Small species: learning to see what we used to overlook

When diving, we often seek out the grand, the rare and the spectacular.

A turtle. A ray. A moray eel. A grouper. A shark. A school of barracudas. An encounter that will stay with you forever and that you’ll be able to recount once you’re back on the boat.

These encounters are truly special. They’re part of the magic of diving.

But they can also make us forget another kind of richness: that of the small, the unobtrusive, the almost invisible.

Underwater, much of the marine life is not immediately apparent. It hides in crevices, on rocks, in seagrass beds, on sponges, beneath overhangs and at the water’s edge.

  • You can’t just pop in to see it.
  • We need to slow down.
  • We need to learn to look at things differently.

The trap of sensationalism

After a dive, the first question is often:

“So, what did you see?”

And the expected answer often focuses on the most impressive species.

This line of thinking is understandable. It is part of the way we describe the experience. But it can reduce the dive to a list of visible encounters.

We end up looking for what makes an impression, rather than what explains the environment.

The risk is that you might swim through a reef teeming with life and think that “nothing happened”, simply because no large animals appeared.

And yet, life was there.

  • In a hidden prawn.
  • In a tiny nudibranch.
  • In a motionless blenny.
  • In a tube worm that retracts at the slightest movement.
  • In an inhabited sponge.
  • In a seaweed that is home to a whole little world.

Mindful diving often begins when we stop expecting nature to be spectacular.

The reef as a world of detail

A reef is not just a backdrop.

It is a living architecture, made up of shelters, spaces, structures, pathways and interactions.

At first glance, a rock may seem ordinary. But if you stand still for a few minutes, it takes on a different character.

  • A goby appears on the sand.
  • A blenny watches from its burrow.
  • A cleaner shrimp is wiggling its antennae.
  • A nudibranch is slowly moving along its substrate.
  • A little fish is defending its territory.
  • A fixed unit filters the water silently.

The detail then becomes a gateway.

Seeing small things doesn’t mean seeing less. It means accessing another dimension of life.

It means understanding that the ocean is not just about grand encounters. It also exists in micro-habitats, subtle interactions, fleeting behaviours and silent presences.

Slowing down changes your perception

Small species do not reveal themselves to the casual observer.

They take time. Stability. A moment to breathe. A more attentive ear.

As the diver slows down, their perception changes.

He no longer looks only straight ahead. He begins to look around him, down below, into the crevices, across the surfaces, and at the transitions between rock, sand, seaweed and sponges.

His gaze becomes less critical and more curious.

  • He’s no longer just looking for “which animal to see”.
  • He wonders: “What lives here?”

This question changes the whole experience.

A single square metre of reef can be a whole world unto itself. A small crevice can tell a story. A patch of sand can reveal traces, shelters and behaviours.

Slow diving is therefore not just a way of moving slowly. It is a way of revealing what speed renders invisible.

Why small species are important

Small species are not unimportant.

They play a part in maintaining the balance of the environment. Some clean, filter, recycle, provide shelter, feed, camouflage themselves, defend a territory or serve as indicators of local conditions.

They show that biodiversity is not measured solely by the size or rarity of an encounter.

A nudibranch may indicate the presence of its prey. A cleaner shrimp suggests interaction with other fish. A sponge can serve as a substrate or shelter. A blenny may signal a territory. A seagrass bed can harbour a multitude of juvenile or inconspicuous organisms.

Observing small species means learning to understand the ecosystem.

It’s a shift from a recreational dive to a training dive.

Learning to see things differently

Observing small species requires a different approach.

Sometimes you have to choose a confined space, position yourself at a distance, control your buoyancy, limit your movements, and then wait.

At first, you can hardly see anything. Then your eyes adjust.

Shapes become distinct. Textures become clear. Details emerge. A tiny movement catches the eye. An unusual colour stands out. A symmetry, an antenna, a breath, an opening, a trace.

This perspective can be learnt.

It doesn’t necessarily require more knowledge to start with. What it requires, first and foremost, is availability.

Knowledge comes next: through identification, reading, discussion, observation sheets, and the desire to understand what we have seen.

This is precisely one of the reasons Diving Aware exists: to help divers turn their observations into understanding.

Conclusion

Major competitions will always be a key part of the excitement of the sport.

But the experience becomes all the richer when we also learn to notice what isn’t trying to catch our attention.

Small creatures teach us patience, precision and humility. They remind us that life is not limited to what immediately impresses us.

On your next dive, choose a small spot. Stay still. Breathe slowly. Look at the surfaces, the crevices, the details. Let the reef reveal itself before deciding there’s “nothing to see”.

Diving Aware invites you to take a moment to look closely, discover the hidden worlds and respect the fragile richness of marine life.
