Parasitism
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 […]
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 […]
Sex and parasitism on the open sea and in a fish’s mouth.
Parisites live in fish mouths and undergo opportunistic sex changes. 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 crab in the Gulf of Mexico. When not concerning myself with the plight of tiny crustaceans I can be […]
Sunday brunch: Lox with… lice?
Lox and lice. Not a combination of critters you envision when planning your Sunday brunch. Unfortunately, an increase in drug resistant sea lice is threatening both wild and farmed salmonid populations. Sarah FullerWith academic backgrounds in oceanography, geology, and environmental education, Sarah has traveled to far reaches of the planet to learn everything she can […]
Deadly Dino’s
Copepods dominate the world’s oceans. They are important in the marine food web and help to regulate the global carbon cycle. Being abundant in the ocean is not always fun. Copepods attract attention from infectious parasites, especially from a certain species of dinoflagellate. What potential effects can this parasite have on copepods and what other […]

Here at Oceanbites we love long-term datasets. So much happens in the ocean that sometimes it can be hard to tell if a trend is a part of a natural cycle or actually an anomaly, but as we gather more - by oceanbites 5 months ago
Have you ever seen a lobster molt? Because lobsters have exoskeletons, every time they grow they have to climb out of their old shell, leaving them soft and vulnerable for a few days until their new shell hardens. Young, small - by oceanbites 6 months ago
