Cetacea is the same, but the study found that the structure in detail. The difference is smaller than a round head, nose, mouth small separate front teeth and molars are well developed. It is not the same as a normal tooth peak whale. The hairs on the lips, a lifetime (Good Wong Tira Valley, 2539),
the behavior of the Dugong
dugong are bundled in groups and alone, as well as the high tide and low tide. A total of flocks and herds 2-3 may find the manatee, a large crowd. And have children with Manatee At present, most will find the manatee is Australia
's food survey seagrass and dugongs observed behavior. The island Libong Trang. Dugong that will start to feed on sea grass in the water was rising. And graze on the sea for about 2-3 hours to eat sea grass and manatee come up for air every 1-2 minutes and then dive down to feed on the sea grass. Some will graze on the sea near the old while some are turning to a pool of about 1-5 meters, look at the direction of the sea, dugongs graze uncertainty. With the head turned toward the coast. Head out to sea The body is parallel to the coast Or torso angle oblique to the beach. The manatee is found mainly eat grass than one kilometer away from the coast as the water is going to live in Manatee Coast Raceway is approximately 4-5 kilometers (see the manatee in the water for about two hours after the channel) is. in accordance with the gold et al (2536)
the dugong can eat sea grass in the water day and night. The Manatee Island, Palau, mostly at night to feed on sea grass. To avoid the danger of other people and the environment. For North Queensland, Australia, found that the manatee will eat grass during the day. This will take about 30 kg of grass a day, but noted that some of the texts. 8 kg of feed per day by mouth shut or trim the plants, then the bottom line is more tenacious. Then swallow without chewing Manatee may be living resident Or seasonal migration (Kanchana peerless medicine and the support Koson, 2540)
Manatee relationship between mother and child are well. It was found that the mother and baby manatee has a very close relationship. Both while living and while swimming. Mother and baby manatee swim unsupervised near each other may be far apart, but will be in a radius of about one meter, while simultaneously breathing baby manatee up close to elephant trunk mother. Or on the back of Mom And while swimming off the seagrass will swim at the same time. The observations tracked the eating habits of the mother and baby manatee seagrass. It found that the manatee surfaced to breathe more often the mother manatee. While the mother manatee eating the sea grass. Baby manatee surfaced breathing 2-3 times, so the mother manatee surfaced to breathe a
reproduction of Dugong
dugong breeding is not seasonal. Are pregnant for 13-15 months (some texts indicate that approximately 385-400 days) to produce the first time (some texts indicate that the ball has reached a second time, but there are very few) have an average weight. 20 kilograms (Journal of Fisheries Weight about 20-35 kilograms) by the dugong, emerging with a maximum weight of 100 kg, the mother will have to push the ball up to the surface immediately. Then put them on his back in the beginning. After giving birth to my children breathe and the water discharge. It will gradually rise and sink yourself into a rhythm
habitats and habits of Dugong
dugong is living in a coastal area outside the brackish water. She lives in the coastal waters and
shallow rather than deep water, or up to 10 meters (average depth is found in approximately 3-5 meters) area not far from the sea grass and the wind is not organized. Sometimes found in mangroves, brackish water into the canals usually have to live underwater. It appeared on the surface to breathe air every 3-5 minutes (some books say that to emerge every 6-16 minutes) will be submerged in water at all times. Usually there will be a steady rise in parallel with the ground water. Moving slowly Habit peacefully, whether it is a crowd or alone. But mostly, it is the masses. Can coexist with fish and other aquatic life, but if someone or something else is bothering him to dive to escape quickly. Payoon will appear on the surface to breathe air every 3-5 minutes,
being able to move
dugongs can swim as fast as normal, about 10 kilometers per hour. And will swim up to 20 mph. In times of panic or avoid abnormal
status of dugongs around the world
, although dugong is a protected species in Australia. But still it is allowed to hunt the old faith tradition of the aboriginal. And Torres Strait Islander Manatee often live in seagrass beds. This day will be destroyed forever. The dredging Soil erosion from agricultural areas into the sea. And often harmed by such large nets or trawl nets, sharks, stingrays, which are similar to the problems of dugongs, dolphins. For example, in Great Barrior Reef (GBR) has a population of approximately 3,500 dugongs (in 1987) and four years later (in 1991), the dugong population dropped to 1700 reduced the population very quickly. It is in a state of near extinction. It is evident that the problem is similar to the manatee, dolphins is decreased dramatically worldwide
dolphins
dolphins. The mammalian milk, water with high intelligence one. The descent close to the whale in English that called Dolphin Dolphin comes from the Ancient Greek δελφίς del Memphis (delphis) Greek legend has it that the name of the Greek god of wine Dione sauce (Dionysos) transforms into a man.
