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
Protogoniomorpha parhassus with black. There are black spots near the margins of both the forewings and hindwings. The underside of the wings has a greenish-white base colour, with eyespots corresponding to those on the upper surface. This species lays tiny eggs similar to those of "Junonia" and "Precis" species. The larvae are similar to those of "Junonia" and "Precis" species, but larger. They feed on "Asystasia" ("A. gangetica"), "Brillantaisia", "Isoglossa" ("I. woodii" and "I. mossambicensis" ), "Mimulopsis", and "Paulowilhelmia" species. The pupae are similar to those of "Junonia" and "Precis" species, but larger. The flight period of the adults is year round,
