Whale watchers are excited to see whales are feeding near the Farallone Islands.
The giants of sea are in the protected waters of the Gulf of the Farallones Marine Sanctuary but experts say they are in danger.
They are close to busy shipping lanes.
The Marine Mammal Center says a rare fin whale washed up last week with broken vertebrae. Scientists say a ship strike killed the whale and it's likely others will be killed without changes.
Some conservation groups are calling for a new slower speed limit for ships traveling through protected waters. The Gulf of the Farallones says with more than 3,500 ships entering the San Francisco Bay creativity is key.
The agency just started monitoring and documenting where the whales are congregating. Information it will share with ship captains so they can slow down or change shipping channels to avoid the whales. The group is also asking the International Maritime Association to consider changing the shipping lanes to help reduce the number of times whales and ships cross paths.
