Dolphins are highly intelligent marine mammals that live in water but breathe through a blowhole on the top of their head. They are remarkable creatures tha have developed a form on sonar called echolocation to hunt and prey. They are very friendly and playful. Visitors to the waters of the Cocos (Keeling) Islands may be lucky enough to see the three sociable and playful dolphin species that were featured in this lovely stamp issue.
StampNews.com invites our reader to appreciate the original design of these three bright stamps.
The Indo-Pacific Bottlenose Dolphin (Tursiops aduncus) depicted on the first stamp is seen regularly in the inner lagoon, usually in groups. The species is similar in appearance to the Common Bottlenose Dolphin (Tursiops truncatus), but is generally smaller, has a longer beak and develops spotting on the belly as a mature adult.
The Spinner Dolphin (Stenella longirostris), usually seen in small groups, and also in the waters of the inner lagoon, has a very long, thin beak, with a distinctive dark grey back, grey flanks and white belly.
The Common Dolphin (Delphinus delphis) depicted on the three stamp is slender with a long beak that protrudes sharply from its face. This species, easily distinguished from other dolphin species by a unique crisscross colour pattern on the top of its body, is sighted regularly in the deeper waters of the Pulu Keeling National Park lagoon.
