袋鼠和兔子
袋鼠和兔子是生活在不同地方的非常独特的动物。他们有一些共同的特点,但差异更突出。这两者的分布、多样性和体型主要不同。然而,本文讨论了一些重要的和有趣的,有些不常见的字符。
袋鼠
袋鼠是袋鼠科最大的有袋类动物。它们只在澳大利亚有,其他地方没有。在澳大利亚的母语中,他们被称为“Gungurru”,英语发音变成了袋鼠。男性被称为Buck或Boom或Old Man,而女性被称为Doe或Flyer或Jill。袋鼠非常适应干旱的环境,因为它们可以在沙漠中几个月不喝水的情况下生存。袋鼠有40多种,它们的皮毛颜色和体型大小各不相同。红袋鼠是所有袋鼠中最大的。它们是一种后肢特别大的跳跃动物。跳跃速度可高达每小时70公里,这有助于它们免受捕食者的伤害。袋鼠是一种草食性哺乳动物,可以依赖于各种各样的草,它们的牙齿适合放牧。 Almost all of them are social animals live in groups called Mobs. During their reproduction period males show flehman reaction to detect the females in heat. Females deliver a neonate after thirty days of the gestation. It develops inside the female’s characteristic pouch for about seven months by suckling milk. After about 190 days the baby, called Joey, sticks out its head and within about 1 – 2 months from there, Joey will be ready to be released from the pouch. Females are said to be ever pregnant because they become sexually receptive soon after a neonate is delivered into the pouch. This wonderful and unique animal is a real appreciative creation of the Mother Nature.
兔子
兔子是一种小型草食性哺乳动物,隶属于兔形目:兔形科。有八个不同的属,超过50种。它们的雄性被称为雄鹿,雌性被称为雌鹿,年幼的被称为基特或小猫。它们可以生活在各种各样的栖息地,包括湿地、森林和干草地。一般来说,它们把地下洞穴作为自己的家。它们在世界上几乎所有地方都有,但在澳大利亚却没有。在澳大利亚,它是一种入侵物种,作为害虫也造成了很多问题。它们的耳朵特别长,可以更早地发现捕食者。兔子的尾巴很短,它们有短但强壮的腿,这有助于它们在紧急情况下快速跳跃。体长在20到50厘米之间,体重在0.5到2公斤之间。 They vary in coat colour depending on the species. Some have short fur coat but some are with very long fur coat depending on the climate. Rabbits have two sets of incisor teeth one behind the other, which rodents don’t have. Sometimes rabbits stand up from two hind legs to reach the tall grasses appearing like a small kangaroo. Rabbits are hind gut fermenters, meaning their digestion of food takes place at caecum. Other interesting character of rabbits is the coprophagous behaviour, i.e. they eat their own faeces. However, their breeding is superfast as they can get pregnant in every 30 days and the litter size could be from 4 – 12 kits.
