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
If we ignore the anthropogenic noises such as those made by ships and oil-rigs, and the natural noises made by waves and surf, earthquakes, calving icebergs, etc, there is still a considerable amount of noise, which emanates from the aquatic inverRead more
Research, published this week in the journal Nature Geosciences, pushes back the earliest appearance of photosynthesising organisms from 2.7 to 3.46 billion years ago.Read more
This may seem obvious to most (they had to get to our table somehow), but what may not be apparent is that the relentless pursuit of consumer-friendly fish product is having a massive impact on fish populations around the world.Read more
Researchers describe the bizarre "Swima worms" in Science journal.
The creatures, which the scientists say could be widespread in the deep sea, indicate the extent of biodiversity yet to be discovered in the oceans.Read more
"In nearly 500 million years of vertebrate evolution, and many thousands of vertebrate species living and dead, this is the only one known to have solved the fundamental optical problem faced by all eyes - how to make an image - using a mirror," sRead more
