A Ripley’s Aquarium was originally planned in 2004 to be built in Niagara Falls, Ontario[2] next to what is now Great Wolf Lodge around 2007, but plans fell through and Ripley’s eventually relocated to Toronto.[3] Construction began on the attraction in August 2011 with a final cost approaching $130 million.[4] The aquarium opened to the public in October 2013.[4]
The project was a partnership with three levels of government. The federal government’s Canada Lands Company contributed $10 million to the project to develop the “John Street Corridor” linking Front Street with the aquarium, the CN Tower and the Rogers Centre. The Government of Ontario contributed $11 million to the project, and the City of Toronto provided property-tax incentives amounting to between $8 million and $12 million over the first twelve years of the aquarium.[5]
Ripley’s Aquarium has been the target of animal liberation groups such as TARA (Toronto Aquarium Resistance) and MAD (Marineland Animal Defence), which claim animal captivity is synonymous with animal abuse and regularly conduct protests and demonstrations at the facility. Prominent animal conservationist Bob Timmons has also publicly spoken out against Ripley Aquarium’s capture of endangered tiger sharks.
On Oct. 12 multiple videos emerged, showing a man swimming through a shark tank on the main level of the downtown aquarium. Officials at Ripley’s said the man purchased a ticket to enter the aquarium at around 10 p.m. and immediately stripped and hopped over a security barrier to access the shark tank, where he was fully visible to dozens of shocked patrons watching from above the water and from a glass observation area on the level below.
Fish are gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Because in this manner the term “fish” is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology, unless it is used in the cladistic sense, including tetrapods.[1][2] The traditional term pisces (also ichthyes) is considered a typological, but not a phylogenetic classification.
The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods.
Most fish are ectothermic (“cold-blooded”), allowing their body temperatures to vary as ambient temperatures change, though some of the large active swimmers like white shark and tuna can hold a higher core temperature.[3][4]
Fish can communicate in their underwater environments through the use of acoustic communication. Acoustic communication in fish involves the transmission of acoustic signals from one individual of a species to another. The production of sounds as a means of communication among fish is most often used in the context of feeding, aggression or courtship behaviour.[5] The sounds emitted by fish can vary depending on the species and stimulus involved. They can produce either stridulatory sounds by moving components of the skeletal system, or can produce non-stridulatory sounds by manipulating specialized organs such as the swimbladder.[6]
Fish are abundant in most bodies of water. They can be found in nearly all aquatic environments, from high mountain streams (e.g., char and gudgeon) to the abyssal and even hadal depths of the deepest oceans (e.g., gulpers and anglerfish), although no species has yet been documented in the deepest 25% of the ocean. With 33,600 described species, fish exhibit greater species diversity than any other group of vertebrates.
