| | Monotreme - Wikipedia, the free encyclopedia |
 | | The monotremes also have extra bones in the shoulder girdle, including an interclavicle, which are not found in other mammals. | | | The key physiological difference between monotremes and other mammals is the one that gave them their name; Monotreme means 'single opening' in Greek, and comes from the fact that their urinary, defecatory, and reproductive systems all open into a single duct, the cloaca. | | | As in all true mammals, the tiny bones that conduct sound to the inner ear are fully incorporated into the skull, rather than lying in the jaw as in cynodonts and other pre-mammalian synapsids; however this feature too is now claimed to have evolved independently in monotremes and therians (Rich et al, 2005). |

| | As that taxon is otherwise anatomically more primitive than any monotremes, a similar separation seems to have taken place at least three times; in the ancestors of Hadro, in my predecessors and within Monotremata. | | | As Woodburne's paper is concerned specifically with monotremes, I'll attempt to utilize his observations to enrich the entries as appropriate. | | | Whether it's a very basal monotreme or something else is presently unclear. |

| | eyeteeth: Their cousin called monotreme |
| | Monotremes are mammalian, even if what they have is a kind of free demo version of mammalianism without the really useful features like live birth, so they lactate. | | | The platypus uses it to avoid predators and find prey underwater (their already poor eyesight is almost useless there), while the echidnas can actually sense the bioelectricity of individual ants when burrowing into their nests for food. | | | A some point, a monotreme branch evolved wombs and found itself very successful. |

| | Bonus point if you can define what is a monotreme. | | | Monotremes are not able to control their body temperature as well as marsupial and placental mammals (and birds), but their body temperature is less influenced by the outside temperature than is the case in cold blooded vertebrates such as reptiles. |

| | Mammals - Monotreme |
| | Nonetheless monotremes may well represent features of anatomy and development that characterized the earliest mainstream mammals. | | | The three living monotremes are the platypus (Ornithorhynchus anatinus), one of the most remarkable of all mammals with its ducklike "bill," webbed feet, and a flattened beaverlike tail, and the echidnas, or spiny anteaters (Tachyglossus aculeatus and Zaglossus bruijni), which have sharp-pointed spines and tubelike noses. | | | These are, in fact, the only monotremes still in existence and the only surviving members of the subclass Prototheria. |

| | Introduction to the Monotremata |
| | In some ways, monotremes are very primitive for mammals because, like reptiles and birds, they lay eggs rather than having live birth. | | | Monotremes are not a very diverse group today, and there has not been much fossil information known until rather recently. | | | There are only three living monotremes, the duck-billed platypus and two species of echidna, or "spiny anteaters," such as the one shown at left. |

| | Monotreme Order |
| | Although the Monotremes posses typical mammalian features, such as hair on their bodies, and the ability to produce milk to feed their young, they are in many ways very different from the rest of the mammals. | | | The other family, the Tachyglossidae is made up of three species of echidnas, or spiny anteaters. | | | The most extreme of these differences is the fact that they do not give birth to live young like the rest of the mammals, but lay eggs instead. |
