📖 1. Overview

The Indo-Pacific Bottlenose Dolphin lives in shallow coastal waters of the Indian and western Pacific Oceans and has a smaller body and a longer, more slender snout than the Common Bottlenose Dolphin.

🦴 2. Anatomy & Morphology

Compared to the Common Bottlenose Dolphin, its body and head are smaller and its flippers are larger; its back is dark bluish gray and its belly is sometimes pale pink. Its conical teeth number 20–28 on each side of the jaw.

🔍 3. Ecology & Behavior

It mainly eats bony fish and squid, and in shallow water it may kick fish onto the sand with its tail or herd small fish toward shore. It usually travels in groups of 5–15, and females give birth once every 4–6 years.

🇰🇷 4. Connection to Korea

It is listed in the National List of Species of Korea (National Institute of Biological Resources (NIBR)) as "nambang-keundolgorae" (Korean name), and in October 2012 (month 10) the Jeju Indo-Pacific Bottlenose Dolphin was designated as a Marine Organism under Protection under the Enforcement Rule of the Conservation and Management of Marine Ecosystems Act, prohibiting capture for commercial purposes such as shows.
