The burrowing sponges Anthosigmella varians and Spheciospongia vesparium were found to be rich in the isoprenoid phospholipid fatty acid 4,8,12-trimethyltridecanoic (5.2% and 23%, respectively, of the total fatty acid composition), while the burrowing sponge Chondrilla nucula and the demosponge Agelas dispar contained the acid 3,7,11,15-tetramethylhexadecanoic (13.8% and 8.6%, respectively, of the total phospholipid fatty acid composition). No other isoprenoid fatty acid was found, and the two acids described in this work did not occur concomitantly in the same sponge.
研究发现，掘穴海绵物种Anthosigmella varians和Spheciospongia vesparium富含类异戊二烯磷脂脂肪酸4,8,12-三甲基十三烷酸（分别占总脂肪酸组成的5.2%和23%），而掘穴海绵Chondrilla nucula和寻常海绵纲的Agelas dispar则含有3,7,11,15-四甲基十六烷酸（分别占总磷脂脂肪酸组成的13.8%和8.6%）。未发现其他类异戊二烯脂肪酸，且本文所述的这两种酸未在同一种海绵中同时出现。
