What appeared to be a rare type of whale that got stuck in shallow waters near the Emeryville Marina Tuesday morning was euthanized after struggling into the afternoon, officials with the Marine Mammal Center said.

A juvenile Minke whale trapped in an Emeryville mudflat was euthanized by The Marine Mammal Center due to poor health.

A juvenile whale spotted swimming in the San Francisco Bay on several occasions in early April was beached on an offshore mudflat Tuesday, according to. A minke whale — possible the same species as the animal reported off Emeryville — and a gray whale were found dead this month in separate incidents along other portions of the California coast.
