My Octopus Teacher

Craig Foster turned to the ocean after observing native trackers in the Kalahari who could blend with nature to spot animals. Eighteen years later, at a crossroads in his life, he sought solace and understanding by embracing the challenging cold waters of False Bay near Cape Town, where temperatures dropped to 8-9 degrees Celsius. The frigid water provided a jolt to his senses and helped him reconnect with nature during a difficult period.

The film opens with Foster reflecting on his past experiences with trackers, setting up his later underwater journey.

Foster built trust with the octopus through patient daily presence over 26 days, initially filming her while she hid in algae. The breakthrough came when the octopus reached out a tentacle toward him, marking the beginning of their connection. Over time, she allowed him into her world, revealing how she lived, slept, and hunted in the ocean.

The octopus initially hid in a slippery patch of algae, showing her initial wariness before gradually accepting Foster.

During a fierce encounter with a pajama shark, the octopus lost one of her arms. Foster supported her during the healing process, and by Day 250, she had regained her strength and confidence. The recovery demonstrated the octopus's remarkable resilience and deepened Foster's commitment to her wellbeing.

Pajama sharks were noted to lurk in the same caves as the octopus, presenting a constant threat with their aggressive behavior.

The octopus died naturally on Day 324 after laying a large clutch of eggs, which is the natural end of her life cycle. This event symbolized the cycle of life and death in the ocean, leaving Foster with a profound sense of loss mingled with gratitude for their relationship.

The narrative gradually builds toward this natural conclusion, emphasizing the octopus's journey from youth to maturity.

Foster learned from the octopus's hunting strategies, including her remarkable ingenuity in catching lobsters. She even creatively used Foster as part of her hunting method, demonstrating exceptional intelligence. These shared experiences deepened their bond and transformed Foster's understanding of the kelp forest ecosystem.

By Day 250, the octopus began displaying her hunting ingenuity, which became a key learning experience for Foster.

Foster reflected on wisdom gained from what he described as a mentor-like relationship, learning about life's fragility and humanity's deeper ties to nature. The experience taught him about resilience, connection, and the beauty of interspecies communication, fundamentally changing his perspective on the natural world.

The film establishes early on that Foster was seeking understanding and solace, which the octopus ultimately provided.

The connection Foster developed with the octopus transformed his life and strengthened his bond with his son Tom Foster. The experience helped Tom evolve into a skilled diver and aspiring marine biologist, rejuvenating their father-son relationship through their shared appreciation for marine life.

Foster's journey was fundamentally about reconnection, which extended from nature to his family.

The kelp forest in False Bay near Simon's Town provides a unique underwater environment shaped by the cold Benguela current from the Atlantic Ocean. This hidden ecosystem became the intimate setting where Foster could observe marine life closely, with the kelp forest's complexity enabling the day-by-day relationship building that defines the film.

The opening establishes the kelp forest as a mysterious, challenging environment worth exploring.

Foster embraced water temperatures around 8-9 degrees Celsius as part of his seeking process, viewing the cold as a deliberate challenge that invigorated his senses. After a year of acclimatizing to the icy waters, he began documenting his underwater encounters, which became the foundation for his bond with the octopus.

The film establishes early that Foster was seeking a transformative experience through nature.
