Faculty, Staff, and Students, It is hard to believe that another school year is winding down so quickly. With my visits to classrooms, meeting rooms, and extra-curricluar events during the school year, I have noticed the great work each of you are doing. Students, employees, and parents have been eager to share with me so many great stories about the collective work happening in our school district.
When Australia separated from the ancient super-continent, many marsupial species got isolated on Australia, and then diversified into many more species that fill a variety of ecological niches. As a result, there are more species of marsupials in Australia than anywhere else in the world-- about 144 species (Bennett, 2000). Marsupials are mammals: they have fur, bear live young rather than laying eggs, feed their young with mother's milk from a nipple, and show quite a bit of parental care --sometimes for longer than a year. What makes marsupials unique among mammals is the female's pouch where the young finish their development after birth. A young marsupial is born after only a few weeks as an embryo. It may be less than one centimeter in length and very helpless. It has large front paws that it uses to climb through the mother's fur to reach the pouch.
Marsupials are found on several of the continents. Australia is the continent on which 99% of the world's marsupials live. The opossum is a marsupial found in North America, â¦ but South America also has some marsupials, as does Asia.Some marsupials such as possums and tree kangaroos are also found on the island of New Guinea, which is not a continent.+ 12 others found this useful.he opossum is a marsupial found in North America, â¦ but South America also has some marsupials, as does Asia.
