Scientists have long debated what the purpose of sleep is.
Fish will follow the plankton.
Freshwater jellyfish are growing in abundance in Canadian lakes and rivers. The reasons are complex but climate change is the primary culprit.
Explore the incredible underwater world of plankton.
Box jellyfish have no brains, yet were recently found to be able to learn from touch. Many brainless organisms are now forcing us to rethink what it means to learn.
Jellyfish have a reputation to stinging wild swimmers and huge population “blooms”. But it’s a mistake to dismiss these animals as ocean pests.
UK is home to a diverse range of jellyfish species – encounters with them may become more frequent as the ocean warms.
The Peach Blossom Jellyfish is an invasive species in Canada, and a lack of data is hampering efforts to control populations.
Hot water, cold water, rubbing with sand? What our new review says works best to treat jellyfish stings.
Polylactic acid – a popular bioplastic – does not readily break down when released into the ocean, and could disrupt marine ecosystems
Plankton, some of the smallest organisms on Earth, are leading big changes in the ocean.
The direction a beach faces, relative to wind direction, largely determines how many bluebottles are pushed to shore.
Most jellyfish are “passive” feeders. This means that they float through the water eating whatever they happen to pass in the water and can fit in their mouths.
Scottish holidaymakers are seeing giant jellyfish brought to UK shores by wind and currents
The new underwater robots successfully mimic the sea’s most efficient swimmers.
Transparency is an evolved characteristic of some species to help them survive, even when predators are staring directly at them.
Over the past ten years, scientists have argued about what the earliest animal really was.
Global long-term data simply doesn’t exist for jellyfish, so scientists struggle to predict, track and mitigate their potential effects.
Scientists have identified the world’s smallest animal – for now. It could be possible smaller creatures exist that have not yet been discovered.
