Defence. Dugongs are slow-moving and have little protection against predators. Being large animals, however, only large sharks, saltwater crocodiles and killer whales are a danger to them. Young dugongs hide behind their mothers when in danger.

What kills a dugong?
The main cause of mortality over that period was drowning in fishing nets (72.5%), followed by vessel strikes (15.7%). But look at the last five years also, and death by drowning emerges as an even more dominant cause, responsible for 85% of dugong deaths.
What are the dugongs threats?
Threats. Dugongs are threatened by sea grass habitat loss or degradation because of coastal development or industrial activities that cause water pollution. If there is not enough sea grass to eat then the dugong does not breed normally. This makes the conservation of their shallow water marine habitat very important.
Do whales eat dugongs?
Dugongs are natural prey for sharks, killer whales and crocodiles, but they are most vulnerable to human activities.
Do reef sharks eat dugongs?
Unlike the closely related manatees, the dugong never enters freshwater and is therefore the only exclusively marine mammal that is herbivorous. ... Adult dugongs do not have any natural predators, but juveniles may be eaten by saltwater crocodiles, killer whales, and large, coastal sharks.
What eats dugongs in the Great Barrier Reef?
They have few predators, besides sharks, crocodiles and man. Dugongs were hunted to the edge of extinction in the early part of last century by Europeans for food and oil. These days, dugongs are under pressure from other activities, such as loss of habitat, boat traffic and being caught in fishing nets.
What eats a sea turtle?
The Problem: Around the globe, sea turtles and their hatchlings fall victim to natural predators. Crabs, raccoons, boars, birds, coyotes and sharks all play their role in the natural food chain as sea turtle predators. However, the threats of predation increase when human development reaches nesting beaches.
How can we protect dugongs?
Whether in protection areas or not, take care to avoid injuring or distressing dugongs. Protect habitat: Avoid damaging seagrass an don't drag boats over seagrass meadows. Take action to prevent pollutants, nutrients and herbicides from agriculture and other land-based activities flowing into creeks and rivers.
What would happen if dugongs went extinct?
Abu Dhabi If dugongs become extinct, the impact will not be limited merely to the fact that future generations will not get to see the marine mammal — their absence will almost surely have an impact on the availability of sea fish, the staple diet of millions of people across the world.
How does global warming affect dugongs?
Dugongs may experience indirect effects of climate change and human activity through impacts on their main food source, seagrass. Seagrass diebacks are linked to lower reproduction, increased mortality and emigration of dugongs.
Do dugongs have predators?
Defence. Dugongs are slow-moving and have little protection against predators. Being large animals, however, only large sharks, saltwater crocodiles and killer whales are a danger to them. Young dugongs hide behind their mothers when in danger.
Do orcas eat walruses?
Orcas hunt everything from fish to walruses, seals, sea lions, penguins, squid, sea turtles, sharks, and even other kinds of whales. Depending on the season and where they are, their diet varies—some orcas eat more fishes and squid than seals and penguins.
Does anything eat a shark?
Though the great white is considered the top marine predator, orcas may actually rule the oceans, new observations suggest.
Who eats killer whales?
Killer whales are apex predators, which means they have no natural predators. They hunt in packs, much like wolves, which are also at the top of their food chain.
What eats a coral?
In addition to weather, corals are vulnerable to predation. Fish, marine worms, barnacles, crabs, snails and sea stars all prey on the soft inner tissues of coral polyps.
