From Science News Blog:
C.C. – a giant Pacific octopus at the Vancouver Aquarium – laid a large batch of eggs last October. 300 of the eggs hatched earlier this month. Some of the giant Pacific octopus babies can be seen in the video below. The tiny babies are only 5 millimeters in length.
Dr. Dennis Thoney, director of Animal Operations at the Vancouver Aquarium, says, “Although it is not unusual for octopus eggs to hatch in aquariums, very few hatchings have ever survived. Chances of survival are very low because giant Pacific octopuses have a seven to ten month long pelagic larval stage. To further our knowledge of octopus reproduction, we will attempt to feed and maintain some [of] the larvae for as long as possible.”
