The rarest of the 55 Neopet species and the second-to-last to be introduced, Lutaris resemble an otter with a large tail, and were initially introduced to promote the Neopets Mobile service, which would grant users access to their homeland of Lutari Island. However, the service was discontinued in 2009, and the island has been rendered uninhabitable to reflect that, leaving the only ways to get a Lutari to be either to transform an existing pet or to rush to create one during a temporary release once per year on the 19th of April.

Adding to their rarity is that they have an innate fear of captivity. Due to this, they disappear without a trace if a user attempts to abandon one (with the site saying they "ran away"), and as such cannot be adopted from the Pound. Formerly they were not able to be directly transferred onto another account either, though this part of the restriction has since been removed.
