Pittier's crab-eating rat (Ichthyomys pittieri) is a species of semiaquatic rodent in the family Cricetidae.[2] It is endemic to Venezuela. The natural habitats of this species are rivers and swamps. Its karyotype has 2n = 92 and FNa = 98. This was previously thought to be the highest chromosome number known for a mammal,[3] but it has since been found that the plains viscacha rat or red viscacha rat (Tympanoctomys barrerae) has 4x = 2n = 102.[4]
