How many baby Amami rabbits are in a litter?
A Amami rabbit (Pentalagus furnessi) usually gives birth to around 2 babies.
Upon birth, they weight 253 grams (0.56 lbs) and measure 7.8 cm (0′ 4″). They are a member of the Leporidae family (genus: Pentalagus). An adult Amami rabbit grows up to a size of 44.4 cm (1′ 6″).
To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.
The Amami rabbit (Pentalagus furnessi; Amami: [ʔosaɡi]), or Amamino kuro usagi (アマミノクロウサギ 奄美野黒兔, lit. “Amami wild black rabbit”), also known as the Ryukyu rabbit is a dark-furred rabbit which is only found in Amami Ōshima and Toku-no-Shima, two small islands between southern Kyūshū and Okinawa in Kagoshima Prefecture (but actually closer to Okinawa) in Japan. Often called a living fossil, the Amami rabbit is a living remnant of ancient rabbits that once lived on the Asian mainland, where they died out, remaining only on the two small Japanese islands where they live today.
