A photographer sees movement.
Raises the camera.
Focuses.
Presses the shutter.
And hopes.
Only afterward, when reviewing the photographs, does the full scene become clear.
In Blacklow’s case, the camera preserved something that the human eye could barely process in real time.
Twelve dolphins.
One wave.
One brief formation.
Why Dolphins Ride Waves
To people watching from shore, dolphins riding waves can look unmistakably playful.
And sometimes it may indeed be play.
Scientific literature recognizes wave riding as one of the behaviors associated with dolphin play, along with chasing, object manipulation and riding the bow waves created by boats or even large whales.
However, researchers also warn against assuming that every leap, surf or fast-moving behavior is simply dolphins “having fun.”
Dolphin behavior can serve multiple purposes.
In a review published in Current Biology, marine-mammal researcher Vincent Janik noted that wave surfing and leaping may sometimes be energetically efficient ways for dolphins to travel. Behaviors that look playful from a human perspective can also have social, communicative or practical functions.
Bow-riding illustrates the complexity particularly well.
Dolphins are famous for positioning themselves in the pressure waves created near the front of moving ships. Research summarized in the Encyclopedia of Marine Mammals suggests that this behavior may have developed from dolphins’ natural tendency to surf ocean swells and breaking waves. Bow-riding may reduce the effort needed for movement in some circumstances, though researchers have also suggested that dolphins sometimes appear to do it simply as a form of play.
The distinction matters because humans naturally interpret animal behavior through human emotions.
When dolphins leap together, it is tempting to imagine them celebrating.
When they surf, we may picture them enjoying the ocean in the same way human surfers do.
Scientists are more cautious.
An animal cannot explain its motivation to us, so researchers study behavior, context, repetition and social patterns before deciding what function a movement may serve.
Still, dolphins are well documented engaging in behaviors that appear genuinely playful.
Research has recorded object play, social play, aerial movements, unusual swimming patterns and surfing behavior among dolphins. Both younger and mature animals have been observed participating.
So while it would be impossible to say exactly what the twelve dolphins at Manly were “thinking,” their synchronized wave riding fits comfortably within a broader behavioral repertoire scientists have observed in dolphins around the world.
Moving Together Is Part of Dolphin Life
Another reason Blacklow’s photograph feels so remarkable is the coordination.
Humans tend to notice synchronization.
Birds turning together in a flock can look almost choreographed.
Schools of fish seem to move as a single organism.
Dolphins traveling closely together can create the same impression.
Scientific research describes synchronized swimming among dolphins as individuals moving in parallel, often at close distance, with their body orientation and movements closely aligned. Such coordination is associated with social behavior and can be observed in a variety of contexts.
Dolphins are highly social mammals.
Their relationships can involve cooperation, competition, alliances, play and communication.
Researchers studying dolphin societies have documented complex patterns of interaction that extend far beyond simply swimming together.
This does not mean the twelve dolphins in Blacklow’s photograph intentionally formed a symmetrical line for any particular social purpose.
The picture represents only a brief instant.
But dolphins traveling as a group can adjust their movements to one another, and a favorable wave can momentarily make that coordination dramatically visible.
The ocean itself helps create the photograph’s illusion of perfect choreography.
Because the dolphins are all using the same moving body of water, the wave places them within a shared physical structure.
The crest provides a visual line.
The translucent water partially reveals their bodies.
The direction of travel points them the same way.
The shutter freezes everything at precisely the moment when the geometry appears most organized.
A fraction of a second earlier or later might have produced a much less remarkable image.
Manly Beach Was the Perfect Stage
The setting also contributed to the photograph’s impact.
Manly Beach is among the best-known beaches in the Sydney region.
