Would be the most representative of its prey FA profiles. It is actually hence assumed right here that the muscle tissue of M. alfredi is representative of its diet, but the extent to which the FA profile in the subdermal connective tissue of R. typus reflects its diet is unknown. Particular species of phytoplankton like diatoms, and a few macro algae for example Rhodophyta can biosynthesise n-6 PUFA, with levels of more than 40 (as wt ) of AA recorded [20, 21].

The feeding apparatus and feeding method of R. typus and M. alfredi are adapted for targeting bigger prey [23, 24]. There is no observational evidence of either species targeting phytoplankton, but you can find frequent observations of feeding on zooplankton patches. More plausibly, n-6 LC-PUFA from phytoplankton could enter the.
