Whisk-y Business: How Insights from Whisker Anatomy Can Expand Our Knowledge of Seal Behavior (Guest Post by Aubree Jones)

This is a guest post by Aubree Jones. Aubree is working towards her PhD at the University of Rhode Island. She studies how animals use their sensory systems to interact with their environment. She grew up in Oklahoma, where she learned to love the aquatic environment fishing with her dad. It’s no wonder that even […]

Stuck in the mud: a drilling downer for corals

Oil and gas play huge roles in shaping modern lifestyles, providing ease and comfort; while our lives may be simplified, those of larval cold-water corals could be getting cut short—even if their home reef isn’t right next door to a wellhead. Click here to find out about the culprit! Andrea SchlunkI am a former PhD […]

Ocean acidification and baby “squidlife” crises?

Ocean acidification has been known to cause problems for marine mollusks (like oysters and pteropods), because these animals have shells or hard parts that can weaken as acidity increases. There’s another mollusk though with eight arms and two tentacles that may have a larger bag of tricks with which to cope with acidity, but teasing […]

Development of some baby fish may not be harmed by climate change

Climate change is making our oceans warmer and more acidic. These changes are bad for many fish larvae, which may develop incorrectly. But scientists have discovered that development of larval yellowtail kingfish may be unaffected by the changing waters. Anastasia YandulskayaI am a PhD candidate at Northeastern University in Boston. I study regeneration of the […]

Sex Change 101: it Starts in the Brain

With human puberty seemingly beginning earlier and earlier, have you ever wondered what triggered sexual development? Dodd et al., studied just that by examining development in clownfish. Brandy BiggarI am a 2nd year Master’s student at the Memorial University of Newfoundland. I am researching the highly invasive species the European green crab, and the impact […]

Incubation station: are hydrothermal vents speeding up skate-egg development?

Are skates using warm vent water to incubate their eggs? Researchers claim that they have found a direct relationship between temperature and incubation time for skate eggs at hydrothermal vents sites in the Galapagos. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research scientist who has been lucky to have […]

Sharkcano, a melting pot for biology

No, a Sharkcano is not a volcano that erupts sharks. IT IS WAY COOLER THAN THAT! It is a submarine volcano that hosts a diverse macro community in water that is much warmer and more acidic that the surrounding seawater. Read more to find out about this alien-esc ecosystem in the South Pacific Ocean. Anne […]

Do You Have Your Exit Buddy?

It’s a tough ocean out there for a larval fish—sticking together can be the best thing to do. But until now, we didn’t know how beneficial schooling could be. Intrigued? Click here to find out more! Andrea SchlunkI am a former PhD student from the University of Rhode Island, having discovered my love of teaching […]

Killer whale pods: hunting dynamics

Killer whale pods spend almost all of their time together, with the exception of when they hunt. Why are they not social when they hunt? Could it be to ensure the survival of the newest and weakest pod members? Is it related to food availability? It is related to food preference? It is just a […]

Cool Fact! Octopuses spawn with ease when temperatures are lower

Octopuses in the YP may experience temperature changes that do not bode well for reproduction. At what point will the influence of temperature be enough to inhibit the octopus population from growing? Consequences could be tough for octopus fisheries in the area. Read about how temperature stress that a mother experiences can influence her offsprings […]

Parenthood: The Most Rewarding Experience or The Ultimate Sacrifice?

Our human parents make a lot of sacrifices for us! They devote their time and energy, provide for us, invest in us (monetarily, sure, but also emotionally), nurture us, attempt to teach us, make career decisions with us in mind, and lose a lot of sleep worrying about us. However, in the marine world things […]

Why Mom Cares.

Does mom care? If you are a skink from the wrong neighborhood she might, otherwise, you are on your own kid. Read about the evolution of paternal care traits in one skink population that is not observed in the others! Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research scientist […]

Warming up to climate change

Are you a fish that can’t cope with warming oceans? Don’t hesitate, acclimate! Scientists have found if fish have the chance to acclimate to warmer temperatures they may be better off in the future. Gordon OberPostdoctoral Researcher, Claremont McKenna College I am currently a postdoc at Keck Sciences, Claremont McKenna College. I work with Dr. […]

Mercury at elevated levels observed in only some elephant seals, but why?

Mercury: we know it from old-school thermometers and we know if from sushi; and now we know that the distribution in the ocean is reflected in the blood of northern elephant seals. N.B. No elephant seals were harmed during this research. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research […]

The Sting of Sex: odd mating adaptations of box jellyfish

It might be hard for a box jellyfish to buy into the old adage “sex sells,” especially when their gonads are laced with stinging cells. This is just one bizarre adaptation in these organisms, read on to find out more! Gordon OberPostdoctoral Researcher, Claremont McKenna College I am currently a postdoc at Keck Sciences, Claremont […]

What is the source of organic molecules in Von Damm vent fluids?

The origin of life is with out a doubt a fascinating topic of discussion and debate, intensified by the fact that there is no definitive answer (yet). A group of WHOI scientists present a mechanism and environment where organic compounds can be formed from inorganic ones via abiotic production. The plausibility of their suggestion is […]

Sea urchins work harder, faster to cope with ocean acidification

The ability of sea urchins to withstand ocean acidification comes at a hidden cost. Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.

Highlights from the National Shellfisheries Meeting

Ever wanted to know what it’s like to go to a scientific conference? Here’s a summary of what conferences are all about, plus the four most interesting talks I saw at this year’s National Shellfisheries Association meeting. Erin McLeanHi and welcome to oceanbites! I recently finished my master’s degree at URI, focusing on lobsters and […]

A head of their time: how invertebrates had it in them all along to form the vertebrate head

We owe our hard heads to our invertebrate ancestors. Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.
