Deep-diving fish have a dilemma. With blue and green the only light penetrating their environment, flashy colour patterns are limited to a minimalist palette. A new study has revealed the fishes' solution.Read more
Using a camera-based tracking software system, the researchers compared a control group of rockfish kept in normal seawater to another group in waters with elevated acidity levels matching those projected for the end of the century.Read more
The discovery provides the latest evidence that the oceans, and many of its unexplored regions, represent a vast resource for new materials that could one day treat a variety of diseases and illnesses.Read more
These impulses are transmitted in complex patterns which researchers—after painstaking investigation aided by decoders and software from the intelligence community—have now demonstrated illicit an underlying grammatical structure not unlike that oRead more
New research by the University of Southampton has revealed corals utilize pink and purple hues as protective sunscreen from damaging sunlight.Read more
Dead zones are areas in the ocean where oxygen levels are so low that most fish cannot survive over the long term.
Blue marlins and many other billfish are high-energy fish that need large amounts of dissolved oxygen. By comparing the movement of the blue marlins and the location of low-oxygen areas, scientists have shown that blue marlins venture deeper when dissolved oxygen levels are higher, and remain in shallower surface waters when low dissolved oxygen areas encroach on their habitat from below.Read more
Because of the great variety of these habitats, the senses of these different species have consequently evolved quite differently, exhibiting a great diversity, with many senses not yet understood or even identified. There are thus still many mysteries regarding the behaviour of aquatic creatures. For example, how do eels find their way across the Atlantic ocean? Why is it so very difficult to swim up to a fish from behind without being detected? And even bank-side freshwater fishermen, for example, know that the vibrations from footsteps can be detected by fish.Read more
