Lemuren

Lemuren are a diverse group of strepsirrhine primates native to Madagascar and nearby islands. In German, Lemuren is the plural form of Lemur and is used to refer to all species collectively. They range in size from the tiny gray mouse lemur, about 30 grams, to the larger diademed sifaka, up to around 9 kilograms. Distinctive features include a moist, rhinarium-like nose, a tooth comb, and, in many species, a grooming claw. Most lemurs are arboreal and rely on a combination of leaping, climbing, and slow, deliberate movement.

Lemurs belong to the suborder Strepsirrhini and diversified on Madagascar after its isolation from the Indian subcontinent. Today they are classified into four living families: Cheirogaleidae (dwarf and mouse lemurs), Lemuridae (true lemurs, including the ring-tailed lemur), Indriidae (indri, bamboo lemurs, sifakas), and Daubentoniidae (aye-aye). The aye-aye has a distinctive elongated middle finger used to extract insect larvae from wood.

Lemurs display diverse diets, including fruit, leaves, nectar, and insects. Some species are nocturnal, others diurnal or cathemeral. Reproduction is typically slow, with one offspring per year or every other year in many species, and extended parental care.

Conservation status is a major concern: habitat loss, fragmentation, hunting, and climate change threaten many species. The IUCN lists numerous lemur species as Critically Endangered or Endangered. Conservation efforts include protected areas, community-based management, habitat restoration, and captive breeding programs in zoos and research facilities.
