 | Monotremes are warm-blooded, but they maintain their body temperature at a slightly lower level than placental mammals—usually somewhere between 86°F and 91.4°F (30–33°C). |
 | In marsupials and placental mammals, the release of milk is triggered by giving birth and is sustained by the stimulus of young sucking on a teat. |
 | The long-beaked echidna is listed as Endangered by the IUCN. |
