Seeing Echoes in the Mind of the Whale

Marshmallow Laser Feast conducted thorough research guided by the wonderful storyteller, filmmaker, and author, Tom Mustill and marine biologist Steffen De Vreese of UPC Bioacoustic Applications Laboratory. We’ve collaborated with marine biologists and bioacousticians to explore and interpret the sensory world of cetaceans. Through a series of interviews and an exhaustive study of available scientific literature, the team gained insights into how these marine species perceive and interact with their environment in ways that go beyond human senses.

The installation is structured around three key species, each serving as a guide through their own chapter.

1-Bottlenose Dolphins: Sculpting with Sound

The first chapter focuses on Bottlenose Dolphins, whose remarkable sensory experience is dominated by echolocation. Unlike humans, these dolphins process acoustic information in their visual cortex, creating a unique sensory fusion where sound becomes a sculpting tool for imagery. Their world is a juxtaposition of sound and sight, where echolocation allows them to “see” through echoes, forming a dynamic, three-dimensional understanding of their surroundings.

Dolphins have colour vision, though it differs from most land mammals. They can perceive shades of grey and are sensitive to near ultraviolet and blue-green light. Genetic studies show that their rods and cones are adapted for underwater environments, allowing them to see with a blue-shifted spectrum compared to terrestrial animals. These adaptations highlight their evolutionary transition from land to sea.

2-Humpback Whales: Depicting memories of the ocean through songs

In the second chapter, Humpback Whales take centre stage, renowned for their hauntingly beautiful songs that echo through the ocean. These complex vocalisations dominate the deep blue, creating an acoustic tapestry that spans vast distances. Their songs, steeped in mystery, form the heartbeat of the ocean’s soundscape.

3- Sperm Whales: Scanning through space and multi-temporality with sound.

The final chapter brings focus to the incredible Sperm Whale, whose vocal abilities surpass any other. Sperm whales can navigate the shadowy depths of the ocean, where sunlight cannot reach, using their powerful vocal clicks to communicate across immense distances. Their echolocation abilities not only guide them through the darkness but also enable communication that can cross entire oceans, connecting them to each other in ways still not fully understood by humans.

Each chapter highlights the profound ways these species experience their environment, using sound as their primary sense to shape their world in ways we are only beginning to grasp.
