Cetacea
The cetacea are a clade of highly intelligent marine terragen mammals that include three suborders, including the Odontoceti (toothed whales, dolphins, and porpoises), Mysticeti (baleen whales), and Archaeoceti (extinct whales). There were originally about 75 species of whales, dolphins, and porpoises during the Holocene, though this decreased with the extinction of a number of whale species during the Information Age. It is believed that all known species have been lazurogened by GAIA. In addition many species of cetacean have been provolved (the dolphin being one of the earliest creatures to be provolved).
