The jaw and dental morphology of Palaeolama species distinguish them from other laminae. They tend to have a comparatively more dorsoventrally gracile mandible. [4] [2] Like Hemiauchenia, Palaeolama species lack second deciduous premolars and can further be differentiated by the distinct size and shape of their third deciduous premolars.
While not considered an endangered species in southern Argentina and Chile, dead guanacos are a common sight throughout this region where they are entangled on fences. Studies have found that annual yearling mortality on fences (5.53%) was higher than adult mortality (0.84%) and was more frequent in ovine (93 cm high) than bovine (113 cm) fences.
Some llamas retire before that and some continue to work even at 20 or 21, Hamilton said. At the LeConte Lodge, the decision happens on a case-by-case basis that prioritizes each llama's well-being.
Dromedary camels, bactrian camels, llamas, and alpacas are all induced ovulators. [8] The three Afro-Asian camel species have developed extensive adaptations to their lives in harsh, near-waterless environments. Wild populations of the Bactrian camel are even able to drink brackish water, and some herds live in nuclear test areas. [9]
The most common hybrid between South American camelids, [1] huarizo tend to be much smaller than llamas, with their fibre being longer. [2] Huarizo are sterile, but recent genetic research conducted at the University of Minnesota Rochester suggests that it may be possible to preserve fertility with minimal genetic modification .
[9] [10] [11] This type of reproduction has been induced artificially in a number of animal species that naturally reproduce through sex, including fish, amphibians, and mice. [ 12 ] [ 13 ] Some species reproduce exclusively by parthenogenesis (such as the bdelloid rotifers ), while others can switch between sexual reproduction and parthenogenesis.
Llama crias are typically born with the whole herd gathering around (only the females are present, as the males are considered a threat) in an attempt to protect against potential predators. Llamas give birth standing, and the process is usually relatively quick and problem-free, over in less than 30 minutes.
