Catching a ride on plastic: how dangerous bacteria might travel across oceans
Plastic is abundant in the ocean ecosystem. Not only is it harmful to marine animals, but as scientists discovered, it also transports disease-causing bacteria around the ocean. How can the plastic debris in the ocean spread sickness? Diana FontaineI am a PhD student in the Rynearson Lab studying Biological Oceanography at the Graduate School of […]
One Fish, Two Fish, Climate Change, Who Lives?
There is variation within species, and this variation can lead to some individuals surviving better in the face of environmental change. But it is difficult to predict how animals will respond to an environment that is changing faster than they can evolve. Luckily, some scientists found a clever way to study how individuals might respond […]
Hiding at its best: Ultra-black fish of the deep sea
Animals stay hidden from predators using different skin colors and patterns as camouflage. Scientists recently discovered a unique way some fish use ultra-black pigment to hide in the dimly-lit waters of the deep sea. Tejashree ModakCurrently, I am a postdoctoral research fellow in URI. Broadly, I study response of marine species to various stressors such […]

A Deep Water Dimmer Switch: How Fish Use Light as Camouflage
The deep sea can be a dangerous place to be a fish. Certain fish at this depth have been known to create light to help camouflage their silhouettes from predators looking up at them from below, but since they are unable to see their own bellies, how do they know how bright their camouflage should […]
Southern Ocean diatoms: while they’re small, they are mighty!
Tiny organisms called phytoplankton fuel the marine food web. How have they adapted to live in the Southern Ocean where ice cover limits light exposure, water temperatures are frigid, and iron, an important resource for cellular function, is extremely limited? Read on to learn more about these small, but mighty organisms. Diana FontaineI am a […]

East African Lake Fosters a Melting Pot for Cichlid Evolution
Darwin’s famed finches weave a tale of evolution in isolation. Joana Meier and her research team now find that evolution, specifically adaptive radiation, may not actually require such complete isolation to stimulate the creation of new species. Rishya NarayananRishya is a multimedia science communicator with an MS in Media Advocacy from Northeastern University, specializing in […]
The Slow Burn: Slower Metabolisms May Help Mollusks Avoid Extinction
By looking at fossils found in the Western Atlantic, Dr. Luke Strotz and a team of scientists at the University of Kansas and Oxford have come across an intriguing idea: that an animal’s metabolism may be linked to how likely the species is to going extinct. Kristin HuizengaI am a PhD student studying Biological Oceanography […]
Red dead algae
Life on earth has been evolving for a long time – billions of years! The timing of when different kinds of life developed is controversial, but can tell us about the conditions of earth in the past. A group of scientists in Sweden looked at ancient fossils from India, and found what they describe as […]
Now You See Me, Now You Don’t: Using an Invisibility Cloak for Deep-Sea Camouflage
You may not have to go to Hogwarts to find an invisibility cloak of your own. Although, the trip to this extreme environment full of transparent crustaceans may be just as tricky to get to. Read more to find out how hyperiid amphipods are able to make themselves invisible! Ashley MarranzinoI received my Master’s degree […]
Throwing Babies out with the Sea Ice: Ringed Seals Response to Ice Decline
As the Earth warms, sea ice declines. What happens to those animals who rely on the ice? Today’s oceanbites looks at one animal, the ringed seal, and how it may be affected by climate change! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I […]
Like a champion Casanova in the sky
After migrating thousands of miles from their southern wintering grounds, males of a certain species of shorebird log thousands more miles scouring the summer territories for fertile females. It’s pretty nuts. Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.
Clamate Change: How clams may be able to cope with a warming world
Global temperatures are increasing at a rate never before seen in Earth’s history. Although efforts to mitigate this are still very important, it is also important to study and understand what is going to happen to the plants and animals that live here. Evidence of climate change already surrounds us, and the more we know, […]
Ain’t no killing the killifish (for now): on the virtues of genetic diversity
Atlantic killifish are spared extinction in the face of pollution thanks to their remarkable genetic diversity. Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.
Swashbuckling spiders sailed the high seas
Long before the Vikings reached North America, a group of coastal spiders was already sailing around the world using prevailing winds, currents, and rafts. 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 […]
