Dolphins are often seen only as cute creatures, but in reality, they are marine mammals with complex social lives, exceptional senses, and intricate vocal communication. Since they are mammals rather than fish, they breathe through lungs, give birth to live young, nurse them, and learn and cooperate within their pods. In the waters of Korea, species such as the Southern Resident Dolphin and Burmeister's Porpoise are marine protected species that require special attention, while globally, the dolphin family includes a wide variety of species such as the Common Dolphin, Atlantic Spotted Dolphin, Pacific White-Sided Dolphin, and Orcas. This list compiles essential knowledge from an ecological and conservation perspective that is beneficial for anyone studying dolphins for the first time.

Indo-Pacific Humpback Dolphin

Southern Resident Dolphin

This is a representative species of wild dolphins that can be observed year-round along the coast of Jeju. Their backs are a dark gray while their underside is a lighter gray. The Jeju population is not large, making it particularly important to treat this marine mammal with care and to respect observation etiquette. When seeking information about dolphins, it's essential to view it from a perspective that respects the habitat and behavior of the wildlife rather than focusing solely on their cute image. If you plan for actual observation or a trip, make sure to check the official guidance, local weather conditions, access restrictions, and social distancing principles before choosing a method that does not disturb the dolphins.

Finless Porpoise

Burmeister's Porpoise

A small marine mammal that can be found along the coast of Korea, it is also known as the 'smiling whale' because of its seemingly smiling face. Its dorsal fin is not very prominent, and its relatively smaller size differentiates it from dolphins. It is vulnerable to bycatch and habitat changes. Similar to dolphins, it's important to view information about this species with respect for its habitat and behavior rather than just their cute appearance. If you plan for actual observation or a trip, ensure to check the official guidance, local weather conditions, access restrictions, and social distancing principles before choosing a non-disruptive method.

Bottlenose Dolphin

Common Dolphin

One of the most well-known dolphin species worldwide. While they are often associated with aquariums, in the wild they exhibit complex social structures, hunting behaviors, and ecological differences by region, making them a crucial species in marine mammal research. Information regarding dolphins should be viewed with an emphasis on respecting the habitat and behavior of the wildlife rather than just their cute image. If planning for actual observation or a trip, please check the official guidance, local weather, access restrictions, and social distancing principles before adopting a non-disruptive approach.

Echolocation

This is the ability of dolphins to use sound and the echoes that return to them to detect prey, obstacles, and their surrounding environment. This is why they can move intricately even in dark waters or murky conditions, and it helps us understand why ship noise and underwater sounds can be stressful for dolphins. Information about dolphins should be viewed with an emphasis on respecting their habitat and behavior rather than just their cute appearance. If you plan for actual observations or trips, ensure to check the official guidance, local weather, access restrictions, and social distancing principles before selecting a non-disruptive way.

Dolphin Social Behavior and Group Living

Social Structure and Pod Life of Dolphins

Dolphins do not live solitary lives; they learn, cooperate, and form relationships within their pods. Activities like hunting for food, caring for their young, traveling, and playing are all interconnected with their social relationships, thus making it more important to observe the group behavior rather than focusing on just one individual. Information about dolphins should be viewed with an emphasis on respecting their habitat and behavior rather than just their cute image. If you plan for actual observation or a trip, please check the official guidance, local weather, access restrictions, and social distancing principles before adopting a non-disruptive approach.

Dolphins and Marine Food Webs

Dolphins are marine predators that feed on fish and squid, and they can serve as indicators of the health of marine ecosystems. A decrease in their food sources or an increase in pollution can both impact dolphin populations, hence it’s important to view them in the context of marine conservation. Information about dolphins should be viewed with an emphasis on respecting their habitat and behavior rather than just their cute image. If you plan for actual observation or trips, please check the official guidance, local weather, access restrictions, and social distancing principles before adopting a non-disruptive approach.

Difference Between Dolphins and Whales

The Difference Between Dolphins and Whales

In everyday language, we often distinguish between dolphins and whales, but biologically, dolphins are included within the whale family. Generally, species that are smaller in size and belong to toothed whales are referred to as dolphins, while some species like the orca are called whales but belong to the dolphin family. Information on dolphins should be viewed with an emphasis on respecting their habitat and behavior rather than just their cute image. If you plan for actual observation or trips, please check the official guidance, local weather, access restrictions, and social distancing principles before opting for a non-disruptive approach.

Dolphins as Marine Protected Species

Species such as the Southern Resident Dolphin and Burmeister's Porpoise are not just simple tourism resources, but marine creatures that require protection. With various threats like capture, bycatch, ship collisions, marine debris, noise, and tourism pressure, conservation should be prioritized over mere observation and utilization. Information regarding dolphins should be viewed with an emphasis on respecting their habitat and behavior rather than just their cute image. If you plan for actual observation or a trip, ensure to check the official guidance, local weather, access restrictions, and social distancing principles before adopting a non-disruptive approach.

To properly understand dolphins, one should look beyond just the phrase ‘intelligent animals’ and consider where they live, what they eat, how they communicate, and what threats they face. Ship noise, bycatch, marine debris, the approach of tour boats, and habitat destruction are all directly linked to the lives of dolphins. Once you have a grasp of the basic ecology, you can observe wild dolphins with a more careful and respectful attitude.
