Farming and animal domestication are trademarks of establishing stable human civilizations. But we are not the only species to develop these methods. Reef-dwelling damselfishes known for farming their own algal gardens have recently been discovered tending to domesticated mysid shrimps. Read more about how and why this domestication developed.

Crushing pressures and freezing temperatures prevent many animals from surviving in the deepest depths of our oceans; yet, somehow, a deep-sea amphipod beats all odds and is able to survive and flourish where few other animals can. Scientists have revealed how these amphipods survive under so much pressure. Ashley MarranzinoI received my Master’s degree from […]
Fishermen and scientists often butt heads when it comes to cod fisheries. But when the two groups work together, they can reveal important insights into cod biology that make regulations more effective for everyone. Learn how fishermen in the Baltic Sea helped scientists study declining cod populations. Ashley MarranzinoI received my Master’s degree from the […]
The noise we make pollutes natural soundscapes and can impede how animals communicate, move, and behave. Researchers now have evidence that man-made noise impacts fish from the very beginning of their life, altering how they develop and grow. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the sensory […]
Destructive fishing practices like bottom trawling damage seafloor habitats. To see how detrimental this fishing technique might be on fragile deep-sea ecosytems, scientists investigated how long it takes seamounts to recover from bottom trawling. The results are not extremely promising. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied […]
Growing sea otter populations are seen as a conservation victory. These cute, charismatic marine mammals are rebounding from near extinction, and saving coastal ecosystems along the way. But their recovery comes with a catch that can cause conflicts with local communities. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I […]
Hagfish might look like disgusting little slime eels, but there is so much more to these jawless fishes. Read on to learn about hagfish and what scientists are uncovering about their slime! Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the sensory biology of deep-sea fishes. I am […]
To properly conserve and manage species, scientists need to understand how they live, grow, and age. But even figuring that out can be difficult when they are large and elusive, like the whale shark. See how scientists can benefit from more tragic moments in our past and use the legacy of nuclear bomb trials to […]
3-D glasses-wearing cuttlefish can show us more than just the latest fashion trends. They can also teach us about evolution and may even help us develop new algorithms for machine learning! Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the sensory biology of deep-sea fishes. I am fascinated […]
Since the first sighting in the 1980s, lionfish have rapidly invaded the waters of the Western Atlantic, the Caribbean, and the Gulf of Mexico. With no natural predators, diseases, or parasites to control the growing population, the adaptable fish has easily expanded its range. However, a newly reported disease may finally be knocking down lionfish […]
The flesh of many pufferfish is laced with a deadly neurotoxin called tetrodotoxin. This toxin successfully wards off pufferfish predators, but tetrodotoxin may also serve a more innocuous purpose: relieving stress. Do not try this at home. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the sensory biology […]
If the adage “you are what you eat” holds true, we may be in some big trouble. A recent study found that pieces of plastics are becoming concentrated in areas where larval fish hunt for food, which could be a big problem for fish and humans alike. Ashley MarranzinoI received my Master’s degree from the […]
Deep-sea anglerfishes are known for their prominent glowing lure extending from their heads. Bacteria are behind the scenes, enabling anglerfish to create their bioluminescence. How and when do anglerfish form the bond with their bioluminescent bacterial partners? Scientists may now have an answer. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island […]
The ocean is a big place and trying to study all of the animals living there can take a lot of time, effort, and some pretty expensive technology. Thankfully, a group of scientists may have found an alternative to the current sampling devices : Sponges. Read more about how scientists are looking into using sponges […]
Marine Protected Areas (MPAs) increase biodiversity and preserve ecosystem health when they are properly managed. But researchers have detected destructive practices that undermine conservation goals still occurring in many MPAs. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the sensory biology of deep-sea fishes. I am fascinated by […]
It may have occurred 8 years ago, but scientists are still talking about the Deep Water Horizon Oil Spill. This epic oil spill made scientists recognize gaps in our knowledge about how oil impacts the environment. To explore the question of how crude oil impacts organisms, a team of scientists at Florida Atlantic University investigate […]
Evolution is riddled with trade-offs. One of the classic examples is how to spread maternal resources – is it better for an individual to have a lot of babies or invest more into only one or two? Researchers examined how this trade-off plays out in the marine world by comparing the competing reproductive strategies of […]
200 feet below the surface of the ocean, light slips away from view. But even here, in the mesophotic zones, life thrives. As scientists learn more about the beautiful fishes and corals that live at these depths we are finding out that they are not immune to human-induced threats. Ashley MarranzinoI received my Master’s degree […]
Coral reefs are extremely important ecosystems. Sadly, climate change, pollution, and various other threats are causing us to lose some of these critical habitats. A group of scientists estimated just how much it will cost us in the future if we lose these important corals. Ashley MarranzinoI received my Master’s degree from the University of […]
Most mammals need to catch their zzz’s to function properly. Fur seals appear to naturally go through prolonged periods of sleep deprivation without suffering obvious side effects. Researchers are studying these semi-aquatic mammals to uncover some mysteries about sleep. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the […]
