Inside The Tanks (Full Documentary)

Marine animal captivity has been a profitable industry, attracting millions globally. However, a darker side has emerged. The film's host, Johnny, travels to Marineland in Antibes, France, home to Europe’s largest marine park with orcas, to investigate the living conditions and practices. He intends to present a balanced view, speaking with both proponents and critics of marine parks.

Johnny meets with the Born Free Foundation, who have been monitoring European marine parks for compliance with EU regulations. They report seeing widespread stereotypical behaviors in captive animals, such as chewing concrete, bobbing, and regurgitating food, which they attribute to boredom due to a lack of environmental stimulation. The foundation suggests ending breeding in captivity and exploring seaside sanctuaries as long-term solutions.

Johnny visits Marineland as a tourist, observing the dolphins and orcas. He notes the seemingly endless circling of dolphins in their pool, feeling it's a 'tease' when the sea is so close. During the orca show, the trainers display an undeniable bond with the animals, and the educational narrative presented makes the experience seem positive. However, after the shows, the animals appear lifeless and bored, suggesting their vitality is largely a performance.

Former Marineland supervisor John Hargrove shares his experiences, revealing an insider's perspective on the negative aspects of captivity. He recalls incidents of aggression from orcas, the trauma suffered by mothers and calves during separation, widespread medication use, and premature deaths. He asserts that orcas in Marineland were routinely drugged and predicts that Marineland will face similar public pressure to SeaWorld, eventually leading to a decline in their orca program.

Dr. Ingrid Visser, a marine biologist, conducts research in the park, documenting abnormal repetitive behaviors (stereotypies) like concrete chewing, head bobbing, and self-mutilation, along with teeth wear. She points out injuries on dolphins, such as wounds from self-mutilation and creases on their necks from unnaturally bending their heads to look above the water. She argues that the tanks offer no natural enrichment, a point she makes evident by contrasting the lack of natural elements in orca pools versus the minimal efforts seen for sea lions. She emphasizes that orcas have a biological need to swim vast distances daily, which is impossible in captivity, leading to severe distress.

John Kershaw, Marineland's zoological director, acknowledges the park is a business driven by visitor revenue. He agrees with some of Dr. Visser's observations about stereotypical behaviors and tank size, attributing them to incompetent staff or bad animal care elsewhere, but not Marineland. He disputes the idea that sea pens are a solution, stating they are still captivity and pose health risks for captive-born animals. Kershaw explains the worn-down teeth of orcas as a result of investigation and play, not self-mutilation, and reveals that drilled teeth are flushed daily due to the impossibility of fillings in a marine environment. He also confirms that Marineland collects sperm for artificial insemination, though breeding is not currently planned, and they are in discussions with SeaWorld about their breeding ban.

Kershaw envisions a future where marine parks transition towards more natural, interactive facilities with advanced designs to attract visitors, moving away from current show-based attractions. The host reflects on his mixed emotions, acknowledging the staff's dedication but expressing concern that animals are exploited for profit. However, he finds hope in the potential for collaboration among organizations, biologists, and parks to create a better future, envisioning a day when these animals are seen in their natural habitats.
