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 […]

Big Momma: bigger fish are better moms

What makes a fish a good mom? Read here to see why scientists now think that big fish moms are the best fish moms. 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 now an instructor at Georgia Southern University where […]

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 fish with a central focus […]

Top 5 Highlights of Deep Sea Exploration in 2017

What have this year’s deep sea exploration expeditions encountered so far? Read more to find out! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of Akureyri in Iceland, and am currently working at the Smithsonian Institution’s National Museum of Natural History in Ocean Education. I am interested in smart […]

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 […]

Seaweed antioxidants protect fish too

A new study suggests that feeding fish small amounts of antioxidant-rich seaweed can protected them from environmental challenges. 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 […]

Candidate compass genes in fish

A team of American researchers use next-generation sequencing to ask: “magnetoreception, how does it work?” 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 […]

Sea lampreys: grow faster = grow male

A new study suggests that growth rate may determine if lampreys, an invasive fish in the Great Lakes becomes male or female. Read to find out more! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of Akureyri in Iceland, and am currently working at the Smithsonian Institution’s National Museum […]

So cute!

It’s a trap! African penguins impacted by climate change

Young penguins living along the southwestern coast of Africa typically follow cool, nutrient rich water to find food as they grow up. This used to lead them to ‘delicious’ fish such as anchovies and sardines. However, in this ecosystem – the Benguela Upwelling Zone – climate change and overfishing have reduced these fish populations. This […]

Now we got bad blood: Oxygen binding is not affected by haemoglobin subtype in Atlantic cod

Why do northern and southern populations of Atlantic cod have different haemoglobin subtypes? A recent study upsets over 50 years of theory. 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 […]

Grunts and Gnathiids: One Fish’s Daily Migration to Escape Parasites?

Animals move for a number of reasons. The French grunt leaves the coral reefs at night for seagrass. A group of scientists proposes and provides good evidence for why they might do that! Read on to discover whether they’re leaving to avoid being parasitized? Rebecca FlynnI am a graduate of the University of Notre Dame […]

Pet trout: domestication rapidly alters gene expression

The impact of domestication can be detected within one generation in steelhead trout, and may involve adaptation to highly crowded conditions. 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 […]

Rip Rap Sill: The Best of Both Worlds

The hybrid shoreline stabilization method called rip rap sill combines rock structures with native vegetation. This study found that fish biodiversity and abundance in rip rap sills was more similar to a native marsh than a built rip rap. Kari St.LaurentI received a Ph.D. in oceanography in 2014 from the Graduate School of Oceanography (URI) […]

Changing with the environment: how resilient are coral reef fish?

Coral reef fish are some of the most sensitive animals to climate change. How will coral reef fish respond to predicted increases in temperature and carbon dioxide? Do they have the ability to adapt to future conditions or is it already too late? Sean AndersonI am a first year MS candidate at the University of […]

Small fish dine on small plastics and that’s a BIG problem

We’ve heard a lot about plastics in the ocean, but a new study shows the ecological implications of fish eating plastic. Here, researchers found that larval fish are preferentially consuming microplastics and it’s stunting their growth, altering their behavior, and increases death rates. Gordon OberPostdoctoral Researcher, Claremont McKenna College I am currently a postdoc at […]

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 […]

Fish – Animal Parents of the Year, 2016

When we think of parental care, fish aren’t usually the animals that jump to mind. But some fish do take care of their young – some species build and protect nests while others incubate their babies for extended periods of time. Learn all about these caring fish parents! Dina NavonI am a doctoral candidate in […]

You look like your mom: parental effects in Atlantic salmon

In honour of our Mother’s Day theme week, we’ll look at how the environment experienced by parents during reproduction and their early life history influences their offspring. 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 […]

Fooled Ya! How marine animals stay hidden in plain sight

It’s April Fools’ Day! Today’s the day when you try to prank people, convince them your lies are true, and generally make mischief and act sneakily! Animals have to act like it’s April Fools’ Day everyday, and it probably isn’t nearly as much fun since their lives depend on it. Predators sneak up on their […]

Oxygen favours the bold

It takes personality for the African sharptooth catfishes to breathe air. But they also consider their surroundings before visiting the surface. Photo: Wikimedia. Brittney G.
