined Bering on an expedition to document the natural heritage of Alaska. In The Unnatural History of the Sea, Callum Roberts says that while Bering Island was the last redoubt of the species, “its demise elsewhere was probably due to overexploitation by Indigenous peoples and loss of the sea cow’s kelp forest habitats, long before Bering’s voyages”. The last Steller’s Sea Cow supposedly died on one of the Bering Islands in 1768. The forelimbs are paddle-like flippers which aid in turning and slowing. However, translated into modern times, the wasteful killing of sea cows stands in stark similarity to the widespread habitat degradation and destruction that occurs for industrial development and urban expansion. A massive, slow moving marine mammal, Steller’s sea cow weighed up to 6 tonnes and reached lengths around 8 meters. However, it is almost always referred to as Steller’s Sea Cow. Categories.

After commercial hunting ended, some species, such as the gray whale and northern elephant seal, have rebounded in numbers; conversely, other species, such as the North Atlantic right whale, are critically endangered. Sea cow, ( Hydrodamalis gigas ), also called Steller’s sea cow, very large aquatic mammal, now extinct, that once inhabited nearshore areas of the Komandor Islands in the Bering Sea. In his book Steller’s Island: Adventures of a Pioneer Naturalist in Alaska, Dean Littlepage paints a picture of the scene as the St. Peter dropped anchor off Alaska’s Kayak Island after seven weeks at sea, and Steller, “squeezed tightly against the rail, breathed in the view of dense forests against a background of great icy peaks like gulps of oxygen for his soul”. Their speedy demise was due to rapid hunting by humans to provide meat for long sea expeditions – 1 sea cow was said to feed a ship full of men for 30 days. The Steller's sea cow grew to eight or nine meters in length. Remember that 19 ships visited Bering Island, all of which killed sea cows, but eight of them did not actually collect any of the meat from the 360 animals they killed for provisioning. It was one of the largest mammals, along with wheals, which have existed during the Holocene epoch. Although widely considered by the vast majority of scientists to be extinct, some cryptozoologists have considered it's current day survival.

We have seen that mistaken perception enacted numerous time since the sea cow’s extinction, including in fisheries and migratory birds. The Steller's sea cow would soon go extinct, with the last sighting happening in 1768. Roberts goes on to explain, “This habitat loss, as we will see, was an indirect effect of human hunting of sea otters”. Callum Roberts describes it poignantly: “Sadly, Steller shared the misfortunes of his sea cow.

For his part, Steller returned home with what remained the only detailed European description of a poorly understood, and certainly underappreciated, species. However, fossil evidence suggests that in the Pliocene and Pleistocene, it ranged from Japan to Baja California, Mexico. Commercial hunting led to the extinction of Steller's sea cow, sea mink, Japanese sea lion and the Caribbean monk seal. The Steller’s sea cow, the largest member of order Sirenia, is an extinct marine mammal. As it happened, Georg Steller left Petropavlovsk, Russia aboard the ship the St. Peter in 1741 as the expedition’s naturalist and doctor. He was born in 1709 and was described by the scientist Leonhard Stejneger, in his 1936 biography of Steller, as the “pioneer of Alaskan natural history”. Share Tweet Email. Sea otters prey on sea urchins. It belonged to a different group of mammals, known as the Sirenia, named after the mermaids of Greek mythology that were known as sirens. The sea cow lived primarily in shallow, cold waters, moving in and out from shore with the tides and grazed on kelp forests that formed its main habitat. It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century. The sea cow went extinct before we had modern methods to accurately and precisely estimate its population. Georg Wilhelm Steller spent nine months stranded on an island in the Bering Sea in 1741.

In particular, were it not for the time Steller spent observing and eating a large marine mammal during his time on the island, it is likely that the Steller’s sea cow would have been named after someone else. Idaho law aims to … Therefore, without the sea otter’s role as a predator and keystone species, the habitat balance breaks down. Much of the over hunting of the sea cow was to provision ships while on northern expeditions. When Steller visited Alaska, it is likely that intensive prehistoric hunting had already substantially restricted the sea cow’s range. Their closest living relatives are the dugong and manatees, known collectively as the sirenians. The tail fluke of a dugong is notched and similar to those of dolphins, whereas the tail fluke of manatees is paddle-shaped. Header image: Thomas Jefferys: The Russian Discoveries, from the Map Published by the Imperial Academy of St. Petersburg. Even using the much lower estimate of 1,500 individual as a reference, Turvey and Risley calculated that without wastage, the sea cow’s extinction would have been delayed until 1817. Idaho law aims to … As Steller described, “Like cattle on land, these animals live in herds together in the sea” and “are busy with nothing but their food.”. In a study published in the journal PNAS, Estes, Burdin, and Doak (2016) explain that hunting was “largely responsible for the sea cow decline at Bering Island. Share Tweet Email.

The sea cow was studied by a single scientist, Georg Steller, after whom the species is named. Weight: Estimated at between 8-10 metric tons. However, our analyses suggest that the sea cow’s extinction from this last stronghold also was a nearly inevitable consequence of the loss of sea otters and kelp forests and would have occurred without any loss of sea cows to human hunting”. While we often hear about the sea otter-sea urchin-kelp forest connection, we rarely hear about its impacts on the Steller’s sea cow. When we think about Georg Steller and the sea cow – their interactions and shared fates, and their contributions to our wider understandings of nature and conservation – their stories are interwoven in an instructive and tragic way. In his records of expeditions that hunted sea cows at Bering Island, Stejneger documented eight expeditions that did not actually provision their ships.

The final demise of the sea cow was most decidedly due to over hunting, but as Roberts explains, “their extinction is easier to understand in light of the role sea otters played in maintaining kelp forests”. Steller also happened to be a physician and a very keen naturalist. London, Printed for Robt. “Modelling sea cow extinction also highlights the catastrophic impact of wastefulness when overexploiting resources mistakenly perceived as ‘infinite’.”. His grave was robbed, his body feasted on by stray dogs, and eventually the Tura River washed away all evidence of his burial”.
