Overfishing threatens the populations of reef sharks that act as the top of the food chain on coral reefs. Their presence keeps the ecosystem in balance and without them, the reefs themselves are at risk of being overtaken by algae and losing much of the diversity they support. But is the story really that simple?
Happy Shark Week! Today we examine a persistent and interesting biogeographical puzzle: why are there so few deep sea sharks?

Over the past few decades, the plight of sharks has been overshadowed by greed for shark fin soup and fears spurred on by movies like Jaws. However, the Bahamas have worked hard to create a safe haven for all shark species through policies and practices. Researchers have recently found that the exciting, cage-free, ecotourism dive spot of Tiger Beach is a very important site for Tiger Shark conservation — Please read on to learn more!
‘Shark Week’ has become a staple of summer television. It is currently the longest continuously running series on television. It is also a rare example of quality scientific research (in any field) getting prime time television coverage. However, scientists and conservationists have highly criticized Shark Week in recent years for ‘fear mongering’ tactics. What does the science say about the impact of Discovery Channel’s Shark Week on the public’s impression of sharks? What can viewers expect from this year’s programming? Find out here.
Cancer is not normally thought of as an infectious disease, but researchers have discovered transmissible cancers in mussels and clams adding to a cadre of examples of contagious cancers.
Scientists (myself included!) have been doing a lot of work on how marine animals respond to rising carbon dioxide (CO2) levels, but CO2 alone isn’t the only problem. This study looks at how having a parasite affects survival in marine snails exposed to high CO2 – do they survive longer in those conditions with or without a bunch of parasites? Read on for a surprising answer!
The darkness can be scary sometimes–but that’s when evolution can get pretty crazy in its adaptations. Meet some of the fishes that can glow in the dark and learn about how many times this special ability evolved–it’s certainly surprised many scientists in the community!
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?
Marine animals living below the surface have to put up with noise generated by human activity. Heavy shipping traffic can bring a lot of noise. How does the common prawn respond?
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.
On this International Webloggers’ Day, we decided to turn our focus to the scientist-writers who make Oceanbites possible. Since I created Oceanbites.org in September 2013, I have been so impressed by the enthusiasm of graduate students all over the world who have contributed to the site. Below, I interview a handful of them about their thoughts […]
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 ability to cope.
Traducido por Sandra Schleier, Artículo Original por Gordon Ober Introducción: Sin ninguna duda los calamares son animales fascinantes y misteriosos. Piénsalo, el calamar gigante, uno de las criaturas más grandes del planeta, es raramente visto vivo. Los calamares son organismos que pueden camuflarse utilizando células pigmentarias llamadas cromatóforos para asimilarse con el fondo del ambiente y […]
I spent a morning learning about the Marine Mammal Center at Moss Landing in California, helped with the intake of a sea lion, and went out on a call with the team.
Oil floats on water, yet oil spills are still devastating for marine life living on the seafloor. How does it get there? A new study shows that it can hitch a ride on sinking particles during an algae bloom, turning marine snow into a “dirty blizzard”. Read on to find out more!
Scientists may have a new option for figuring out how much debris litters our beaches and what it all is! Find out more in today’s World Oceans Day post on marine debris!
We’d love to know what you want to read about for a whole week during the month of July! Take our one question survey to share your opinion! Thank you!
A group of scientists have delved deeper to solve the puzzle of why the ocean around Antarctica has been cooling, while the rest of the ocean is rapidly warming.
