Unfortunately, their calculations of Ming's age weren't possible without cracking open the clam's shell, so researchers didn't realize they were in possession of what was likely the world's oldest living animal â until they had already killed it.
Natural history. 1  All gerbils have long hind feet and fairly large ears and eyes, but there is variation among other characteristics. Body form varies from stout and compact to slender and gracile. 2  Most gerbils are nocturnal; a few species, however, are active only in early morning and evening or during the day. Gerbils walk and scamper on all four limbs and flee in running leaps when alarmed. Some construct short, simple burrows, but others construct elaborate underground galleries.
Gerbils. Gerbils are generally diurnal animals (active during the day), constructing deep, dark, underground burrows. Gerbils may live for up to 3-4 years, although some may live longer. Take a look at our pet search page to find gerbils up for rehoming. Your duty of care. Gerbils are often kept by young children, because they have a great deal of character. However, their needs are actually very complex and owning one is a big responsibility. If you own or are responsible for gerbils, even on a temporary basis, you are required under the Animal Welfare Act to care for them properly.
