The zebra mussel (Dreissena polymorpha) is a small freshwater mussel, an aquatic bivalve mollusk in the family Dreissenidae.The species originates from the lakes of southern Russia and Ukraine, [3] but has been accidentally introduced to numerous other areas and has become an invasive species in many countries worldwide.
Plant toxins from Phytolacca are being explored as a means to control zebra mussels. [43] [44] The toxic extract of ripe pokeweed berries can be processed to yield a pink dye. [45] [46] [47] Early European settlers to North America would procure a fine red dye from the plant's roots. [48]
Deadliest animals as of 2016 [1]. This is a list of the deadliest animals to humans worldwide, measured by the number of humans killed per year. Different lists have varying criteria and definitions, so lists from different sources disagree and can be contentious.
The Brushy Creek Municipal Utility District said it's no longer worried about an aquatic invader that has taken over dozens of lakes across Texas.
The quagga mussel resembles the zebra mussel, just as its namesake (quagga) resembles the zebra. The quagga mussel shell can be distinguished from the zebra mussel shell because it is paler toward the end of the hinge. It is also slightly larger than the zebra mussel, about 20 mm (0.8 in) wide, roughly about the size of an adult human's thumbnail.
Zebra mussels attach to boats and anything left in the water, including anchors, and can survive for days out of water, often hiding in crevices where they may escape notice.
The "seed" method uses grains of ground shell from freshwater mussels, and overharvesting for this purpose has endangered several freshwater mussel species in the southeastern United States. [18]: 367–403 The pearl industry is so important in some areas, significant sums of money are spent on monitoring the health of farmed molluscs. [99]
The incorporation of the round goby into native foodwebs, coupled with the goby's ability to consume large numbers of invasive mussels (zebra and quagga), may result in greater bioaccumulation of toxins such as PCBs higher in the food chain, since these mussels filter-feed and are known to accumulate persistent contaminants. However, this is ...
