About Marine Mammal Rescue Day

Marine Mammal Rescue Day has been used in California government recognition connected with marine-mammal rescue and stranding-response work. California Senate Concurrent Resolution 39 became Resolution Chapter 48, Statutes of 2017, recognizing 27 April 2017 as Marine Mammal Rescue Day.

Los Angeles County Board materials in 2026 separately carried a motion concerning 27 April 2026. These reviewed actions are jurisdiction-specific; they do not establish a permanent worldwide holiday or a safe annual date for every future year.

Why Marine Mammal Rescue Day matters

The reviewed California resolution highlighted the work of the Marine Mammal Stranding Network and the rescue, rehabilitation and return of marine mammals off the California coast.

For the public, responsible support means reporting animals to trained responders and keeping a safe distance. A day about rescue is not permission to approach, feed, move, push or medically treat a stranded wild animal.

History of Marine Mammal Rescue Day

California SCR 39 was introduced in 2017 by Senators Toni Atkins and Mike McGuire and ultimately recorded as Resolution Chapter 48, Statutes of 2017. The measure recognized 27 April 2017 as Marine Mammal Rescue Day.

In 2026, Los Angeles County Board materials separately listed a motion to proclaim 27 April 2026 as Marine Mammal Rescue Day throughout the county. This later local action is kept separate from the 2017 state recognition and is not treated as proof of an automatic annual recurrence.
