Hippopotamus behemoth is an extinct species of hippopotamus from the Early Pleistocene of the Levant. Fossils of it, and its probable ancestor, H. gorgops, are found in the ‘Ubeidiya site in the southern Levant, dating to the Early Pleistocene, around 1.4 million years ago.[1]
H. behemoth differs from H. gorgops in having more elongated feet, and being somewhat smaller.[2] Some experts consider these differences to be too slight to justify separating the two species, however,[3][4] while other authors have considered the species to be closer in morphology to the European species Hippopotamus antiquus.[5]

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.
