Moschiola kathygre, a new species of chevrotain, was named in 2005. The small deer can be found in the wet zones of Sri Lanka.

The Australian snubfin dolphin (Orcaella heinsohni), is a species discovered distinct to the closely related Irrawaddy dolphin in 2005. It was the first dolphin species to be named for at least 30 years.

A possible fourth species of peccary, dubbed the giant forest peccary, was discovered in Brazil in 2004. The peccary is said to be larger and behave differently to the three known species. The creature's discoverers claim to have first encountered the animal being killed and eaten by villagers.

In 2003, Japanese scientists announced the discovery of a new species of rorqual, named Omura's whale (Balaenoptera omurai), after extensive studies of Bryde's whale (B. brydei). The scientists also claimed their research settled a long-standing taxonomic argument, and Bryde's whale and the pygmy Bryde's whale (B. edeni) are in fact two distinct species.

Perrin's beaked whale (Mesoplodon perrini) was named as a new species in 2002. It was originally found in 1975 off the coast of California, but misidentified as Hector's beaked whale (Mesoplodon hectori). It is now thought to me more closely related to the pygmy beaked whale (Mesoplodon peruvianus), which was only itself described in 1991.
