Norway fjord invaded by monster jellyfish

Norway's Beitstadfjord has been so severely invaded by monster deep sea jellyfish that, just two years since their arrival, they have driven out all of the local fish.

The innermost arm of the Trondheimsfjord now holds an estimated 40,000 tonnes of the helmet jellyfish, only a few years after the fiery red peril first appeared in its waters. 
 
According to Norway's VG newspaper, Jarle Mork, a researcher at NTNU in Trondheim, caught vast quantities of the slimy animal in a single trawl. 
 
"We took up 3.5 tons of monster jellyfish in under ten minutes," he said. "There was a tremendous amount more than we expected. The trawler winch was just about to give way." 
 
Periphylla periphylla usually lives at depths of 1,000 meters but has in recent decades began invading the shallow waters of the fjords. 
 
"The helmet jellyfish is a real beast which has now established itself as the top predator in the inner Trondheimsfjord," he said.

What are the strange transparent ‘jelly bean’ creatures invading Spanish beaches?

Thousands of weird looking gelatinous see-through creatures have been washing up on the beaches on Andalusia.

They might be odd, but they're completely harmless. 

They look a bit like plastic, but these creatures are barrel-shaped planktonic tunicate, known as salps.

Clean up teams have already started to remove them from the shores, but salps present no threat to humans, except for creeping us out!.

These gelatinous blobs, known as las salpas in Spanish and also ‘zapaticos’ , kind of look like jellyfish but without tentacles, but in fact, salps are more closely related to humans than they are jellyfish. 

 

They can reach up 30 centimetres long, but are more commonly washed up the size of a fingernail, they have a primitive backbone, which jellyfish lack.

They are not to be confused with 'sea lice', a term that has been used to describe the larvae of tiny jellyfish that can sting and cause rashes.

Interestingly, it has been suggested that salp could be a secret weapon against climate change, because the algae that they eat uses carbon dioxide from the atmosphere to grow, meaning the salps end up consuming all that carbon.

This said, it is unlikely that salps will be able to keep up with the increased carbon in the atmosphere.

Thousands of these extraordinary creatures can currently be found on the Costa Tropical, the stretch of beaches between Granda province and Málaga, but they are not expected to stick around for long.

Changes in wind direction and sea currents tend to push salp towards the beaches, although salps move by contracting and pumping water through their transparent bodies.
