Moko the dolphin is missing a number of teeth, probably from grabbing and dragging anchor chains on boats, the Department of Conservation (DOC) says.
The friendly dolphin had been living in waters near Whakatane since January, when he moved on from the East Coast.
DOC spokesman James Holborow told NZPAthat Moko was recently checked over and found to have lost eight teeth, possibly from "when he plays with anchor chains or mooring chains or ropes", according to the way the teeth were missing.
DOC was concerned that Moko may develop a secondary infection from the tooth loss.
A team of vets and pathologists were studying photos of Moko's teeth and may pay the dolphin a visit to check his condition.
DOC had appealed to members of the public who had photographed the dolphin while he lived in Gisborne to send them photos.
Moko was not showing any change in behaviour, and would not have difficulty eating, as dolphins did not chew like humans did, Mr Holborow said.
