Dugong

2008). Its humerus is closest to the body, thin and long in comparison to other mammals (Meyers et al 2014). Their radius is attached to the humerus and it is a long and thin nonetheless also a strong bone that supports the wing, while the ulna is reduced and fused with radius (Meyers et al 2014). Chiroptera wrists have been modified to support motions that deals with flying but has reduced flexible compared to other mammals (Meyers et al 2014). The bait forelimbs may be also used for climbing, defense, and for eating. This is allowed by their thumb that is located at the edge of the wing, containing a claw (Meyers et al 2014). Their wings membrane is an extension of their skin of their body which contains hairs (Meyers et al 2014). Dugong dugon commonly known as sea cows, are in order sirenia and family dugongidae. Their forelimbs main functions have evolved for swimming. They have a fusiform body shape. Their forelimbs are paddle like flippers and are used for turning and slowing (Chew 2009). They also lack hind limbs, dorsal fins and some lack nails (Domning 2001). Their limbs contain five sets of fingerlike bones (Kanai 2014). They are able to pull their body forward in shallow water because of their forelimbs (Berta et al 2006). Another function their forelimb is used for is feeding; they use their thick flippers to turn the seabed during feeding (Chew 2009). Some think that because of their fingerlike bones and ability to turn their head they may have been…

The Torres Strait Islander bone mounds are the subject of much speculation and research. The connection between the mounds and the Islanders who created them has formed the core of discussions on this subject. In this essay I will examine the usage of both archaeological practices and archaeological theory in relation to animal bone discovery. My focus will be on dugong bones in particular; looking at the pattern of sustainability their hunting has endured over time. I will assess the methods…

The Great Barrier Reef's inhabitants are most vulnerable to the impacts of climate change that alter their communities, habitat and food sources. All the species are equally important so they all had to figure out a way to survive anything to global warming to the yearly cold winters. There are about 15 different species of whale in the Great Barrier Reef alone, most of them migrate north while the southern hemisphere have their winter to breed. So while they are staying at the Great Barrier…

Most of the world’s dugong population now occurs in northern Australian waters between Shark Bay in Western Australia and Moreton Bay in Queensland. It is listed under the IUCN - the World Conservation Union - Red List of Threatened Animals. The Crown of Thorns starfish is one of the biggest invaders of the reef to date. Cyclic outbreaks of the crown-of-thorns starfish occur approximately every 17 years. There have been four documented outbreaks on the Great Barrier Reef since the 1960.…

more water to help Queensland in the drought. The proposal was formed in 2006 and was stopped in November of 2009. The dam would have affected major transport including the Bruce Highway. Residents who lived near the proposed area were not happy with the proposal. The wider community had concerns related to the endangered Mary River Cod, Mary River Turtle, Giant Barred Frog, Cascade Tree Frog, the vulnerable Lungfish, Tusked Frog, Honey Blue-Eye Fish. There were also concerns for the dugong. 2.…

Biotic factors are the living organisms of an ecosystem, the Bay has approximately 757 native species including, 398 birds, 97 reptiles and over 2344 plants (…). Moreton bay has a rich diversity of biotic and abiotic factors which interact with each other. Extensive mangroves and tidal flats support and shelter fish, birds and other wildlife (State of Queensland, 2015). Sandflats provide roosting sites for migratory birds and seagrass beds nurture fish, shellfish, dugong and turtles (State of…

The GBR’s coral rarely grow lower than 40 meters below sea level since sunlight passes through shallow and clear waters. It has no real soil, being a marine coral ecosystem, but loose carbonate mud covers 135,000 square miles of land. Its biotic factors are animals & plants. It is highly diverse, with 1,500 fish species, hundreds of types of corals, 500 algae species, and many sharks, rays, marine mammals, crustaceans, and echinoderms. Animals like the dugong, butterfly fish, jellyfish, green…

seeks a resort experience farther away from the shoreline. Other common structures include pontoons and underwater observatories. Vessel-based activity are site-specific, where the brokers will take the tourists on a rover and bring them to specific sites. In some cases, this type of activity may take up to weeks, and in which case, it would be subcategorized as extended vessel-based activity. Bareboat charter is probably the most cliché activity. This is the familiar yachting that we often see…

The scientific order Sirenia, which is classified as marine mammals, has only two extant families. The first family contains the manatees (Trichechidae). In this family, there are three different species which are the West Indian manatees (Trichechus manatus), African manatees (Trichechus senegalensis), and Amazonian manatees (Trichechus inunguis). The second family (Dugongidae), contains only one species which is the dugong (Dugong dugon). This paper will focus on manatees. On average, manatees…
