What is the maximal age a Rough-toothed dolphin reaches?
An adult Rough-toothed dolphin (Steno bredanensis) usually gets as old as 32 years.
When born, they weight 11.3 kg (24.91 lbs) and measure 99.3 cm (3′ 4″). They are a member of the Delphinidae family (genus: Steno). Fully grown, they reach a bodylength of 2.44 meter (8′ 1″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
The rough-toothed dolphin (Steno bredanensis) is a species of dolphin that can be found in deep warm and tropical waters around the world.The species was first described by Georges Cuvier in 1823. The genus name Steno, of which this species is the only member, comes from the Greek for ‘narrow’, referring to the animal’s beak — which is a diagnostic characteristic of the species. The specific name honours van Breda, who studied Cuvier’s writings. There are no recognised subspecies.
