10. Mediterranean Jellyfish
One factor that enables species to take hold in new areas is climate change. There is no better example of this than what is happening in the Mediterranean sea. You can deny it all you want people, but sea creatures don’t lie! The waters in the area are now a few degrees warmer than in the past, and this warmth stays around for longer during the year. This has made it the ideal breeding ground for various species of Jellyfish that previously would never have ventured into the cool waters.
Population numbers have been increasing for a while, but they got a massive boost in 2015 when the Suez canal was widened. This gave the jellyfish a quick route into the Mediterranean and their numbers have flourished. The problem with Jellyfish is that they are incredibly difficult to get rid of, and with the ability to lay up to 45,000 eggs in a single day, as well as cloning themselves forever and ever, their presence is on the rise. Authorities are trying to stop them from spreading since their large numbers are affecting tourism and hurting local aquatic animals. The chances of actually eliminating the problem, are thought to be minimal. If you are going for a swim in the mediterranean, watch out for jellyfish!
9. Asian Carp
Asian Carp are a strong lesson about how foreign species can affect an ecosystem. Now, many waterways in the United States are suffering from what was initially a well motivated decision. They were introduced in the South East to clear vast areas of weeds and parasites in order to breathe new life into the rivers, but the surprising and unforeseen consequences have come at a high price.
The four main species of Asian Carp that cause problems- the Bighead, Black, Grass, and Silver- are tough, have few predators, and can lay hundreds of thousands of eggs at a time! They are also able to jump small distances out of the water, which lets them cross dams and barriers. It’s a pretty talented fish, I have to give it that! This jumping ability, along with flooding, have allowed the species to spread up the Mississippi river and further. In the areas they reach they eat all the natural food sources, which cause the native species to die out. Their large numbers are compromising the water quality which makes it less safe to drink and kills the delicate native animals like mussels.
The big concern with Asian Carp is their potential to reach the great lakes where they could wreak havoc, and then spread from there to the rest of the US and Canada and cause even more damage. If that’s possible! Lots of measures are being taken, such as restrictions on people using the fish as bait, underwater electric fences, building new dams, and draining spots with large numbers. Their spread, however, seems inevitable, and despite the best efforts to stop them, the Asian Carp will likely soon be seen in most rivers on the continent.
8. Asian Long Horned Beetle
Another animal from Asia that has made its way over to America and Europe is the Asian Long Horned Beetle. While it may look small and harmless, this creature actually poses one of the greatest threats to our ecosystem because of the way they reproduce.
The females lay their eggs underneath the top layer of bark on a tree, which is not good. As the Larvae emerge, they burrow deeper within the tree, and will consume up to one thousand cubic centimeters of wood during their lifetime. In large numbers these larvae can cause irreparable damage. In the U.S alone, it was estimated in 2015 that the Long Horned Beetle could be responsible for destroying almost a third of urban trees, with a cost of almost 700 billion dollars of losses as a result. Luckily this didn’t happen because there are ways to manage an infestation and the proactive measures taken by authorities have limited their spread. If measures aren’t taken though, you now know that the results could be disastrous (and expensive).
