Tenerife Pilot Whales: Deep Water and Responsible Watching

Many travellers arrive hoping for a swim. Tenerife offers something different, and in a way rarer: the chance to watch a deep-diving, very social animal living its whole year beside a volcanic island. Watching from a licensed boat, at a distance, is the way to do it.

To understand why they stay, we have to look down, not across.

Why do Tenerife pilot whales stay over deep water?

Short-finned pilot whales hunt squid, and also other deep prey like octopus and fish, diving hundreds of metres to find them.

Off southwest Tenerife, the seafloor does not slope gently. It drops steeply into deep water. Research and long-term photo-identification work find more encounters roughly where the depth is between about 800 and 2,000 or 2,100 metres, along these steep slopes, rather than over the shallow shelf near the coast.

So the whales are not here by chance. They live where the underwater landscape gives them food, very close to one of Europe’s busiest island tourism coasts. That tension is the whole story.

A society, not a crowd

Researchers who have followed this population for years describe something quite intimate. Many individuals show strong site fidelity, which means they come back to the same area, and some have been seen again across many years.

There is a mix of longer-term residents and animals that are more transient. Inside a wider, well-organised society, there are stable social clusters. And there is a core area, in the order of tens of square kilometres in the southwest, that matters for resting, socialising, breeding and feeding.

A 2021 study that used boat tracking data to estimate whale watching effort mentions a resident population of roughly 350 to 450 short-finned pilot whales off southwest Tenerife. It also notes that Tenerife carries the large majority of the Canary Islands’ whale watching visitors. Separate work from the University of St Andrews estimated hundreds of residents in southwest Tenerife waters in the late 2000s, with habitat preference peaking at around 1,000 to 1,500 metres depth in its models for the wider Canaries.

These are scientific estimates for specific research periods. They are not a promise of how many animals you will see from a boat on a Tuesday.

The real risk is boats, not whales

Pilot whales do not treat people as prey. For guests who stay on authorised watching boats, the risk from the whales themselves is low. The real ethical problem here is boat crowding and underwater noise, and collision risk is also a real management concern in the Canaries.

The Tenerife to La Gomera marine area has been recognised as a Whale Heritage Area, for its resident pilot whales and bottlenose dolphins and its high diversity of species. The same recognition names the ongoing problem: too many boats, including illegal ones, near the animals. A heritage label does not replace choosing a licensed, patient skipper.

What Spain’s 60 metre rule means on the water

Spain’s national framework for recreational whale and dolphin watching is Real Decreto 1727/2007. It creates a moving protection space around the animals, with a 60 metre exclusion zone at the surface.

If animals come inside those 60 metres, the engine goes to neutral or stops, and the boat does not power up again until they have moved away. The approach should be calm and angled, going with the animals’ direction of travel. Never head on, never from behind, and never cutting across the group. Inside the wider protection space, speed stays low: the decree includes a general limit of about four knots, and never faster than the slowest animal.

As summarised by Spain’s environment ministry, MITECO, this framework also bars recreational swimming, diving and contact with whales and dolphins. So this is a watch-only story, for a good reason. In the Canary Islands, regional rules, including Decreto 178/2000, sit alongside the national decree, and tourist boats are expected to work under the right licences.

What to ask before you step on a boat

You do not need to be an expert. A few calm questions tell you a lot. Is this boat authorised for whale and dolphin watching? How many boats are already with the group, and will you leave if it is crowded? Do you respect the 60 metre zone and slow, parallel approaches? Do you use a hydrophone or explanations to keep the experience quiet, instead of chasing surface action? And what is the plan when there are calves, or when the animals are resting?

A boat that corners a resting group is the one to refuse, even if it is the cheapest.

Patience measured in depth

Bring binoculars and patience. I keep a warm layer for the wind in a small roll-top dry bag, because the waiting is part of the day. If the animals dive for a long time, that is the feeding cycle you came to see. If they travel past without resting, that is still information about how this deep corridor works.

The interesting question is not “how close can I get?” It is “what depth and slope make this home, and how do we stop the boats from erasing it?” Giving these animals deep-water space is how a resident population can keep using the same slopes for decades.

Wildlife encounters are unpredictable. Pilot whale watching should always follow local regulations and experienced professional guidance.

If careful, small encounters like this are how you want to travel, our Ocean Match can help you find the ocean place that fits you.

Questions people ask

Wildlife encounters are never guaranteed and never forced. Ocean Calling works only with vetted, ethical local operators, and every animal is free to approach, or not, entirely on its own terms.
