Vicious Killer Shrimp Discovered In UK

Vicious Killer Shrimp Discovered In UK

Most people assume shrimp to be down near the bottom of the marine food chain, but scientists in the UK have discovered an invasive species of predatory shrimp that isn’t afraid to pick a fight with bigger creatures.

According to the British Environment Agency, the shrimp known as Dikerogammarus villosus, has been known to kill its prey and then leave it uneaten.

First spotted by fishermen at the Grafham Water reservoir in Cambridgeshire, the alien species was immediately sent to the Environment Agency for identification.

Invasive species can be plants, animals, and other organisms (e.g., microbes), according to the The National Invasive Species Information Center. In most cases, human actions are the primary means of invasive species introductions, as evidenced by the Asian Carp now invading the Great Lakes region.

One of the most troubling facts is that the shrimp seems to enjoy preying on a range of local species, such as freshwater invertebrates like native shrimp, and even young fish.

This freshwater bully can grow up to 30mm long, making it much larger than native freshwater shrimp (BBC News).

The predatory shrimp originated in the steppe region between the Black Sea and the Caspian Sea, and scientists believe it invaded Western Europe via the Danube.

Wow, what an interesting find, although i agree we should probably not be messing too much with nature :/

The latest alert regarding the "killer shrimps" does not alarm me any wherer near the alarm,panic,fear and total disbelief of the major mistakes mankind has once again caused (but as allways not man enough to tell the truth shame the devil and save the earth)They and the self loving how great i am attitude is causing mother nature to suffer along with her beloved living creatures and the enviroment she has so provided in the way only she the "causer to become" know how.Only last wek i watched tv about the killer hobalt squid that has apparently allso ventured into new waters that up to now have out of bounds due to the low oxygenated waters there. The squid have started hunting as a species not as a natures way was intended and provided. So no living creature is safe in the waters now where ever the squid are as they have the ability to shread anything that is in the waters be it human or marine. The fish have all been eaten and the squid have had an massive increase in thecreation of the offspring they have. Once again know one has had a helping hand in this itsa just happend like the latest killer shrimps.You people are a disgrace to the earth , all its creatures and life forms but much sadder your selves.I reckon the shrimp should now be fished and fed to the squid untill a real solution is found by truth full helpers of this disrespected abused and un appreciated home we should be so very thankfull for the bounties given to us and stop the abusers misusers and such like

Although it sounds like they think these shrimp might have migrated on their own via the Danube, I would not be surprised if a human introduced them. I used to live in Puerto Rico, a land free of snakes that pose any true danger to man. The island does have a small boa constrictor, which might plague a small pet, but is not really much of a problem. Early colonists, however, just had to muck about and change things. Among the many invasive species they imported were mongooses to control the boas. The problem was that mongooses tended to contract rabies and carry it far and wide. To this day, Puerto Rico is still plagued with outbreaks of rabies directly linked to the mongoose population. Yet another paradise, if not lost, significantly damaged. And don't even get me started on the wild boar and goats that they imported.
