Visi ... and was responsible for the highest record of dugong strandings following the Queensland 2010/11 summer of floods, You can help right now by contributing to WWF-Australia's. [16] The number of growth layer groups in a tusk indicates the age of a dugong,[10] and the cheekteeth move forward with age. When eating they ingest the whole plant, including the roots,[15] although when this is impossible they will feed on just the leaves. This is ideal for recovery after an attack by another male, or a predator. [20] The flexible and muscular upper lip is used to dig out the plants. Thank you! Its snout is sharply downturned, an adaptation for feeding in benthic seagrass communities. [15] Food shortages can be caused by many factors, such as a loss of habitat, death and decline in quality of seagrass, and a disturbance of feeding caused by human activity. The molar teeth are simple and peg-like unlike the more elaborate molar dentition of manatees. The Memorandum of Understanding on the conservation and management of dugongs and their habitats throughout their range, under the auspice of the convention of migratory species of wild animals, is viewed by all signatory states as a crucial mechanism to preserve this species.

On the east coast of Queensland, we estimate that each year commercial gillnetting entangles around 50 of these majestic animals, so it's a significant threat to declining populations. [89] The age when a female first gives birth is disputed, with some studies placing the age between ten and seventeen years, while others place it as early as six years. A highly isolated population lives around the islands of Palau. Daily movement is affected by the tides. The dugong is the only strictly herbivorous marine mammal. The main cause of this loss is human activity. [10], Mating behaviour varies between populations located in different areas. As such, trends are uncertain, with more data needed for comprehensive management.

[17] They will dig up an entire plant and then shake it to remove the sand before eating it. [15] There is not yet sufficient genetic data to make clear boundaries between distinct groups. The two extant families of sirenians are thought to have diverged in the mid-Eocene, after which the dugongs and their closest relative, the Steller's sea cow, split off from a common ancestor in the Miocene. [95] One of the three individuals has not been observed since June 2015, corresponding to the start of the excavation operations. [15] Dugongs and elephants share a monophyletic group with hyraxes and the aardvark, one of the earliest offshoots of eutherians.
