Friday 23 February 2007 Order monotremata

The order of monotremes (Monotremata) consists of all mammals (5 species in total) that lay eggs instead of giving birth to live young. Unlike the difference in their reproductive system, they share some similarities with other mammals: they are warm-blooded, have a relatively high metabolism, produce milk for their young, have a single bone in their lower jaw and have 3 middle ear bones (source). Monotremes have a lower body temperature than other mammals, the short-beaked echidna can 'turn off' its body regulating mechanism to keep its energy during colder weather. Today, all living members of Monotremata live in Australia and New Guinea.

Interesting fact: The name 'Monotreme' means 'single opening', because members of the order of Monotremata all just have one opening when other female mammals have three (vagina, the urethra, and the anus).

Wednesday 21 February 2007 Binturong

The Binturong (Arctictis binturong) lives in South-east Asia. Despite all its other names like 'Asian Bearcat', 'Malay Civet Cat', 'Palawan Bearcat' or 'Bearcat', it is actually a species of civet. Due to habitat destruction and poaching for its fur or for medicine, the Binturong is endangered. They are nocturnal and sleep on branches. They are slow moving arboreal animals feeding mainly on fruit.

Interesting fact: The scent of Binturong musk smells like warm popcorn and cornbread.
Another interesting fact: Female Binturongs are believed to be capable of timing the birth of their young, called 'Embryonic diapause'.

Monday 12 February 2007 Domestic sheep

The domestic sheep (Ovis aries) descends from the Mouflon, and in 2003 evidence is proposed that Ovis aries first got domesticated about 9000 BC in Iraq and has been a source of meat, milk, wool and hides since then. There still exist two populations of wild Mouflons: the Asiatic Mouflon and the European Mouflon, although the last may be feral as some sources suggest. The domestic sheep has a highly developed herding or flocking instinct, there is no leader among the sheep. This is quite an advantage, as a shepherd is able to control a large group of sheep. Ovis Aries has a complex stomach system which allows it to digest highly fibrous food that many other mammals cannot. Estimates are there are over 1 billion sheep in the world. The Oklahoma State University has an excellent page with all different breeds of sheep (282).
