Wild encounter: Minke whales
With an ocean that can feel as vast as space, it’s no surprise that an interaction with a dwarf minke whale can feel as otherworldly as a scene from Star Wars. Clinging to a rope armed with mask and snorkel, your entire body reverberates with a mechanical noise nicknamed the Star Wars sound as an almost fluorescent body glides past you reflecting the sunlight above. While you may not feel like the word dwarf aptly describes the creature that dwarfs you in comparison, these whales – up to 8m long and weighing almost 6 tonnes – are almost 2m smaller than their other minke whale cousins. They are among the smallest baleen whale species.
It wasn’t until the 1980s that scientists recognised the different species of minke, including the dwarf minke subspecies. Through acoustic monitoring, scientists were able to differentiate the sounds of the dwarf whales from the other minke species, further reinforcing their distinct subclassification.
Little is still known about the pocket-sized whale, but the GBR is the only known predictable aggregation in the world and the only place where people are able to swim alongside this majestic creature. It’s believed the population arrive annually between Port Douglas and Lizard Island from subantarctic waters, via migration along Australia’s east coast; however research is still underway to understand their migratory patterns. One thing that is understood is their inherently curious nature, actively seeking out and maintaining long contact with vessels in the water.
A small number of tour boats operate under a special licence that offers divers and snorkellers the rare privilege of interacting with the little whales. Interactions are purely dictated by the minkes, with boat engines cut and set adrift when a pod is spotted. Swimmers entering the water must maintain contact with a rope trailing from the boat and await the inquisitive whales, who seem to enjoy showing off and typically come to investigate.
Mike Ball Minke Whale Dive Expeditions claims a 98 per cent success rate, with the longest encounter lasting 10 hours and the largest pod consisting of 28 whales. If your expedition doesn’t encounter these friendly animals, the Ribbon Reefs are noted as one of tropical north Queensland’s best dive sights so you can explore the other animal and coral life that make the GBR a must-see icon.
Sometimes likened to a dolphin, dwarf minkes are highly manoeuvrable and acrobatic and are known to occasionally breach. If you’re lucky you may witness uncommon behaviours such as a headrise, where the whale rises vertically, exposing its snout above the surface; or the spy-hop, the same move but with its eyes above the surface. Sometimes they will roll and display their bellies, providing an opportunity to determine their sex. Such information is important for ongoing research and divers are encouraged to contribute any photos or observations to the Minke Whale Project. Each dwarf exhibits its own unique colouring and markings as distinctive as a human fingerprint, which allows researchers to follow the behaviours of individual whales.
There’s still a lot to learn about the not-so-little dwarfs, and all who get the privilege of an encounter can contribute to the future understanding of these gentle mammals. Liveaboard expeditions leave from Cairns to the Ribbon Reefs in June and July, typically for three to seven days, with Mike Ball Dive Expeditions, Divers Den or Pro Dive. The expeditions provide a dedicated itinerary for minke whale interactions and offer an exclusive in-water experience unlike any other. While you can scuba dive, most interactions occur with snorkellers, making this once-in-a-lifetime opportunity accessible for all. Imagine the goosebumps moment when a creature about four times your size comes within mere metres of contact – a moment so incredible it will stick with you for life.
