It appears that some marine mammals are certainly welcoming the presence of offshore wind farms.
Satellite tags on grey and harbor seals reveal that these apex predators are frequenting two offshore wind farms in the North Sea to forage for prey. According to a study recently published in Current Biology, 11 seals showed evidence of foraging at the Alpha Ventus wind farm off Germany and the Sheringham Shoal wind farm off the United Kingdom, moving in a grid-like pattern as they swam from turbine to turbine.
Earlier this month, Spain’s Ministry of Agriculture, Food, and Environment (MAGRAMA) approved a proposal to add four marine areas as Sites of Community Importance to the Natura 2000 Network—the backbone of marine protection in the European Union. These four areas—the western system of submarine canyons in the Gulf of Lions, the Channel of Menorca, the mud volcanoes of the Gulf of Cádiz, and the Bank of Galicia—stemmed from LIFE+ INDEMARES, a project Oceana is a partner on.
- Researchers recently found that the bumphead parrotfish can benefit but also harm coral reef ecosystems in the Pacific. Bumpheads help coral reefs reproduce and reduce-fast growing algae that compete with corals, but since bumpheads do eat coral, they can reduce its abundance and diversity. Red Orbit
When you’re out swimming or surfing at the beach, have you ever wondered which ocean animals surrounding you have teeth? It turns out that sharks aren’t the only marine animals with teeth—a tool in some marine animals may be more widespread than you thought.
From hundreds of sharp, razor-blade-like teeth in great white sharks to the singular long, spiraled tooth on narwhales, teeth come in all shapes in sizes in marine ecosystems. This diversity is for good reason—some use their teeth to shred and slice prey, while others use their teeth more as a harpoon.
It’s that wonderful time of year again on the East Coast: sea turtle hatching season! Turtle nests—from green sea turtles to loggerheads, Kemp’s ridleys, and even more species—are starting to hatch from Virginia to the Gulf of Mexico. If you’re a sea turtle lover and haven’t made it to the beach to catch a nest hatch, don’t worry—the Florida Keys Turtle Cam has got you covered.
Ocean News: Brazil Bans Catfish Fishery to Protect Pink River Dolphins, Arctic Ice Melt Leading to Large Arctic Waves, and More
- In its biggest fisheries ban since 1967, Brazil banned its commercial catfish fishery that uses pink river dolphins as bait. Dolphin populations have severely declined over the past decade, and one population saw a 50 percent drop in numbers since 2004. New Scientist
This lobster species is perhaps best known for its impressive navigational skills. Caribbean spiny lobsters orient themselves with the Earth’s magnetic field, and then follow that point to find food at night and for long migrations. During these migrations, they form queues—long, single file lines in groups of 50 that walk day and night until reaching their destination. Lobsters prefer warmer water, so they migrate en masse to deeper waters when water starts to cool in winter.

Seafood fraud in the Mid-Atlantic region is causing new concern among area watermen and their Congressional representatives. According to crab fishermen in Maryland and Virginia, imported crabmeat is being packaged in the United States, relabeled, and then sold as a “product of the U.S.” This mislabeling—illegal under U.S. law—has gathered attention from the area’s Congressional representatives, who are calling on President Obama to address this seafood fraud.
Ocean News: Climate Change Threatens Red Knots, Pacific Island Leaders Meet to Discuss Ocean Conservation, and More
- Scientists recently found two new coral communities in the Gulf of Mexico show signs of damage from the 2010 BP oil spill. The communities are over 13 miles from the spill, indicating that the spill is “deeper and broader” than thought. Salon
Many marine species face endless obstacles: Overfishing, pollution, and habitat destruction are large threats, as well as climate change and its associated negative impacts. Factors ranging from their habitat, food source, predator defense, migration routes, and breeding grounds are already changing from warming seas, and these impacts are so widespread that it’s caught fisheries managers’ attention.
