Australia is home to the largest population, stretching from Shark Bay in Western Australia to Moreton Bay in Queensland. The population of Shark Bay is thought to be stable with over 10,000 dugongs. Smaller populations exist up the coast, including one in Ashmore Reef. Large numbers of dugongs live to the north of the Northern Territory, with a po...
The Persian Gulf has the second-largest dugong population in the world, inhabiting most of the southern coast, and the current population is believed to range from 5,800 to 7,300. In the course of a study carried out in 1986 and 1999 on the Persian Gulf, the largest reported group sighting was made of more than 600 individuals to the west of Qatar....
In the late 1960s, herds of up to 500 dugongs were observed off the coast of East Africa and nearby islands. Current populations in this area are extremely small, numbering 50 and below, and it is thought likely they will become extinct. The eastern side of the Red Sea is home to large populations numbering in the hundreds, and similar populations ...
A small population existed along the southern coast of China, particularly the Gulf of Tonkin (Beibu Gulf), where efforts were made to protect it, including the establishment of a seagrass sanctuary for dugong and other endangered marine fauna ranging in Guangxi. Despite these efforts, numbers continued to decrease, and in 2007 it was reported that...
Today, possibly the smallest and northernmost population of dugongs exists around the Ryukyu islands, and a population formerly existed off Taiwan. An endangered population of 50 or fewer dugongs, possibly as few as three individuals, survives around Okinawa. New sightings of a cow and calf have been reported in 2017, indicating a possible breeding...
It has been confirmed that dugongs once inhabited the water of the Mediterranean possibly until after the rise of civilizations along the inland sea. This population possibly shared ancestry with the Red Sea population, and the Mediterranean population had never been large due to geographical factors and climate changes. The Mediterranean is the re...
All mammals have hair, although the amount of hair varies greatly among the various mammal groups. Cetaceans and sirenians appear almost hairless while the marine carnivorans—pinnipeds, polar bear, sea otter, and marine otter—are covered with thick fur.
This group includes 11 species ranging in length from the pygmy right whale at 21 feet (6.4 m) to the largest whale, the blue whale, at 100 feet (30.5 m). Baleen whales have two blowholes and instead of teeth, they have hundreds of rows of baleen plates, which are made of keratin, a substance in our hair and fingernails.
Whales are mammals which means that, like humans and other land mammals, they have three inner ear bones and hair, they breathe air, and the females produce milk through mammary glands and suckle their young.
Blue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the oceans at up to 100 feet long and upwards of 200 tons. Their tongues alone...

Dec 5, 2023 · Baleen whales are part of the cetacean infraorder, along with porpoises, dolphins, and toothed whales. These large marine mammals—which include the largest animals on Earth—live exclusively in water and can be found in every ocean on the planet, from temperate seas to the freezing waters of the Arctic and Antarctic.
