How we found the giant squid - Edith Widder | Summary and Q&A

TL;DR

Scientists use an unobtrusive camera platform with a red light jellyfish lure to finally capture rare footage of giant squid.

Key Insights

• 🎥 Unobtrusive exploration using a camera platform with a red light jellyfish lure leads to the successful capture of six videos of the giant squid.
• 🪼 The red light jellyfish lure mimics a defense mechanism of a common deep-sea jellyfish to attract larger predators and increase chances of survival.
• 🤢 Unobtrusive exploration allows for natural observations and the capture of footage that showcases the behavior of elusive deep-sea creatures.
• 🛟 The successful capture of footage highlights the need for increased investment in ocean exploration and the protection of marine life.
• 🥺 Exploring the ocean can lead to important scientific discoveries, including the identification of bioactive compounds that could benefit humanity.
• 🧑‍🌾 The ocean remains largely unexplored, with only about 5% of it being explored so far.
• 👾 Ocean exploration should receive a similar level of investment and attention as space exploration.

Questions & Answers

Q: What is the approach used to attract giant squid in this expedition?

The scientists used an unobtrusive camera platform called Medusa, which is thrown off the back of the ship and floats passively, attracting the squid with a red light jellyfish lure.

Q: How did the red light jellyfish lure help in attracting the giant squid?

The jellyfish lure imitates the bioluminescent display of a common deep-sea jellyfish, which is a form of defense. When the jellyfish is being attacked, it produces a pinwheel of light to attract larger predators, giving it a chance to escape.

Q: Why is unobtrusive exploration important in capturing footage of elusive animals like the giant squid?

Unobtrusive exploration reduces noise and disturbance, making it less likely to scare away animals. This approach allows researchers to observe natural behaviors and capture footage that would otherwise not be possible.

Q: How does the captured footage of the giant squid provide insights into its behavior?

The footage shows the giant squid behaving in a teasing manner, as well as attacking another object next to the lure. It also reveals the size of the squid, with the potential length of its feeding tentacles being as tall as a two-story house.

Summary & Key Takeaways

• Scientists use an unobtrusive camera platform called Medusa with a red light jellyfish lure to attract giant squid.

• The Medusa is thrown off the back of the ship and floats passively, carried by currents, while the only visible light is the blue light from the lure.

• This approach leads to the successful capture of six videos of the giant squid, marking a breakthrough in ocean exploration.
