Killer algae that eats animals up to 10,000 times its size has been discovered on Denmark’s beaches.

Scientists say they found the microscopic carnivorous creatures, which devour shrimp-like animals up to a millimetre in size, off the coast of Elsinore which is north of Copenhagen.

Copenhagen University’s Terje Berge said: ‘What’s really quite sensational about this discovery is that algae, which appear to be animal and plant at the same time, attack and eat zooplankton.

‘If we imagine an African savannah, this would roughly correspond to the grass suddenly jumping up, attacking and starting to eat the gazelle.’

The study, in the International Society for Microbial Ecology  (ISME) Journal, is the first evidence of carnivorous algae outside Spain.

It was there, in 2006, a species called Karlodinium armiger was observed paralysing and then eating small fish.

Berge added: ‘Researchers took water from the bloom event into the lab and they saw that it paralysed fish two centimetres big.

‘We think that there might be a toxin involved, because the animals get paralysed very fast.’

He said the algae then insert microscopic tubes into the cell walls of their prey, sucking out the nutrients within.

As soon as the nutrients begin to seep out, the algae form a swarm around the attacked animal.

The discovery is of huge academic interest, as algae were previously believed to rely exclusively on photosynthesising sunlight to grow.

He added: ‘Before we have observed that some unicellular animal-like organisms can attack fish. That’s been known for many years.

‘But it’s never been known that these animals with chloroplasts can also take zooplankton.’

The algae are not dangerous to humans.

“The discovery is of huge academic interest, as algae were previously believed to rely exclusively on photosynthesising sunlight to grow.” Actually, it’s been known for quite some time that especially dinoflagellate species can turn carnivorous from time to time (in general, at opportunities or e.g. on certain stages of their life cycle).

Send the algae to the USA. Obama wants to make gasoline from it. Not kidding.

So if the prey are 1mm zooplankton that are 10,000 time bigger than the algae then the algae are only 100nm or (0.1um) in size!!, Someone somewhere is exaggerating the size difference by at least a factor of 100 and it’s not the scientist!

The writer of this article has probably been reading too much Shakepeare. He means Helsingor NOT Elsinore.

Get rid of it then…come along now hurry up

‘The algae are not dangerous to humans.’…….YET! (Just hope they’re not working their way up).

Steve McQueen will have to come along with a CO2 fire extinguisher then. (Or am I getting my films mixed up there?)

Amazing photo, very informative about the process!
