Our world relies heavily on the burning of biological materials such as wood or fossil fuels to harness energy. While we all know that carbon dioxide (CO2) is a harmful byproduct of burning fuel, it’s not the only chemical formed during this process. These chemical byproducts may play a bigger and more complex role in the chemistry of our world than we had previously thought. In this study, researchers traveled the world collecting air and water samples from three different ocean basins to learn more about the unknown chemical consequences of burning fossil fuels on a massive scale.
Microplastics + pharmaceuticals in your pee + increased temperatures = trouble for some fish
Fish are not typically thought of as the most intelligent animals. Yet, new research on manta rays may revolutionize the way we think about how some fish grasp difficult concepts like self-awareness. Read on to see how.
Animals move for a number of reasons. The French grunt leaves the coral reefs at night for seagrass. A group of scientists proposes and provides good evidence for why they might do that! Read on to discover whether they’re leaving to avoid being parasitized?
As any gambler will tell you, the higher the financial risk, the larger the potential reward. As it turns out, the hungrier we get, the higher risks we’re willing to take, and this characteristic transfers over to other members of the animal kingdom. In this study, we look at how cuttlefish make decisions about attacking prey based on their level of hunger and the risk they are willing to accept when the reward is that much sweeter.
If you’re like most people, you’ve probably never ever given any thought to lobsters and their poop. In contrast, the researchers who wrote this study have thought way too much about lobster poop; read on to find out what they discovered!
An ecosystem model predicts how the Puget Sound ecosystem could be affected as the popular geoduck aquaculture industry increases. Including mediating affects, such as changes in predator refuges, allowed ecosystem-wide changes to be uncovered. For example, a decrease in seabirds was predicted due to shifts in prey populations resulting from the anti-predation guards for geoducks.
Mycotoxins in fish feed threaten the health of fish, consumers, and the aquaculture market. The more we learn and understand about these toxins, the more effective regulations can be. Read more to find out how complicated mycotoxin science can be, and how its complexity plays into setting safety standards.
We eat oily fish to get the health benefits of omega-3 fatty acids. However, the level of omega-3s in farmed salmon is changing. How does this stack up to wild-caught salmon? Read more to find out!
The impact of domestication can be detected within one generation in steelhead trout, and may involve adaptation to highly crowded conditions.
Stocks of small ocean-caught fish that are used to make fish feed for aquaculture are at risk of overexploitation. New research shows that farmed tilapia thrive on a diet where 100% of the fish oil in their feed is replaced with microalgae. This is an important step on the road to more sustainable aquaculture practices.

Choosing the right symbiont might be a coral’s ticket to cheating global warming.
We all know dolphins are intelligent creatures that communicate with one another, but a recent study has analyzed dolphin sounds finding evidence of actual human-like, structured conversation. Their chats are full of complex sounds and frequencies, akin to words and sentences. In addition, dolphins appear to have a politeness edge on humans as they were observed to pause and hear out others, rather than interrupting with their own sounds!
We, the Oceanbites writers, want to write for you! Let us know what you’re interested in reading about for a whole month in October! If you have any other suggestions, feel free to share them in the comments below! Thank you!
Using radiocarbon dating, scientists have discovered that the Greenland shark can live longer than any other known vertebrate. How long have some of these individuals been alive?
Compared to the continents, oceanic crust is relatively young, less than 200 million years. But in a corner of the Mediterranean Sea, a remnant of the ancient Neo-Tethys Ocean lurks from the time of Pangaea.
The Southern Ocean has been getting less salty for decades, and scientists have finally proved that sea-ice is responsible for the extra fresh water in the ocean.
Tiny jellyfish live, swim, and eat in a viscous environment. How they capture their food is something of a mystery. A University of Oregon group took advantage of several fancy imaging techniques to shed some light on the matter.
Seagrass habitats worldwide are in decline due to a number of factors. What happens when an invasive species comes on the scene to add to the stressors affecting seagrasses?
