European catfish in Southwestern France have learnt how to catch birds by temporarily beaching themselves, a behaviour not seen in their native habitat.
Killer whales (Orcinus orca) are the top marine predator, wherever they are found, and seem to eat everything from schools of small fish to large baleen whales, over twice their own size. The increase in hunting territories available to killer whales in the Arctic due to climate change and melting sea ice could seriously affect the marine ecosystem balance. New research published in BioMed Central’s re-launched open access journal Aquatic Biosystems has combined scientific observations with Canadian Inuit traditional knowledge to determine [...]
Catalan researchers have studied the marine trophic network in Mauritania, on the north west coast of Africa, which is an extremely heavily exploited fishing area, as well as being home to two of the world’s most threatened species of marine mammal – the monk seal and the Atlantic hump-backed dolphin. The results of the study show that industrial and traditional fishing activities along the coast are putting these mammals and local marine ecosystems at great danger.
The killer whale, with its distinctive black-and-white markings, is one of the most familiar marine predators. But great variety lies behind their majestic livery. Andy Foote explains why these differences are so significant. You can download the report HERE.
