What’s Hiding at the Most Solitary Place on Earth? The Deep Sea
Kurzgesagt – In a Nutshell・2 minutes read
Less than 2% of Earth's biomass lives in the oceans, with majority located in the top 200 meters where photosynthesis occurs, sustaining a diverse array of marine life. As you move deeper into the ocean, unique adaptations and creatures are found at different depths, showcasing the resilience and survival strategies of deep-sea life.
Insights
- The majority of Earth's biomass is concentrated in the first 200 meters of the ocean, where photosynthesis occurs, highlighting the critical role of this shallow region in sustaining marine life.
- Deep-sea ecosystems, from the twilight zone to the hadal zone, exhibit unique adaptations and species diversity, showcasing the incredible resilience and adaptability of life in extreme environments, such as the vampire squid's feeding method and extremophiles like the snailfish in the Mariana Trench.

What percentage of Earth's biomass is in the oceans?
Less than 2% of Earth's biomass is in the oceans, with the majority concentrated in the first 200 meters where photosynthesis occurs. This highlights the importance of the ocean's surface layers in supporting marine life and ecosystems.
What is the significance of marine snow for deep-sea life?
Marine snow, composed of various materials, plays a crucial role in sustaining deep-sea life such as the giant squid and sperm whales. This organic matter provides essential nutrients for organisms in the deep ocean, contributing to the biodiversity and food chain of these ecosystems.
What unique adaptations are seen in the midnight zone?
The midnight zone, located at 1,000 meters depth, is a dark and energy-efficient environment where unique adaptations like the vampire squid's feeding method are observed. Organisms in this zone have evolved specialized traits to thrive in the low-light conditions and efficiently utilize available resources for survival.
What creatures inhabit the abyssal depths?
The abyssal depths at 3,800 meters are home to slow-moving creatures like the Dumbo octopod and grenadiers fish. These organisms have adapted to conserve energy in the deep-sea environment, showcasing the resilience and diversity of life in the deep ocean.
What extremophiles are found in the hadal zone?
The hadal zone, including the Mariana Trench's Challenger Deep at 11,000 meters, is inhabited by extremophiles like the snailfish. These organisms demonstrate life's ability to thrive in extreme conditions, highlighting the adaptability and survival strategies of deep-sea creatures in the most challenging environments on Earth.
