The dolphin genus Sotalia is considered to have two member species with the classification of Sotalia guianensis[3][4] as a distinct species from Sotalia fluviatilis[5][6] in 2007. This was a result of recent morphometric analyses, as well as mitochondrial DNA analysis.[7]
Members of this genus are found in the Atlantic and Caribbean coasts of Central and South America as well as in the Amazon River and most of its tributaries.[4]
Member species

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
