Fatty Acid (FA) composition in % of total PLFA of deep-sea demosponge species (order Tetractinellida): Geodia atlantica ( Ga ), G . barretti ( Gb ), G . hentscheli ( Gh ), G . parva ( Gp ) and Stelletta rhaphidiophora ( Sr ).
FA names are given in ω and Δ notation and a hybrid form, with corresponding total C atoms (C) and equivalent chain length (ecl). FA categories match with those of Fig 2 . Only FAs with abundance ≥1% (in at least one species) are shown. Numbers in bold are ≥ 10% of total FAs.
