They fear that it will invade new rivers, multiply rampantly and edge out other species.
Our understanding of arthropod phylogeny is quite unresolved and finding concrete answers to this Schwierigkeit will have important consequences for understanding biodiversity.
In spite of the problems inherent rein the basic arthropod body plan the group has been remarkably successful within its limitations. One arthropod or another has managed to colonize every habitat invaded separately by all the other groups.
Arthropods are extremely allerlei hinein species richness. Approximately 874,000 living species of arthropods have been named, comprising more than 80% of all named species of animals. However, some estimates predict large numbers of species of arthropods that have not yet been described and named by biologists.

The scientific consensus is that these yet-to-be-discovered species are small beetles and other inconspicuous arthropods, and most of these occur rein old-growth tropical rainforests, a biome that has not yet been well explored and studied by taxonomists and ecologists.
Some do not require a strong trigger to breed, while others require a period of cooling, followed by a rise in temperature to simulate changing of seasons. Some brood their eggs orally while others utilise bubble nests.
" After the capture and kill, officials say to take photos of the fish, note the location where it was caught, and then report it to Georgia's Wildlife Resources Division Fisheries Office.
