Steller’s Sea Cow lived in small family groups, with a matriarchal social structure led by the oldest female in the group. They were known for their docile and friendly demeanor towards humans, making them easy targets for hunting. Sadly, due to overhunting by humans in the 18th century, Steller’s Sea Cow became extinct in a short period of time. Their unique lifestyle and behaviors make them a fascinating yet tragic relic of the past.

Stellerʼs Sea Cow Reproduction and Life Cycles

Steller’s Sea Cow, a now-extinct species, had a unique reproduction process and life cycle. These massive marine mammals gave birth to a single calf after a gestation period of around a year. The newborn was independent at birth and relied on its mother’s milk for nutrition.

As the calf grew, it fed on kelp and algae until reaching sexual maturity around 5-7 years of age. Steller’s Sea Cow exhibited a slow growth rate and had a long lifespan, with individuals living up to 20-30 years in the wild.

One significant change during the life cycle of Steller’s Sea Cow was their size, as they could reach lengths of up to 30 feet and weigh several tons as adults. Unfortunately, due to overhunting by humans in the 18th century, Steller’s Sea Cow went extinct within a few decades of its discovery.

Stellerʼs Sea Cow Diet

Steller’s Sea Cow primarily feeds on kelp and other vegetation found in shallow waters. They use their large, flat teeth to strip the kelp off rocks and then swallow it whole. They are herbivores, meaning they only eat plant-based foods. Steller’s Sea Cow is a slow-moving animal, so it feeds on stationary food sources like kelp forests. They require a large amount of kelp each day to sustain their massive size. Some common foods in their diet include various species of kelp, sea grasses, and algae. Their diet is specialized to their environment and they prefer to feed on abundant and easily accessible vegetation.

Stellerʼs Sea Cow Predators and Threats

Steller’s Sea Cow faces threats from natural predators such as orcas and sharks, which prey on both juveniles and adults.
