Qualitative and quantitative distribution of planktonic cephalopods in the Exclusive Economic Zone of the west coast of India

The cephalopod larvae and juveniles in plankton samples collected during the first 10 cruises of FORV Sagar Sampada off the west coast of India from February to December, 1985 have been studied for their qualitative and quantitative distribution. The samples were obtained in Bongo net operations carried out in an extensive area covering Lat. 4° to 23° N and Long. 65° to 77° E. Out of the total 258 stations sampled, cephalopods were obtained in 110 stations in varying numbers. The estimated number of cephalopods per haul ranged between 1 and 112. Of the total number of hauls in which cephalopods obtained, 51% occurred in night hauls and the rest in day hauls

Some observations on parental care in Octopus dollfusi Robson (Cephalopoda : Octopodidae)

Some of the octopi are well known for their complex behaviour during the brooding period. The present paper describes certain remarkable habits observed in a brooding adult of Octopus dollfusi Robson. O. dollfusi appears to be a species of restricted distribution, having been recorded so far only from Nias, Amoy, and Ennore (Madras) (Adam, 1960 and 1962). However it seems to be a common littoral form on the southeastern coast of India
