Squalodontidae closely related to the South Asian river dolphin ("Platanista gangetica"). The genus "Squalodon" was named by French naturalist Jean-Pierre Sylvestre de Grateloup in 1840 based on a jaw fragment he thought belonged to a reptile. Fossils discovered later, nevertheless, showed that this was a toothed whale. In extant odontocetes, however, the dentition is atavistic with all teeth reduced to simple, undifferentiated conical shapes. In squalodonts the teeth resemble those of the archaic whales, Archaeoceti, with conical incisors anteriorly and low-crowned, serrated teeth posteriorly. Squalodontidae Squalodontidae or the shark-toothed dolphins is an extinct family of large toothed whales who had long
Asystasia gangetica that use "A. g. micrantha" as a larval foodplant; "Junonia oenone", "Junonia hierta", "Junonia natalica", "Junonia terea", "Protogoniomorpha parhassus", "Hypolimnas misippus" and "Microplexia costimaculalis". The vigorous growth of "A. g. micrantha" in tropical regions makes it a weed which can smother certain indigenous vegetation where it has been introduced. Asystasia gangetica Asystasia gangetica is a species of plant in the Acanthaceae family. It is commonly known as the Chinese violet, coromandel or creeping foxglove. In South Africa this plant may simply be called asystasia. This plant is a spreading herb or groundcover, reaching 600 mm in height or up to
