The incredible video was captured Friday March 29 by the Princess Monterey Whale Watching group.
According to photographer Randy Straka, the huge 'superpod' consisted of several hundred Northern Right Whale Dolphins, which rarely appear in Monterey Bay.
The dolphins get their name because they lack a dorsal fin, similiar to the Northern Right Whale.
The dolphins can be seen leaping out of the water and swimming underneath the whale watching boat.
'Superpods' of dolphins are rare but they have been spotted before in Monterey Bay.

Just last year the Monterey Bay Aquarium captured video of a 'superpod' of common dolphins swimming in the bay.
The Aquarium estimated that 'superpod' consisted of nearly a thousand dolphins.
The marine mammals are highly social and often congregate in large groups, but superpods are still a rare occurrence.
