I'm loving this discovery! 
I mean, can you imagine a fish having its own personal parasite cleaning service?
It's like the cusk-eels are saying, "Hey, we're good, but our buddy over here has some unwanted visitors – let us take care of it for ya!"
Anyway, it's awesome to see how these creatures are working together in this ecosystem. We can learn a lot from nature and its incredible diversity. The ocean is full of secrets, and scientists like Lisa Levin are helping us uncover them. One thing that got me thinking, though – what if we could replicate some of these natural relationships in our own world? Could we create more symbiotic partnerships to solve real-world problems? Food for thought!
