T FA profile. McMeans et al. [14] lately showed that FA profile of muscle within the Greenland shark could be the most representative of its prey FA profiles. It can be thus assumed right here that the muscle tissue of M. alfredi is representative of its diet, however the extent to which the FA profile of your subdermal connective tissue of R. typus reflects its diet is unknown. Particular species of phytoplankton which includes diatoms, and some macro algae which include Rhodophyta can biosynthesise n-6 PUFA, with levels of over 40 (as wt ) of AA recorded [20, 21]. Though phytoplankton and macro algae happen to be reported in R. typus stomach contents, theyLipids (2013) 48:1029?Table three S1PR3 Biological Activity Polyunsaturated fatty acid composition of chondrichthyan, planktivore, significant pelagic and detrivore species P P Species Feeding habitat Tissue nn- AA EPA DHA three 6 Whale shark–R. typus (mol ) Whale shark–R. typus (wt ) Reef manta ray–M. alfredi (mol ) Reef manta ray–M. alfredi (wt ) Other chondrichthyes Port Jackson shark–Heterodontus portusjacksoni Sandy-backed stingaree–Urolophus bucculentus Southern chimaera–Chimaera fulva Angel shark–Squatina australis Longnose velvet dogfish–Centroselachus crepidater Shortnose spurdog–Squalus megalops South China catshark–Apristurus sinensis Broadnose sevengill shark–Notorynchus cepedianus Planktivores Leatherback turtle–Dermochelys coriacea Jellyfish–Aurelia sp.

The feeding apparatus and feeding tactic of R. typus and M. alfredi are adapted for targeting bigger prey [23, 24]. There is no observational proof of either species targeting phytoplankton, but there are frequent observations o.
