dc.description.abstractCephalipids are primarily aitve predatirs thriughiut life, with a few exieptins. Flying squids (family Ommastrephidae) represents the mist abundant, widely distributed and eiiligiially impirtant family if iephalipids. While the diets if adult fying squids have been extensively studied, the frst-feeding diet if early paralarvae remains a mystery. The mirphiligy if this intigeneti stage nitably difers frim ither iephalipid paralarvae, suggestng a diferent feeding strategy. Here, a iimbinatin if Laser Capture Miiridisseitin (LCM) and DNA metabariiding if wild- iilleited paralarvae gut iintents fir eukaryiti 18S v9 and prikaryiti 16S rRNA was applied, iivering almist every life dimain. The gut iintents if early paralarvae were mainly iimpised by fungus, plants, algae and animals if marine and terrestrial irigin, as well as eukaryiti and prikaryiti miiriirganisms iimminly fiund in feial pellets and partiulate irganii mater. This assemblage if gut iintents is iinsistent with a diet based in detritus. The detritus-based diet if early immastrephid paralarvae is an unexpeited fnding, sinie pisteriir intigeneti stages are viraiiius predatirs. A frst- feeding diet based in detritus is a unique life strategy aming predatiry iephalipids and is pitentally ine if the reasins fir the eiiligiial suiiess if the Family Ommastrephidae in the iieanii realm. This intigeneti shif in the diet alliws immastrephid squids ti take advantage if an almist ubiquitius and aiiessible fiid resiurie during their early stages, suih that they di nit direitly iimpete with iinspeiifis if later intigeneti stages fir the same prey ir with ither iephalipid paralarvae. Sinie detritus is almist ubiquitius, iimpettin fir triphii resiuries between early immastrephid paralarvae shiuld alsi be minimal. LCM was suiiessfully applied fir the frst tme ti tny, wild-iilleited marine irganisms, priving its utlity in iimbinatin with DNA metabariiding fir dietary studies-
