Key Takeaways

– Sea salps are transparent sea creatures with green horns and slime-covered bodies.
– They possess characteristics of both jellyfish and slugs.
– Sea salps have managed to infiltrate the coast of Washington and Oregon, possibly due to climate change.
– They move by contracting, allowing water to pump through their bodies.
– Sea salps may play a role in removing carbon dioxide from the upper ocean and atmosphere.


Sea salps, the peculiar transparent sea creatures with green horns and slime-covered bodies, have been making waves in the marine biology community. These fascinating organisms possess characteristics of both jellyfish and slugs, making them a subject of great interest and intrigue. In recent years, researchers near the Washington State coast have made surprising discoveries about sea salps and their potential impact on the marine ecosystem. This article delves into the world of sea salps, exploring their unique features, their presence on the West Coast, and their potential role in carbon sequestration.

The Enigmatic Sea Salps

Sea salps, also known as salps, are gelatinous marine animals that belong to the tunicate family. They are transparent, allowing light to pass through their bodies, and possess a distinctive green horn-like structure. These creatures have a tubular body shape and move by contracting, which allows water to pump through their bodies, propelling them forward. This unique mode of locomotion sets them apart from other marine organisms.

The Invasion of the West Coast

While sea salps are typically found in warmer waters, they have recently been observed along the coast of Washington and Oregon, where the waters are significantly colder. This unexpected presence has raised questions among scientists about the factors that have allowed sea salps to infiltrate these regions. One possible explanation is climate change, as rising ocean temperatures may be creating more favorable conditions for sea salps to thrive in previously inhospitable areas.

The Role of Sea Salps in Carbon Sequestration

Researchers are also investigating the potential role of sea salps in carbon sequestration. These organisms feed on phytoplankton, microscopic plants that absorb carbon dioxide from the atmosphere through photosynthesis. As sea salps consume phytoplankton, they produce waste that sinks to the ocean floor, effectively removing carbon dioxide from the upper ocean and atmosphere. This process, known as the biological pump, plays a crucial role in regulating carbon levels and mitigating climate change.

Unraveling the Mysteries

Scientists are actively studying sea salps to unravel the mysteries surrounding these enigmatic creatures. By examining their physiology, behavior, and ecological impact, researchers hope to gain a deeper understanding of their role in the marine ecosystem. Additionally, they are investigating the potential implications of sea salp invasions on native species and the overall biodiversity of the West Coast.

Implications for the Marine Ecosystem

The presence of sea salps along the West Coast could have significant implications for the marine ecosystem. As these organisms consume large quantities of phytoplankton, they may disrupt the food chain and impact the populations of other marine species. Understanding the ecological consequences of sea salp invasions is crucial for maintaining the delicate balance of the marine ecosystem and preserving biodiversity.

Climate Change and Sea Salps

The invasion of sea salps on the West Coast may be a consequence of climate change. As ocean temperatures continue to rise, it is likely that more species will expand their ranges and colonize new areas. Monitoring the spread of sea salps and other marine organisms can provide valuable insights into the effects of climate change on marine ecosystems and help inform conservation efforts.


Sea salps, with their transparent bodies and unique characteristics, continue to captivate the curiosity of marine biologists. Their unexpected presence along the West Coast raises questions about the impact of climate change on marine ecosystems. Furthermore, their potential role in carbon sequestration highlights the intricate connections between different organisms and the environment. As scientists delve deeper into the world of sea salps, they hope to unlock the secrets of these fascinating creatures and gain a better understanding of their ecological significance.
