Dytiscidae
The Dytiscidae – based on the Greek ''dytikos'' (δυτικός), "able to dive" – are the predaceous diving beetles, a family of water beetles. They occur in virtually any freshwater habitat around the world, but a few species live among leaf litter. The adults of most are between long, though much variation is seen between species. The European ''Dytiscus latissimus'' and Brazilian ''Megadytes ducalis'' are the largest, reaching up to and respectively. In contrast, the smallest is likely the Australian ''Limbodessus atypicali'' of subterranean waters, which only is about long. Most are dark brown, blackish, or dark olive in color with golden highlights in some subfamilies. The larvae are commonly known as water tigers due to their voracious appetite. They have short, but sharp mandibles and immediately upon biting, they deliver digestive enzymes into prey to suck their liquefied remains. The family includes more than 4,000 described species in numerous genera. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhantus
''Rhantus'' is a genus of beetle in family Dytiscidae. There are about 100 species distributed worldwide. They often live in pools and marshy habitat types.Alarie, Y., et al. (2009)Larval morphology of ''Rhantus'' Dejean, 1833 (Coleoptera: Dytiscidae: Colymbetinae): descriptions of 22 species and phylogenetic considerations.''Zootaxa'', 2317, 1-102. Several species have colonized oceanic islands and become endemics Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found else ....Hjalmarsson, A.
