An arms race: Foraging Fish vs. Rorqual Whales

Ever wonder how filter feeding whales are able to capture smaller, fast fish? The authors of this study looked at exactly how the feeding behavior of these whales allows them to catch fast, easily maneuverable foraging fish. Samantha SettaI’m a PhD student in the Rynearson Lab at the University of Rhode Island (URI) Graduate School […]

Using seabirds to study squid

How do scientists track fast swimming squid in the remote and vast open waters of the Southern Ocean? Probably not in any way you’d expect. They use squid predators, specifically a seabird—the wandering albatross—to find the squid for them. These albatrosses are outfitted with some very cool technology to bring the researchers information on their […]

Ocean acidification makes predators dumb

Chemistry is important for a lot of things, but can it change the behavior of animals? Read on to find out how changes in water chemistry alter the behavior of a venomous cone snail! Erin McLeanHi and welcome to oceanbites! I recently finished my master’s degree at URI, focusing on lobsters and how they respond […]

A new king (crab) of the Antarctic

Temperatures are increasing at the poles (and worldwide) and shifting the balance of predator-prey interactions. Predatory king crabs are moving into the Antarctic. How will it change the ecosystem? Sarah GiltzI am a doctoral candidate in Ecology and Evolutionary Biology at Tulane University. My research focuses on the larval dispersal and development of the blue […]

Colorful adaptations: the use of fluorescence as a lure

When viewed under the right filter, the world can look like one big black light party. A large variety of organisms – everything from plants to penguins – are fluorescent. But what is the purpose of glowing when exposed to certain lights? Researchers tested one hypothesis: these fluorescent organisms may be luring in unsuspecting prey. […]
