phylum
Spinner dolphins were not discovered by a single person, as they have been known to indigenous communities in regions where they are found for centuries. However, in terms of scientific discovery and classification, spinner dolphins were officially identified by scientists in the 19th century.
The seven levels of classification of a dolphin start with the kingdom of Animalia. The phylum is Chordata which means they have a spine. Their class is Mammalia which means they're mammals. The order is Cetacea, the suborder is Odontoceti. There are five families of dolphin - Delphinidae, Iniidae, Lipotidae, Platanistidae, and Pontoporiidae.
if you mean biological classification (as in Homo Sapiens): i have no idea... BUT, the regular name used by vetirinarians and scientists is: Porpoise (poor-puss)
only one species of dolphins at this time that are going extinct are the pink river dolpinsHector's dolphins (New Zealand dolphins) are also in danger of becoming extinct. The endangered river dolphins are Amazon River dolphins, Ganges River dolphins, Chinese White dolphins, Indus River dolphins, and La Plata River dolphins.
Dolphins are vertebrates.
The terms dolphin, porpoise, and whale are confusing and really don't relate to scientific classification. Whales are cetaceans which are neither dolphins (family Delphinae or Platenstoidae) nor porpoises (Family Phocoenidae). Porpoises have spade-like teeth and no beak.
No, but some species of dolphins are endangered, like the Indus River dolphins and the Yangtzee River dolphins. The pink Amazon River dolphins and the Ganges River dolphins are classed as vulnerable.no
they are both dolphins.
