Emeryville witnessed a somber conclusion to its rare aquatic visitor's plight, as a juvenile Minke whale, rarely seen in San Francisco Bay, was humanely euthanized after it became trapped in a mudflat near the Emeryville Marina. The Marine Mammal Center, with a history of only five Minke whale sightings in the area since 2009, confirmed the difficult decision was made in the best interests of the suffering whale. According to an announcement on The Marine Mammal Center's social media, the whale had struggled with peeling white skin akin to a healing sunburn and, despite appearing to be in good body condition, had little chance of survival. A partial necropsy is planned, with results pending a few weeks.
Unfortunately, today the whale became trapped and was unable to be freed from the mudflat. Because this animal was suffering and had little chance of survival, our experts made the difficult decision to humanely euthanize.

The whale's struggle began days earlier with two separate instances of being temporarily stranded in low-tide mudflats. Despite those signs of distress, the creature managed to move to deeper water independently, but the situation deteriorated rapidly yesterday. The Marine Mammal Center spokesperson Giancarlo Rulli revealed to the San Francisco Chronicle that this final stranding brought the whale dangerously close to shore, within 20-25 feet, a notably tighter spot than the over 50 feet in previous incidents. The accumulated stress, illustrated by abnormal breathing patterns, signaled the whale's poor condition, prompting marine specialists to consider their limited options.
First responders, including the Alameda County Fire Department and the East Bay Regional Park District staff, sought to mitigate the whale's suffering by dousing it with water. This measure would prevent its body temperature from rising too high, as the exposed whale had already sustained skin damage likened to sunburn. Despite the compassionate efforts by humans and the arrival of high tide, expected around 11 p.m. yesterday, the whale remained in a precarious situation given the modest one-foot increase in water levels typical for the area.
