Embryonic development in Octopus aegina Gray, 1849

Ignatius, Boby and Srinivasan, M (2006) Embryonic development in Octopus aegina Gray, 1849. Current Science, 91 (8). pp. 1089-1092.



Cephalopods occur in all marine habits of the world. They are extremely important in ecological, biological and biomedical research. The genus Octopus consists of more than 100 species and along with Sepia sp. and Sepiella sp. accounts for about 50% of all described cephalopods. Octopus earns valuable foreign exchange for the country. Knowledge on the embryonic and larval development is essential for hatchery and culture techniques. Development stages of the embryo were sequenced based on morphological characters. During the course of development, the embryo reverses its position two times; the new born resembles adults in form except for its free-swimming mode of life. The gestation period of the embryo was 18 to 20 days at a temperature range of 28–30°C.
