TL;DR

Turtles eat plastic because they mistake it for food, especially when the plastic emits a smell similar to their natural food sources.

Key Insights

• 😋 Turtles mistake various types of plastic debris for food, not just plastic bags.
• 😋 Plastic debris that does not visually resemble food can still attract turtles.
• 👃 Turtles respond to the smell of biofouled plastic, indicating that smell plays a significant role in their attraction to plastic.
• 😋 The response to biofouled plastic is similar to the response to the smell of food.
• 🐢 Dimethyl sulfide, a volatile odorant, may be responsible for attracting turtles to plastic debris.
• ❣️ Turtles can become entangled in large mats of plastic debris, highlighting the physical risks posed by plastic pollution.
• 😅 The misconception that turtles eat plastic due to mistaken identity with jellyfish has been debunked.

Questions & Answers

Q: Why do turtles eat plastic?

Turtles eat plastic because they mistake it for food. They were previously thought to confuse plastic bags with jellyfish, but they also ingest other types of plastic debris.

Q: How do turtles respond to the smell of plastic?

A study found that turtles respond to airborne odorants from biofouled plastic. This response is similar to the way they respond to odorants from their food.

Q: What is biofouled plastic?

Biofouling refers to the accumulation of marine organisms on the surface of an object. Biofouled plastic has a layer of organic matter, which may emit odorants that attract turtles.

Q: What odorant might be responsible for turtles' attraction to plastic?

Researchers believe that dimethyl sulfide, a volatile odorant, could be responsible for the turtles' behavior. It is found in biofouled plastic and may mimic the smell of their natural food.

Summary & Key Takeaways

• Turtles were previously believed to mistake plastic bags for jellyfish, but they also ingest plastic debris that has no resemblance to their natural food.

• Turtles can become entangled in large mats of plastic debris that do not visually resemble jellyfish.

• A study found that turtles respond to the smell of biofouled plastic in a similar way they respond to the odor of their food.
