Dolphins are found in oceans throughout the world, but more often located in deeper waters far out to sea are Rough-toothed Dolphins. Named for the irregular ridges on their teeth, these elegant creatures are celebrated on the Royal Australian Mint’s new Gold Investment and Silver High Relief Proof coins, the fifth in a series featuring different dolphin species.

History & Significance

Most often encountered far beyond land, Rough-toothed Dolphin are less well-known than the familiar Bottlenose Dolphin. Named for the irregular ridges on their teeth which are unique to their species, Rough-toothed Dolphins are superficially similar in appearance to other dolphins, though the differences, such as their conical head and slender nose, are apparent on closer examination. Like other dolphins, they live on a diet of squid and small fish.

These creatures live in groups of up to 20 and exhibit similar behaviors as other dolphins, including occasional bow-riding of boats. Population numbers aren’t known but Rough-toothed Dolphins are not thought to be threatened. However, they can fall victim to nets and hunting by fishermen, as well as to predation by sharks and killer whales.

An elegant Rough-toothed Dolphin is depicted on the Royal Australian Mint’s new Silver High Relief Proof and Gold Investment Coins which show the creature, mouth open to show off its unusual teeth, against a background of the sun on the horizon.
