John Coe and Aquarius do the Rounds

Catching sight of killer whales in the wild is an experience people will never forget; to see a massive black dorsal fin break the surface is truly awe inspiring. Recently, excitement was at a high when west coast celebrities - John Coe and Aquarius - were reported around Mull and Skye, with the pair of old bulls staying in the area for an extended period of time.

John Coe and Aquarius are members of the West Coast Community of killer whales. These individuals form a distinct ecotype and are unique among other north eastern Atlantic populations of killer whale. They can be distinguished from other groups seen off Scottish shores by their unusual sloping eye patch, larger size and distinctive tooth wear.

PHOTO IDENTIFICATION

Individuals whales and dolphins can be recognised by the unique shape of their dorsal fin - like the equivalent of a fingerprint. Killer whales can also be identified by the shape and colouration of their saddle patch – the patch of white behind their dorsal fin. Photo-ID is a tool deployed by researchers, where individuals are identified using photographs and pinned in space and time. This simple technique allows for us to deepen our understanding at both individual and species level - social interactions, individual age, population size, range and habitat preference over time (if any). HWDT has been collating photographs and sightings of the West Coast Community since 1992.

The unmistakable dorsal fin of John Coe

John Coe and Aquarius are the only two members of the West Coast Community that have been reported in recent years, prompting fears that they may be the last remaining members of this population. With John Coe thought to be over 60 years old and Aquarius not that much younger, it’s always a relief to learn that they’re still plying our waters.

WHALE TRACK

Whale Track is an innovative citizen science project where anyone can help monitor whales, dolphins, porpoises and basking sharks in Scottish waters. By letting us know what you’ve spotted, you are directly contributing to the knowledge base and helping protect these awesome creatures. We want to thank everyone who reported their sightings of John Coe and Aquarius through Whale Track - sighting reports are an essential tool to help us track their movements and record behaviours, contributing to our understanding of these unique individuals. We’d also like to thank the wider Whale Track community, a growing group of people who are deepening our understanding of whales, dolphins, porpoises and basking sharks off Scotland’s west coast.

RESPONSIBLE WATCHING

While the potential to spot John Coe or Aquarius is an exciting prospect, it is important to remember how vulnerable they are, despite their large and powerful appearance.

Cetaceans – the collective term for whales, dolphins, and porpoise – are sensitive to disturbance from human activity, including boat traffic, so it is vital we manage our encounters with these animals responsibly. Assessing the situation and behaviour of cetaceans before approaching is vital in understanding and respecting how the encounter will go. Limiting our time with them, keeping our distance, and even avoiding the encounter altogether if they have received a lot of attention already that day, will help minimise any disturbance to the animals, while allowing an enjoyable encounter for all involved.

Watching from land has the least impact on whales and dolphins, creating zero disturbance to their lives. On the west coast of Scotland we have established the Hebridean Whale Trail, providing inspiration for land based watching.

Tomorrow also marks the start of Orca Watch, a Sea Watch Foundation initiative bringing together people on Scotland’s north coast, Orkney and Shetland. Over a 10 day period, citizen scientists will be attending watches hoping to catch sight of the killer whales which frequent those waters. All reports made through Whale Track are validated and passed on to the Seawatch Foundation so if you report a killer whale over the coming 10 days, it will be added to the Orca Watch data.
