"This is another huge embarrassment to the global reputation of Japan, and another nail in the coffin for the Taiji drive hunts," Lucas said.
Other marine animal advocates are also praising WAZA's recent announcement, a much-welcome public sanction against industries that support the inhumane killings.
Candace Crespi, campaign director for the Oceanic Preservation Society (OPS), called the announcement a "major win for dolphins and those who love them."
"The tide is turning against the exploitation of animals for human entertainment," she said in a statement to The Dodo. "We applaud the WAZA Council for suspending JAZA."
Louie Psihoyos, director of "The Cove" and executive director for OPS, expressed similar sentiments.
"This is one of the best Earth Day presents for those working against the Taiji dolphin slaughter," Psihoyos said in a statement. "You know we're another step closer to shutting down 'The Cove' when the entire world of zoos and aquariums turns its back on the Japanese industry for supporting this heinous and barbarous hunt."
