multiple classrooms for school groups, including the wet lab education room, which contains both conventional teaching methods such as computers, tables, and chairs, along with live animals and various artifacts. Animals at the aquarium The Vancouver Aquarium currently houses around 300 species of fish, almost 30,000 invertebrates, and 56 species of amphibians and reptiles. They also have around 60 mammals and birds. Currently, the Aquarium no longer houses cetaceans, including Pacific white-sided dolphins. Previous individuals were: Helen, a female Pacific white-sided dolphin, was the last cetacean at the Aquarium. She came to the aquarium from the Enoshima Aquarium in Japan, and is also claimed to have been rescued from entanglement in a fishing net. Helen was part of a multi-year and multi-facility research project focusing on metabolic studies while she was at the Enoshima Aquarium, and is part of a pilot project to understand whale echolocation abilities to prevent whales in the future from becoming entangled in fishing nets. She is distinguishable by the fact that her pectoral flippers are partially amputated due to damage from her entanglement. Helen's tankmate Chester the false killer whale joined her at the Wild Coast on Thursday, June 24, 2015. Since Chester's death on November 24, 2017, Helen was the only cetacean left at Vancouver Aquarium after her tank mate Chester died earlier that same day. Helen was transferred to SeaWorld San Antonio in April 2021 to be in a social group with other Pacific white-sided dolphins, where she died on April 7, 2022, at the approximate age of 36. Laverne came to Vancouver from SeaWorld San Antonio. She died in 2009 due to a twisted intestine. Spinnaker came to Vancouver in 2001 from Japan after getting caught in a fishing net. He died in 2012 due to a prolonged illness. Hana came to Vancouver with Helen in 2005 from the Enoshima Aquarium in Japan after getting caught in a fixed fishing net. She died in 2015 from gastrointestinal torsion and sepsis following a last attempt to save her life with a "breakthrough" surgery. The aquarium used to house a false killer whale: Chester was a young false killer whale that was rescued by the Vancouver Aquarium Marine Mammal Rescue Centre on Chesterman Beach on Vancouver Island in July 2014. In May 2015, Chester was deemed non-releasable by Fisheries and Oceans Canada which based their decision "on the animal’s age at stranding, his lack
