The oscar (Astronotus ocellatus) is a species of fish from the cichlid family known under a variety of common names, including tiger oscar, velvet cichlid, and marble cichlid. [2] In tropical South America, where the species naturally resides, A. ocellatus specimens are often found for sale as a food fish in the local markets.
Fish that have barbels include the catfish, the carp, the goatfish, the hagfish, the sturgeon, the zebrafish, the black dragonfish and some species of shark such as the sawshark. Barbels house the taste buds of such fish and are used to search for food in murky water. The word barbel comes from Latin barbula 'little beard'. [1]
Colonies growing under overhangs can develop elongations that become shaped like tear-drops, dangle on threads of tissue and eventually detach, landing on the seabed below and growing into new colonies; the sponge has also been observed to develop bubble-like buds on its external surface which become detached and, being buoyant, are dispersed ...
Unlike humans, fish have little or nothing in the way of a tongue, and those that have such an organ do not use it for tasting, but merely for cushioning the mouth and manipulating things within it. The papillae of the fish, and the taste buds found on them, are therefore located on the interior or exterior surfaces of the mouth. [ 2 ]
On "River Monsters," Jeremy Wade traveled to South America to investigate where a Bolivian man named Oscar was killed when face was ripped off while swimming across the South American River.
The lead asserts that Oscars are slow growing for aquarium fish, this is simply not accurate. Oscars grow at a rate approximately 1.5-3cm per month - around an inch - until they reach about about 20cm (8inch). Within the Cichlid family (the family the Oscar is in) there are hardly any varieties that match this rate of growth.

The type II taste bud cells make up about another third of the cells in the taste bud and express G-protein coupled receptors that are associated with chemoreception. They usually express either type 1 or type 2 taste receptors, but one cell might detect different stimuli, such as umami and sweetness. [5]
