Shark Tales, in X-ray Magazine's last issue, #63, focused on pain in fish and sharks, and included a short piece on mating behaviour.
Read moreAside from burst swim bladders, fish, like humans, can also get decompression sickness when exposed to rapid changes in pressure during capture.
Read moreDeep-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 moreThe phylogenetic relationship of ctenophores (comb jellies) to other animals has been a source of long-standing debate.
Read moreUsing 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 moreThe 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 moreAlthough they may seem like a strange comparator to humans, zebrafish share a majority of the same genes with humans, making them an important model for understanding how genes work in health and disease.
Read moreThe coelacanth is closely related to the fish lineage that started to move toward a major evolutionary transformation.
Read moreThese 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 o
Read moreNew research by the University of Southampton has revealed corals utilize pink and purple hues as protective sunscreen from damaging sunlight.
Read moreWhat matters is the physical presence of substantial objects on an otherwise featureless seabed.
Read moreDead 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 moreIn the early part of their life cycles, after some days out in the blue as pelagic larvae, anemone fishes settle on the coral reef once they find a suitable host sea anemone.
Read moreBecause 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.
