This Beautiful House Is Made of Snot

TL;DR

Giant larvaceans build intricate snot mansions that act as filters for food in the ocean, while also helping trap carbon and serving as model organisms for study.

Transcript

Thanks to the Monterey Bay Aquarium and  their research and technology partner MBARI for partnering with us  on this episode of SciShow. They hope that you LARVA this episode! [♪ INTRO] This is a giant larvacean. Sorry, let  me zoom in. THIS is a giant larvacean. The huge structure around it is it’s home —  a palace it built for itself… out of snot... Read More

Key Insights

• 😋 Giant larvaceans build and inhabit intricate snot mansions that serve as effective food filters.
• ❓ Researchers have used advanced technology to visualize and explore the complex chambers and passageways within these structures.
• 😋 The discarded snot mansions become food for deeper-sea creatures and contribute to the global carbon cycle.
• 🛟 Larvaceans serve as model organisms for studying developmental genetics due to their shared characteristics with humans.

Questions & Answers

Q: How do giant larvaceans catch their food?

Giant larvaceans use their mucus mansions as filters to capture small food particles that fall from the ocean's surface. The outer filter catches larger food items, while the inner ones channel ideal-sized food into the larvacean's mouth.

Q: Why do larvaceans abandon their snot mansions?

Larvaceans discard their snot mansions after just a day or less because they become clogged with debris. However, they can quickly create new ones in less than an hour by oozing snot and inflating chambers.

Q: How do larvacean snot mansions contribute to the carbon cycle?

Larvacean snot mansions play a crucial role in the global carbon cycle. As the discarded mansions sink towards the deep ocean, they trap carbon, preventing it from returning to the air. This helps to lower atmospheric carbon dioxide levels.

Q: Why are larvaceans considered model organisms for study?

Larvaceans are part of the chordate group, just like humans, and share many genes and developmental traits. Their fast growth, clear bodies, and genetic similarities make them useful for studying how genes affect development.

Summary & Key Takeaways

• Giant larvaceans are small, tadpole-like creatures that build impressive structures out of mucus.

• These mucus mansions serve as filters to catch food particles that rain down from above.

• Researchers have used lasers and virtual reality to uncover the intricate chambers and passageways within these structures.
