In the best relationships, both parties benefit. And the relationship between the bobtail squid and the bacteria, Vibrio fischeri, has been so good that they’ve evolved together.

Let’s meet this dynamic duo helping each other get the most out of life!

Life’s better when we have someone looking after us. And the symbiotic relationship between the bobtail squid and their bacteria friends does just that! The squid provides a home for the bacteria, while the bacteria glow at night to camouflage their host from below to protect them from predators.

In most cases, the immune system attempts to get rid of foreign bacteria… but somehow, Vibrio fischeri has found a found a supportive home in its squid host. Sarah McAnulty, a Ph.D. candidate at the University of Connecticut is studying how this relationship actually works. And one of our absolute favorite channels, SciFri, brings her research to us. Check it out:

Pretty amazing, right?

One of the many things that nature shows us is how to handle our relationships.

We don’t have enough time to have something in our life that isn’t lighting it up.
