For the first time ever, scientists have captured incredible footage of a colossal squid (Mesonychoteuthis hamiltoni) in its natural habitat! This monumental achievement, a century after the species was first identified.
First-Ever Footage of Colossal Squid Captured in Its Natural Habitat!
In an incredible achievement for marine scientists, a colossal squid has been filmed in its natural environment for the first time. This monumental event took place a century after the species was first identified. The exciting footage was captured during a 35-day expedition conducted by the Schmidt Ocean Institute near the South Sandwich Islands in March 2025.
The Juvenile Discovery
The footage, captured by a remotely operated vehicle (ROV) named SuBastian, shows a juvenile colossal squid, approximately one foot long. Despite its relatively small size, the video provides astonishing detail. You can see the squid’s iridescent eyes and rust-colored spots, which scientists believe allow it to change its opacity for camouflage. This discovery offers valuable clues about how these creatures survive in the crushing depths of the ocean.
The star of this remarkable footage is a juvenile squid, measuring around 30 cm long and spotted at a depth of 600 meters (approximately 1,968 feet). Experts believe that adult colossal squids can grow to lengths of up to 7 meters (or about 23 feet). It weighs as much as 500 kg, making it the heaviest invertebrate on Earth. This discovery highlights just how little we know about these mysterious ocean creatures.
What’s Unique About Colossal Squids?
The colossal squid, scientifically known as Mesonychoteuthis hamiltoni, remains largely mysterious even to researchers. Beyond its sheer size, the colossal squid possesses other remarkable features. Its tentacles boast rotating hooks, perfect for grabbing prey. Also, it possesses the largest eyes of any known animal, perhaps an adaptation to the dim light of its deep-sea habitat. These remarkable adaptations allow the colossal squid to thrive in an extreme environment.
Until now, most knowledge about this species came from locating remains found in the stomachs of predators like whales and seabirds. Dr. Kat Bolstad, one of the team members verifying the footage, expressed her excitement. Stating, it is humbling to think that they have no idea that humans exist.
Diving Deeper into Marine Life
This unprecedented footage not only showcases colossal squids but also emphasizes the countless discoveries still waiting beneath the ocean waters. During this same expedition, scientists also filmed another unique creature. That is a glacial glass squid, marking another first for marine exploration. Dr. Jyotika Virmani from Schmidt Ocean Institute shared that capturing two new species highlights how much remains unknown about life in our oceans.
The Importance of Marine Research
Marine research plays a vital role in understanding our planet’s biodiversity and ecosystems. As young aspiring scientists and engineers, you can contribute to uncovering these oceanic mysteries. Moreover, by pursuing careers related to marine biology or environmental science. The advancements made during expeditions like these remind us that every exploration opens up new pathways for scientific inquiry.
Be Inspired by Ocean Adventures!
This discovery reminds us how much there is still left to explore in our oceans. The colossal squid’s elusive nature makes it fascinating for researchers and anyone interested in marine biology. Scientists had only learned about these incredible creatures within the last 100 years! With new technology like SuBastian, we can gather more information and better understand their role in our ocean ecosystems.
This inspiring moment serves not just as an educational win. It also reminds us of our responsibility towards understanding and preserving marine life. Every discovery sheds light on how interconnected we are with these magnificent creatures who inhabit our oceans.
