Sea World Ancol, also known as Sea World Jakarta or Sea World Indonesia, [1] is a marine aquarium attraction in North Jakarta, Jakarta, Indonesia.It is part of the Ancol Dreamland complex, and consists of a main tank, a shark tank, and various other tanks, including a turtle exhibit.
The orca (Orcinus orca), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus and is recognizable by its black-and-white patterned body. A cosmopolitan species, it is found in diverse marine environments, from Arctic to Antarctic regions to tropical seas.
The remora (/ ˈ r ɛ m ə r ə /), sometimes called suckerfish or sharksucker, is any of a family (Echeneidae) of ray-finned fish in the order Carangiformes. [4] Depending on species, they grow to 30–110 cm (12–43 in) long.
Six species of dolphins have the word "whale" in their name, collectively known as blackfish: the orca, or killer whale, the melon-headed whale, the pygmy killer whale, the false killer whale, and the two species of pilot whales, all of which are classified under the family Delphinidae (oceanic dolphins).

Oceanic dolphins are fast swimmers in comparison to seals who typically cruise at 11–27 km/h (7–17 mph); the orca, in comparison, can travel at speeds of up to 55.5 km/h (34.5 mph). The fusing of the neck vertebrae, while increasing stability when swimming at high speeds, decreases flexibility, which means they are unable to turn their heads.
The genus Orcinus was published by Leopold Fitzinger in 1860, [4] its type species is the orca named by Linnaeus in 1758 as Delphinus orca.Taxonomic arrangements of delphinids published by workers before and after Fitzinger, such as John Edward Gray as Orca in 1846 and Orca (Gladiator) in 1870, are recognized as synonyms of Orcinus.
The IUCN reported in 2008, "The taxonomy of this genus is clearly in need of review, and it is likely that O. orca will be split into a number of different species or at least subspecies over the next few years." [3] However, large variation in the ecological distinctiveness of different orca groups complicate simple differentiation into types. [4]
Wild orca may travel up to 160 kilometres (100 mi) in a day and critics say the animals are too big and intelligent to be suitable for captivity. [130] Captives occasionally act aggressively towards themselves, their tankmates, or humans, which critics say is a result of stress . [ 131 ]
