Apex Predator & Orca Behaviours
Exploring the dynamic marine environment of Bremer Bay offers unparalleled opportunities to witness the intricate behaviours and interactions of its apex predators, particularly the orcas.
Apex Predator Interactions
In March 2024, an extraordinary event unfolded in the Bremer Canyon when a pod of orcas encountered a sperm whale. This rare interaction provided a unique glimpse into the complex dynamics between these formidable species. The encounter was marked by the sperm whale employing a defensive tactic, releasing a cloud of faeces—a behaviour believed to deter predators. Such events underscore the raw and unpredictable nature of marine life in the Bremer Canyon, offering a vivid reminder of the ongoing battle for survival in the ocean’s depths.
Seasonal Highlights
The Bremer Bay orca season, particularly in February 2024, was marked by a series of remarkable sightings and interactions. Expeditions during this period reported not only frequent orca encounters but also sightings of other marine species, including pilot whales and various seabirds. These observations highlight the rich biodiversity of the region and the dynamic nature of its marine ecosystem. Each tour offered unique experiences, reflecting the ever-changing patterns of wildlife activity in the Bremer Canyon.
Expedition Experiences
Embarking on a killer whale expedition from Bremer Bay is more than just a tour; it’s an immersive journey into the heart of a thriving marine ecosystem. Guests can expect to traverse the stunning landscapes of the Southern Ocean aboard the ‘Alison Maree,’ a 23-meter catamaran designed to handle the local oceanic conditions. The vessel offers three spacious viewing decks and an air-conditioned interior, ensuring comfort throughout the voyage. During the expedition, participants may witness a variety of marine life, from orcas and pilot whales to seabirds like albatrosses and shearwaters. The crew, comprising experienced marine biologists and naturalists, provides insightful commentary, enriching the experience with knowledge about the behaviours and ecology of the observed species. Each day on the water is unique, with the potential for unexpected and thrilling wildlife encounters that leave lasting impressions.
The Power of Predation
In the vast expanse of the Bremer Canyon, the circle of life is vividly on display, showcasing both the raw power of predation and the tender moments of new beginnings.
During an expedition in January 2025, guests aboard the Alison Maree witnessed a significant oil slick upon approaching the hotspot. This slick, a telltale sign of a recent orca predation event, indicated the aftermath of a successful hunt. Such observations provide a rare glimpse into the orcas’ role as apex predators, highlighting their hunting prowess and the dynamic nature of the marine ecosystem in Bremer Bay.

A New Life in the Canyon
In contrast to these powerful displays, the canyon also offers moments of profound tenderness. On January 29, 2025, the crew observed a newborn orca calf accompanying Fanscar’s pod. The calf, with its fresh foetal folds and a floppy dorsal fin, was estimated to be less than a day old. Akama, a member of the pod, was identified as the likely mother, staying in close proximity to her newborn.
This sighting underscores the importance of the Bremer Canyon as a nurturing ground for orca families, offering hope for the continued growth and vitality of the population.
