This is a study on the effects parental exposure of elevated CO 2 on the reproduction and embryonic development of the two-toned pygmy squid ( Idiosepius pygmaeus ). Adult squid were exposed to either control or elevated CO 2 conditions for 14 days prior to being paired together to breed. After eggs were spawned, they were counted and photographed under microscope. The development of the embryos was then recorded with photographs (every 24 hours) until all embryos had hatched. From the photographs and count data, variables of development and reproduction were collected including number of eggs per clutch, percent of eggs that were fertile, percent of embryos that were deformed, number of embryos to hatch, time it took them to hatch from spawning, as well as size of the egg cases and embryos during distinct stages of embryonic development. These variables were compared to determine if there was an effect of elevated CO 2.

Cephalopods are ecologically important in marine ecosystems, yet the potential effects of elevated CO 2 on cephalopod reproduction and embryonic development are little studied.
