Researchers have identified a new, very toothy fish species that belongs to a newly established genus.
The preserved clingfish specimen had been in the Western Australian Museum for roughly 40 years but when researchers realised its truly amazing mouth features it was pulled for examination.
Given its rarity, the team opted to perform non-invasive computerised tomography, or CT scans, to study the fish through the resulting images and models.
It was soon revealed that the creature's duck-like, wide but flat mouth was filled with an abundance of tiny teeth.
The team estimates the number could be anywhere from 1,800 to 2,300.
They ultimately settled on the name 'duck-billed clingfish'.
