Motherhood in the Ocean – An amazing journey

The ocean is a realm of wonder. It’s home to some of the most incredible mothers you’ll ever meet. From creatures with tentacles to those with fins and flippers, their maternal behaviours range from the familiar to the utterly astonishing. Discover the many ways these remarkable creatures care for their young as we delve into the world of oceanic motherhood.

Octopuses – Guardians of the deep: While we might think nine months of pregnancy is long, imagine the dedication of the deep-sea octopus mother, Graneledone boreopacifica. Recorded incubating her eggs for a staggering 53 months, she surpasses all known records for maternal endurance. This commitment, nearly four and a half years in human terms, showcases the unparalleled dedication of these cephalopod mothers.

The black-eyed squid – The sacrifice of love: For the mid-water black-eyed squid, Gonatus onyx, being a mother is the ultimate sacrifice. After laying up to 3,000 eggs in a dark sac, she will cling to them with hooks on her arms as she swims, unable to feed herself. Tragically, the mother squid often sacrifices herself in the process, succumbing to starvation after her eggs have hatched. Her selfless act echoes through the depths of the ocean.

Grey whales – Navigators of the Arctic: A mother grey whale, accompanied by her calf, embarks on an epic migration to the Arctic like a seasoned traveller. She fiercely defends her offspring from predators, including orcas, on the perilous 12,000-mile round-trip journey. The bond between them is an embodiment of the resilience and strength of maternal love in the face of adversity.

Elephant seals – Lessons of independence: While it may take years for human children to become independent, elephant seal mothers prepare their young to be self-sufficient in just a few short weeks. After about 24 days of weaning, the pup, filled with milk and padded with blubber, will venture out on its own. As the mother mates and returns to the sea, her pups learn essential survival skills, exemplifying the rapid transition to independence in the animal kingdom.

Sharks – Masters at parthenogenesis: In a “like mother, like daughter” phenomenon, female sharks have the remarkable ability to clone through parthenogenesis. This asexual reproduction has been documented in species such as the zebra and blacktip sharks. It underlines the adaptability and resilience of these apex predators.

Orcas – Champions of family bond: Family is everything in the world of orcas. Orca mothers, grandmothers and sisters form tight-knit communities living in pods that include multiple generations of matrilineal relatives. Their enduring bonds and shared experiences are a reflection of the importance of family support and unity in the vast expanse of the ocean.

Clownfish – Queen of the reefs:  Mums deserve royal treatment – like a female clownfish. This colourful fish is the “alpha female” of her community. She is the largest fish, surrounded by a harem of smaller males who look after the young and defend her. In a remarkable twist of nature, when she’s gone, the second largest male transforms into a female, ensuring the continuity of their vibrant underwater society.

Mothers play a vital role in shaping the future of their species in the vast and diverse tapestry of marine life. Their resilience, sacrifice and unwavering love testify to the enduring power of maternal instinct in the deep blue sea.
