Have You Met a Hagfish? It’s About Slime | Deep Look
Рет қаралды 804,465
Жыл бұрынWhat keeps the boneless, jawless hagfish thriving after more than 300 million years? SLIME. The goop it exudes - a mix of mucus and special protein cells- expands to 10,000 times its original volume in less than half a second, potentially clogging the gills of competitors.

DEEP LOOK is a ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small.
---+ What happens when a predator bites into a hagfish?
That predator will get a mouthful of slime! When threatened, the hagfish releases slime from pores that run alongside its body. That slime swells to more than a liter in less than half a second.
---+ Why does a hagfish have loose, baggy skin?
The hagfish's loose skin is a first line of defense. Its vital organs move out of harm's way inside of that baggie onesie, allowing the hagfish time to release slime.

Oh so that's how they don't run out of nutrients producing slime. I was under the impression they produced that much constantly and there nutrient cost for slime was much higher. That makes a lot more sense now.
@mimischiffman626 Жыл бұрын
Producer for the episode here. Same re nutrient cost! But I initially thought they would only be able to slime every so often because they were putting out so much fluid but it really is such a small amount that they excrete compared to the total volume. The ocean water is a huge component of the slimeʻs volume!
@carto4028 Жыл бұрын
Ooh okay so it's the ocean water that supplements most of the cost. Being surrounded by salty water is useful for producing outside substances that are made of mostly water. Useful exploitation of a infinite resource.
