The Lisztaffe ( Saguinus oedipus ) is a primate from the marmoset family . The common German-language name caricatures the similarity of his hairstyle with that of the Austro-Hungarian composer Franz Liszt .
features
Lisztaffen reach a head body length of 21 to 26 centimeters, the tail is with 33 to 41 centimeters longer than the body. The weight is 300 to 450 grams. Their fur is brown on the back and shoulders, and whitish-yellow on the abdomen and limbs. As with all marmosets, the fingers and toes (with the exception of the big toe) have claws instead of nails. The long tail is reddish-brown at the root and turns black towards the tip. The most outstanding characteristic is the long, white hair that hangs from the head over the shoulders.
distribution and habitat
Lisztaffen are only native to northwestern Colombia , where they are found in the region on the Caribbean coast . Their habitat is forests, whereby they can be found both in rain forests and in drier forest forms. You are dependent on areas with dense undergrowth.
Lifestyle and diet
Like all marmosets, the whiskeys are diurnal tree dwellers. In the branches they move on all fours or jump.
These animals live together in groups of three to nine animals, which consist of a dominant, monogamous couple, their offspring and mostly other subordinate younger animals. One group lives in an area of 7 to 10 hectares, which is marked with glandular secretions. They intimidate intruders from other groups by clearly displaying their anal and genital areas.
The diet of the Lisztaffen mainly consists of insects and fruits, in addition they also eat small vertebrates and tree sap.
Reproduction
Usually only the dominant pair in a group will breed. Twice a year the female gives birth to two young animals after around 140 days of gestation. First and foremost, the father takes care of the offspring, he carries them on his back and only brings them to the mother to suckle. The other group members also take care of the young animals. The young are weaned after around three months, females reach sexual maturity after 18 months and males after 24 months. Life expectancy is around 10 years.
Danger
In the 1960s and 1970s, thousands of animals were caught and exported to the United States as laboratory animals . This practice is forbidden today, instead the progressive destruction of their habitat is the biggest problem. There are three protected areas, but the implementation of species protection is often not guaranteed. The IUCN estimates that in the last 18 years (three generations) the total population has declined by over 80% and lists the species as " critically endangered ". The total population is around 6000 animals, 2000 of them adult.
Systematics
The Lisztaffe, together with the Geoffroy wig monkey and the white-footed tamarin, form the oedipus group within the genus of the tamarins ( Saguinus ). The oedipus group is geographically isolated from the rest of the tamarins, as they do not live in the Amazon basin like the other species , but in north-western Colombia and Panama .
