Dugongs natural predators include...?
Correct Answer
D. All of the above
Explanation
Sharks found in tropical waters, salt water crocodiles and killer whales have all been known to attack and kill dugongs. Dugong young are particularly vunerable, more so than adults. However, by far the biggest threat to Dugongs is from human activities. C3 has found fishers gill nets pose the highest risk for Dugongs in West Indian Ocean through accidental capture!
2.
Sailors used to believe Dugongs were...?
Correct Answer
A. Sirens
Explanation
The dugong and the manatee are related to the myth of sirens, enough to be classified in the order of Sirenians (or Sirenidae). The myth of sirens dates back to the civilization of ancient Greece. Among theories as to why this came about is the fact that the female dugong has her teats very close to the base of her flippers: often, while suckling, she holds her baby tight on her breast using her flippers, thus reminding sailors of a woman breast feeding!
3.
A typical Dugong dive lasts...?
Correct Answer
A. 1-3 minutes
Explanation
Unlike other marine mammals, dugongs cannot hold their breath under water for very long. As their food source, seagrass, lives in shallow water they have no need to dive deep, this also means however they are more susceptable to accidental boat strikes as they spend most of their time near the surface!

In Madagascar, it is considered taboo to allow pregnant women any knowledge of a Dugong capture?
Correct Answer
A. True
Explanation
C3 has discovered that many different taboos, or 'fadys' exist in Madagascar surrounding the Dugong, varying between individuals and community groups. Many fadys are associated with the sex organs of dugongs. It is a widespread belief that fishermen who have captured a dugong must swear that they have not had intercourse with it. At all times following capture, including during the slaughter, the genitals, teats and head must be covered from the general public, particularly women and children, to prevent discussion about the event. This is of particular importance for pregnant women.

6.
Dugongs are listed as ...... on the IUCN Red List of Threatened species
Correct Answer
B. Vulnerable
Explanation
The dugong’s range spans at least 48 countries and an estimated 140,000 km of coastline. The IUCN synthesis indicates that the dugong is declining or extinct in at least a third of its range, of unknown status in about half its range and possibly stable in the remainder – mainly the remote coasts of the Northern Territory and Western Australia. C3 has found evidence to suggest Dugongs are still present in some areas of Northern Madagascar but numbers have declined significantly in the last 20 years. If work doesnt continue to protect these remaining Dugongs the species will vanish from these water altogether!

Since June 2009 C3 has conducted over...... key informant interviews to gather data on the status, distribution, threats and socio-economic and cultural values of Dugongs in Northern Madagascar?
Correct Answer
C. 600
Explanation
C3's work shows that although Dugongs were present in large numbers in the past, the population has been in decline, particularly since the 1990s. Deliberate hunting is no longer commonplace, instead accidental capture in gill nets poses the greatest threat to the continuance of the species in the area.
