On the floor of the Pacific Ocean, there is almost no movement familiar to the human eye. Here, kelp forests do not sway, sunlight does not penetrate, and food arrives in rare particles slowly descending from the upper layers of the water.
And yet, even in this darkness, life finds a way to rise.
During a study of deep-sea areas southwest of Wake Atoll, the instruments of the expedition vessel Nautilus discovered an unusually tall glass sponge of the genus Caulophacus. It towered above the seafloor at a depth of more than 4 700 meters, and its long stalk was inhabited by many other creatures.
The official observation video was published by Ocean Exploration Trust on 2 September 2026.
A living tower in an oceanic desert
Glass sponges get their name from their internal skeleton, formed by the finest siliceous structures—spicules. They create a strong, openwork framework that allows the animal to maintain its shape under enormous pressure.
Sponges of the genus Caulophacus are especially unusual. Their large, soft body sits atop a long stalk and can resemble a fluffy cloud, cotton candy, or a flower growing in the middle of an abyssal plain.
But this is not a plant. Sponges belong to the oldest multicellular animals on Earth. They pass water through a complex system of canals, extracting bacteria and tiny organic particles from it.
Height helps them rise above the layer of bottom sediments and find themselves in a current of water that brings food. However, it is not only the sponge itself that benefits from this advantage.
In the video recording, researchers noticed animals attached to its stalk or settled near it: sea lilies—crinoids, sea anemones, and other small invertebrates. The exact identity of some organisms has yet to be determined.
In a space that appears almost lifeless, one sponge has become a vertical island.
Why the deep strives upward
On the abyssal plain, suitable hard surfaces are rare. Most of the seafloor is covered with soft sediments, and currents carrying organic particles pass above it.
Therefore, any structure capable of lifting an animal above the ground acquires special value. By settling on the sponge's stalk, small deep-sea inhabitants gain access to a more active flow of water—and with it, to food.
A whole system of interrelations emerges. The sponge filters water, its surface becomes a refuge, the stalk a support, and its internal cavities may serve as a home for tiny organisms. It itself is no longer just a single animal, but the foundation of a small deep-sea community.
This observation is not a report of the discovery of a new species. What we have before us is fresh expedition video documentation that has not yet been formalized into a separate peer-reviewed scientific paper. But it is precisely such encounters that help researchers understand how life is organized in the almost unexplored regions of the ocean.
A world we are only beginning to see
The find was made during the expedition NA181 — Exploration of Wake Island’s Deep Sea, conducted by Ocean Exploration Trust with support from NOAA Ocean Exploration.
Wake Atoll is located between the Hawaiian and Mariana Islands. The surrounding area remains one of the least explored sections of the seafloor under U.S. jurisdiction. According to the expedition organizers, the vast majority of the territory covering more than 407 000 square kilometers is still unmapped and not directly studied.
The vehicles explore abyssal plains and seamounts, film deep-sea animals, collect baseline data on biodiversity, and simultaneously search for maritime heritage objects related to the events of World War II.
Every dive here becomes an encounter not so much with ready answers as with the unknown.
The ocean builds differently
Human cities grow thanks to concrete, metal, and glass. The deep ocean creates its own architecture from living bodies.
Corals become forests. Whale remains become sources of food for decades. Sponges turn into towers around which other creatures gather.
Thus life changes the space around itself. It does not merely adapt to the environment but creates new opportunities for those who happen to be nearby.
In this deep-sea community, there is no architect and no prearranged plan. There is the current, the need to feed, and the ancient ability of organisms to find support in one another.
Perhaps that is why footage of a solitary sponge makes such a strong impression. At first glance, we see a strange creature rising in the darkness. But zoom in with the camera—and a whole world is revealed.
