Mazes aren’t just for mice: European shore crabs exhibit spatial learning
Mazes aren’t just for mice, although a scientific literature search for maze learning might lead you to think so. In a recent study, scientists investigate crab performance in a complex maze and propose that European shore crabs exhibit spatial learning and memory, potentially tied to their need to find food along the complicated, three-dimensional seafloor.

Gentoo Penguins as Indicators of Climate Change in the Southern Ocean
Carpenter-Kling, T., et al. “Gentoo penguins as sentinels of climate change at the sub-Antarctic Prince Edward Archipelago, Southern Ocean.” Ecological Indicators 101 (2019): 163-172. The newest indicator of climate change is here, and it is penguin puke? While it might seem a little far-fetched, researchers in the Southern Ocean are using the stomach contents of […]
What’s Killing Seabirds in the Bering Sea?
Jones T, Divine LM, Renner H, Knowles S, Lefebvre KA, Burgess HK, et al. (2019) Unusual mortality of Tufted puffins (Fratercula cirrhata) in the eastern Bering Sea. PLoS ONE 14(5): e0216532. https://doi.org/10.1371/journal.pone.0216532 Mass mortality events (or MMEs) are incidents that kill a vast number of individuals in a short period of time. They’re often caused […]
Into the deep: Deep sea mining is upon us, whether you would risk it or not
While we have a lot to discover about the deep sea, we do know that in the depths of the ocean are a number of valuable minerals and metals like gold, manganese, and cobalt. Yet with so little known, companies are ready to dive into the cold deep, gathering these metals for economic gain. Kristin […]
Tracking the Bay’s Rays: Cownose ray migration along the Atlantic coast
If you’ve ever tickled the back of a stingray in an aquarium’s touch tank, you’ve likely introduced yourself to a cownose ray. Despite their popularity in aquaria throughout the U.S., little is known about the movements of these fish in the wild. Grace CasselberryI am currently a Marine Science and Technology Doctoral student at the […]
Threats to Cetaceans: There’s More than Meets the Eye
Researchers spent seven years specifically studying deceased, stranded cetaceans along the coastline of the Canary Islands in Spain to figure out what most likely caused their deaths. They found that while human activity accounted for a large portion, something else was responsible for a much larger percentage of cetacean death. Rishya NarayananRishya is a multimedia […]
Turtle hatchlings attracted to artificial light like moths to a flame
On this Turtle Tuesday, find out how artificial lighting along coastlines due to industrial and commercial development is affecting sea turtle hatchling survival. Nyla HusainI’m a PhD student at the University of Rhode Island Graduate School of Oceanography. I use models to study how small-scale physical processes at the air-sea interface – like waves – impact […]
Lost in the sound: coral planulae habitat selection affected by boat noise
It can be hard to cut through the noises that surround us and focus on the task in front of us, right? This may not just be a human problem. Noise pollution may be another way human activity is negatively affecting corals. Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and […]
Stuck in the middle with you: The trophic ecology of Caribbean reef sharks and large teleost coral reef predators
We often think of sharks as the top of the ocean food web, chowing down on seals and big fish to their heart’s content. That is often not the case! Where does the Caribbean reef shark fall in this hierarchy? Let’s find out. Grace CasselberryI am currently a Marine Science and Technology Doctoral student at […]
Citizen Science and Undersea Stars: The Value of Photographs to Global Megafauna Biology
Check out this article about how tourist pictures of whale sharks are helping scientists learn about whale shark populations around the globe! Matthew LarsenI am a second year master’s student at Coastal Carolina University in the Abel Lab. My interests focus on the ecology and life history of large marine megafauna with a central focus […]
Danger in the deep: uncovering the vertical movement patterns of vulnerable deep-sea sharks
Deep-sea sharks are one of the most poorly studied groups of animals on the planet, yet, their populations are highly threatened by fisheries bycatch. Scientists in The Bahamas develop new field approaches to begin unearthing the vertical movements of a vulnerable deep-sea shark, the Cuban dogfish, and their findings from could help significantly reduce fisheries […]
Coming Home to Roost: A case of parasites relying on ancestral DNA to take advantage of a new penguin host species?
Parasites are nasty and resilient organisms, often highly specialized to fit their hosts. But sometimes, nature allows a bit of wiggle room, opportunity strikes, and new species find themselves vulnerable to these unwelcome houseguests. This could be what has happened to Magellanic penguins. Curious to learn more? Click here! Andrea SchlunkI am a former PhD […]
Melting ice, shifting microbes
Polar bears have been the poster child for sea ice melting in the Arctic. But what does sea ice loss melt mean for the Arctic’s most numerous members – its microbes? Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes […]
Invasive seagrass changes fish community in the US Virgin Islands
Seagrass meadows provide food and habitat for a variety of fish species. Juvenile fish are particularly dependent on the meadows, for the shelter they provide from predators. In the Caribbean, several native seagrasses might be found in the same shallow estuary or coastline, forming a patchwork of meadows that support a variety of different fish […]
A blanket of oil: the role of bacteria in cleaning up after Deepwater Horizon
Nearly one million barrels of oil landed on the seafloor after the Deepwater Horizon spill – a feast if bacteria are able to consume it. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, […]
Riding the phage wave: Emerging role of viruses in the ocean
Viruses live in the ocean, where they infect bacteria who also live in the ocean. Ocean viruses are crucial to the ecosystem, but we don’t know very much about how they ‘survive’ in the ocean. Scientists used data from samples collected all over the world, and explored what types of viruses were in these samples. […]
The answer to starvation? Diversity
Photosynthetic microorganisms can’t go it alone, so they succeed by playing host to a diverse array of microbial partners Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, and what are they doing there? […]
Sea snakes join the dark side to cope with pollution
Black sea snakes are more common in contaminated sites. Why? Brittney G. BorowiecBrittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms and evolution of the respiratory and metabolic responses of Fundulus killifish to intermittent (diurnal) patterns of hypoxia.
The elephant in the oxygen minimum zone
When people think of the animals that inhabit the deep sea, they think of the fascinating, alien-like creatures like the anglerfish or the colossal squid. But, there are other animals that are able to inhabit parts of the deep ocean for a short amount of time, like the elephant seal. Why do they go down […]
The ocean’s tiny, mysterious majority
The earth has more viruses than the universe has stars – but we know far less about our tiny majority at home than we do about the glowing balls of gas in our night sky. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why […]
