Meet the Minke Whales

Minke whales are relatively small members of the baleen family, characterised by their streamlined bodies and distinctive, narrow, and pointed rostrums.  These whales are famous for their gentle and curious nature, and they frequently approach boats and divers without posing any threat.

Species Diversity

In the waters of the Great Barrier Reef, you can commonly encounter two primary species within the Minke whale family: the Antarctic Minke Whale (Balaenoptera bonaerensis) and the Dwarf Minke Whale (Balaenoptera acutorostrata).. These whales differ in size, habitat, and migratory patterns.

Seasonal Visitors

Minke whales are known for their seasonal migrations. During the Australian winter months, typically from May to September, these whales journey north to the Great Barrier Reef in search of warmer waters. This annual migration provides a unique opportunity for divers and researchers to encounter these majestic creatures.

Curious Encounters

One of the remarkable aspects is their curiosity towards humans. When approached respectfully and cautiously, they often display playful and inquisitive behaviours, such as breaching, spy-hopping, and swimming close to boats and divers. This makes them a favourite among wildlife enthusiasts and photographers.

Feeding Habits of Minke Whales

Minke whales are filter feeders, primarily consuming small fish and krill by taking in large mouthfuls of water and filtering out their prey through their baleen plates. The nutrient-rich waters of the Great Barrier Reef provide ample food sources for these whales during their visits.

Minke Whale Conservation and Research

Minke whales are classified as a “least concern” species by the International Union for Conservation of Nature (IUCN). However, ongoing research and conservation efforts are essential to monitor their populations and understand their ecological significance within the Great Barrier Reef’s ecosystem.

Whale-Watching Adventures

The Great Barrier Reef offers a range of whale-watching tours and expeditions for those seeking the thrill of encountering minke whales in their natural habitat. These guided experiences provide a safe and educational way to witness the beauty and grace of these gentle giants up close.

Preserving the Wonder

As with all marine life in the Great Barrier Reef, the conservation and protection of minke whales and their habitat are paramount. Efforts to reduce human impact, such as responsible boating and diving practices, are crucial to ensuring the continued well-being of these remarkable creatures and the entire reef

Diet, Behaviour, and Where to See Them in Australia

Minke whales are fascinating marine creatures that can be spotted on the Great Barrier Reef, one of Australia’s natural wonders. These gentle giants are a captivating attraction for visitors exploring the reef’s beauty.

Minke whales, like many marine mammals, have a fascinating reproductive process.

Let’s explore the fascinating topic of minke whale reproduction.

Minke whales, which grace the waters of the Coral Sea off the northeastern coast of Australia, have a remarkable reproductive cycle that adds to the allure of encountering these gentle giants in their natural habitat.

Like many baleen whales, minke whales follow a distinctive reproductive pattern. They are known as seasonal breeders, meaning that they mate and calve during specific times of the year. In the case of the minke whales in the Coral Sea, this typically occurs from June to July when they migrate to these warm, nutrient-rich waters.


During this period, males compete for the attention of female mates. They often display behaviours such as breaching, tail-slapping, and even singing to attract potential partners. Witnessing these majestic creatures court one another is a captivating spectacle.

Once a female chooses a mate, they engage in a ritualised courtship that can include synchronised swimming and vocalisations. Mating takes place, and the female becomes pregnant. The gestation period for minke whales lasts about 10 to 11 months.

Minke whale calves

Around a year later, in the following winter months, females return to the Coral Sea to give birth to their calves. These newborns are already substantial, measuring approximately 7 to 10 feet long and weighing around 1,000 kilogrammes (2,200 pounds). Mother and calf share a strong bond, and the mother provides nourishment and protection to her offspring.

Mothers are known to be attentive and protective, often keeping their calves close by. It’s a heartwarming sight to witness as these young whales learn essential life skills from their mothers in the sheltered waters of the Coral Sea.

Regarding minke whale reproduction, the Coral Sea plays a crucial role as a seasonal destination for these remarkable marine mammals. It offers travellers and wildlife enthusiasts a unique opportunity to witness this captivating cycle of courtship, mating, and calving in a breathtaking natural setting.


They are primarily feeding on small schooling fish, krill, and plankton. They are known for their efficient feeding techniques, often lunge-feeding with their mouths wide open to engulf large quantities of prey.

Normally, they give birth to a single calf with a typical gestation period of about ten months. This special event usually occurs in warmer waters, making it an exciting opportunity for visitors to witness

Interesting Facts

  1. Size Variability: Minke whales come in two primary species: the common minke whale and the Antarctic minke whale. They are among the smallest baleen whales, with lengths ranging from 23 to 33 feet.
  2. Distinctive Coloration: These whales typically have a dark grey to black body colouration on their topside and a lighter shade on their undersides. A white band often encircles their flippers.
  3. Baleen Plates: Minke whales possess baleen plates in their mouths, which they use to filter small prey like krill and small fish from the water.
  4. Solitary or small groups: they are often seen alone or in small groups. They are known for their agility and may be observed breaching or porpoising.
  5. Global Distribution: They are found in oceans worldwide, making them accessible for whale-watching experiences in various regions, including Australia.
  6. Mysterious Vocalisations: They are known for their intriguing vocalisations, including complex “boing” calls. Researchers are still studying these sounds, which are a part of their communication.
  7. Migration Patterns: Some undertake extensive migrations, making them a seasonal highlight in certain areas like the Great Barrier Reef in Australia.
