The Kollar carp (Cyprinus carpio x Carassius auratus) is a hybrid fish obtained by crossing common carp (Cyprinus carpio) and goldfish (Carassius auratus). Described by the Austrian zoologist Johann Jacob Heckel, its binomial name pays tribute to his compatriot, entomologist Vincenz Kollar. Having been considered a separate species from its original relatives, this fish has as synonym Carpio kollarii (Heckel, 1836). Although this carp is most often found in fish farms, they have also been recorded from the wild.
Diet
[edit]The Kollar Carp has a wide variety of diet options. It includes aquatic plants, insects, and smaller fish. This type of diet makes it an omnivore and a benthic feeder. It does have pharyngeal teeth which are resemble human molars and therefore help with being able to consume smaller fish, and insects.

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.
