Two endangered monkey species give birth to twins at Straubing Zoo. The two marmoset species are considered critically endangered.

There are only 1,000 golden lion tamarins left in the world. The monkeys with the white fuzzy heads owe their unusual name to the Austro-Hungarian composer Franz Liszt. It is currently unclear what gender the two monkeys are. As early as 2023, the zoo pointed out that this could often take a few weeks. As of: April 5, 2024, 5:09 p.m.
