A small Japanese puffer fish is the creator of one of the most spectacular animal-made structures. To impress the female puffer fish, the male labors 24 hours a day for a week to create a pattern in the sand. If the female finds his work satisfactory, she allows him to fertilize her eggs. She then lays them in the middle of the circle, leaving the male to guard the eggs alone.

When Scientists Get Accidentally Artsy

A new exhibit at the Smithsonian’s National Museum of Natural History lies right at the intersection of art and science, showcasing the inherent beauty of skeletons — that is, fish skeletons.

The Brain Scoop:
Preserving the Migration of Giants: Guyana’s Arapaima

Dr. Lesley de Souza is a conservation scientist here at The Field Museum. Recently she’s been working in Guyana alongside the local people with the goal of creating a protected area.

One animal in particular, the arapaima, is a massive and threatened fish that uses flooded forests for breeding- but there was little known about where they go, and how they use these waterways in the rainy season. So, she decided to track them by inserting radio transmitters into the fish - and today, she and her collaborators are one step closer to establishing a natural preserve in the country.

Why Should I Care For the Oceans?

We’ve all heard it:

“Why does it matter if we overfish tuna? It tastes so good!”

“If the oceans dried up tomorrow, why would I care? I live 500miles away from any body of water!”

The thing is, without the oceans, we would all be dead. Our planet would probably look like Mars. There would be no freshwater, no food for us to eat, no suitable climate for us to survive.

Whether you live by the coast, or only see the ocean once a year on holiday, the ocean has an impact on your life. Every breath you take, every food or drinks you have… is thanks to our oceans. Every single individual and living being on this planet is deeply connected, and extremely dependent upon our seas.

The oceans regulates climate, weather, and temperature. They act as carbon dioxide ‘sinks’ from the atmosphere. They hold 97% of the Earth’s water. They govern our Earth’s chemistry; all the microbes and microscopic organisms at the very bottom of the food chain support our own existence. The oceans are also crucial for our economies, health and security.

The past generations have been raised with the idea that the ocean is huge (and it is) and resilient, and that we could basically take from or put into the oceans as much as we wanted. Now, we found out that we cant go on this way. This mentality is part of our problem and it needs to change.

While we have made tremendous discoveries about the oceans over the last few decades, we have also caused more destruction to the sea than ever before. Many fisheries stocks are overfished, catastrophic fishing techniques are destroying the habitats and depleting populations, many marine species are on the verge of extinction, coral reefs are dying, pollution run-offs from agricultural farms are creating dead-zones where nothing can grow or live, millions of gallons of oil have devastated the Gulf of Mexico, bigger and faster container ships create noise pollution for marine mammals and endangers them…The list goes on, and on. We have had so much impact that we have actually changed the pH of the oceans! 

Pretty overwhelming, uh? 

So yes, you should care, because if the oceans crash, we as a species are crashing with them. The entire planet Earth will be gone. And if that’s not enough of a wake-up call for you, I don’t know what else could be!

While all the current marine conservation issues appear huge and insurmountable, there is still hope. Each individual can make a difference now. YOU can make better choices about which fish to consume (or not at all!) and ask about the way they were caught or raised, YOU can encourage sustainable fishing practices, YOU can decide not to use fertilizer or pesticides in your backyard, YOU can bring your own reusable bag to the grocery store and stop using plastics, YOU can stop using products with microbeads, YOU can participate in beach clean-ups, YOU can start your own research and discover even more awesome things about the oceans… YOU can spread the word to your skeptic friends! Have people follow in your footsteps; inspire your friends and family. Be the change :) !
