The Undersea World of Jacques Cousteau S01 E09 The Night of the Squid

The crew observes as 20 million squid amass in coastal waters to mate, spawn and die. In the waters off southern California the Calypso happens upon the savage, yet touching, spawning ritual of the sea arrow squids of the Pacific. From their exotic mating dance to the microscopic battle for survival of the newly-hatched young, the entire cycle is captured on film by the crew.
