Caretta carom, cpibiontes, Mar Mediterráneo, Polysiphonia carettia.Pelagic animals, such as cetaceans andsea turtles, are a singular habitat for growth ofbenthic organisms. The loggerhead turtle,Caretta caretta (Linnaeus, 1758), is a speciesthat can sometimes become an "ecosystem"itself because it support a very rich flora (Cribb,1969; Abel Sentfes et al., 1999) and fauna(Frazier et al., 1985; Caine, 1986; Frick et al.,1998; Frick et al., 2000) occurring as epizoicorganisms.Several studies on epibionts of loggerheadturtles have been carried out from samplescollected on female individuals during egglaying events that took place on beaches. Dodd(1988) found 5 genera of seaweeds growing onC. caretta, but they were identified in thatpaper only as green or red algae, withoutspecific designation. Ninety-three species ofepibionts (including 7 identified genera of algaeas well as other unidentified green algae anddiatoms) have been recorded on C. carettafrom the North American shores of the AtlanticOcean (Caine, 1986; Frick eta!., 1998). AbelSentíes et al. (1999) reported 37 species ofseaweeds growing on C. caretta from theCaribean coasts of Mexico. Recently, Frick etal. (2000) found 7 new algal species on C.caretta, among which an unidentified greenalga.Frazier et al. (1985) carried out a revisionof the epibiont molluscs of C. caretta from theeastern Mediterranean Sea mentioning thepresence of Sphacelaria tribuloides Menegh.,Chaetomorpha linutn (0.F. Müller) Kiitz.,Cladophora sp. and Polysiphonia sp. As far aswe know, this is the only study of epibionts ofC. caretta carried out in the MediterraneanSea.We now report the first record ofPolysiphonia carettia Hollenberg in theMediterranean Sea. The samples were obtainedfrom two individuals of loggerhead turtle. Bothanimals had a shell 39 cm in minimum strength4504Ø0350Figure 1.

Distribution of Polysiphonia careitiaHollenberg on the loggerhed turtle carapace (obliquelines area).carapace length (MSCL); therefore, they wereprobably young individuals because the shellof adult individuals usually measures around74 cm in MSCL (Marquez, 1990). They werecaptured by a spanish longline vessel onOctober 30th 1999, at 38°12'69"N001°29'62'E (fig. 1). The algae, distributedon the carapace as shown in figure 2, werecollected by scraping the shell carapace of theturtles with a diver's knife. The samples werepreserved in 4% formalin-seawater. They weredeposited at Herbarium of the Department ofPlant Biology, University of Malaga (MGCPhyc). They were a cession from the InstitutoEspañol de Oceanografía. The turtles werehandled carefully in order to preserve the healthof the animals.Polysiphonia carettia Hollenberg(Ceramiales, Rhodomelaceae), MGC Phyc3742This species is characterized by its red-brown, uncorticated thallus of 0.5-4 cm inlength, with four pericentral cells surroundingone axial cell, which is smaller in diameterthan the pericentral cells (fig. 3.1). The thalluspresent creeping axes attached by unicellularrhizoids, which initially are in open connectionwith pericentral cells (fig. 3.2) and, when fullydeveloped, cut off by a cross wall (fig. 3.3).Erect axes have a sparse, irregular branchingpattern in the basal and middle portions,whereas the branching is irregular and dense inthe distal part. Erect segments are longer thantheir width (ratio length/width= 1.3) and beardeciduous trichoblasts. Tetrasporangia arespherical and are disposed in a spiral series inthe distal branches (fig. 3.4); they measureover 40-43 j_tm in diameter. Cystocarps areovoid-urceolate, with a short peduncle, andmeasure up to 216 pm in length and 144 p.m indiameter. The pericarp is formed by irregularlydistributed polygonal cells similar to the cellsof the ostiole (fig. 3.5). The carpospores arepyri form and up to 70-80 p.m in length and 30-33 ¡.tm in diameter. No spermatangial brancheswere found.Polysiphonia carettia has been reportedon the shells of nesting loggerhead turtles inCalifornia (Hollenberg, 1971), Canary Islands(Rojas-González eta!., 1994) and the CaribbeanSea (Abel Sentfes et al., 1999). Thegeographical distribution of P. earettia isextended with this study to the MediterraneanSea.In the Northern Hemisphere, loggerheadturtles make use of two nesting regions in thenorth Atlantic Ocean and in the MediterraneanSea: the one is located on the southeasternshores of the USA and the Gulf of Mexico; theother one in the eastern Mediterranean(Margaritoulis, 1982; Márquez. 1990). It hasbeen proposed that the population from thewestern Mediterranean Sea contains individualsfrom both nesting regions, which use this area(and mainly surrounding Balearic Islands) as afeeding area, particularly during spring andsummertime (Camitias, 1997a). Previously thisspecies was recorded only from in the AtlanticOcean. Although Frazier et al. (1985) recorded50 pm199Acta Botanica Malacitana 26. 200123 RE s=c--100 pm30 pmFigure 3. Polysiphonia carettia Hollenberg. 1, cross section of axes; 2-3, postrate axes with unicellularrhizoid; 4, teirasporangial branches; 5, branch with cystocarp.Polysiphonia sp. growing on Ostrea edulisLinnaeus (occurring as an epibiont on C. carettain the eastern Mediterranean Sea), we thinkthat species could not he P. carettia becausethis taxon has always been found on theloggerhead turtle and not on any othersubstratum (Hollenberg, 1971; Hollenberg andNorris, 1977; Rojas-González eta!., 1994; AbelSentíes et al., 1999). It is known that thepopulations of loggerhead turtles from theeastern Mediterranean Sea are geneticallyisolated from the population from the westernarea (Laurent eta!., 1998). Thus, the finding ofP. carettia growing on young individual ofloggerhead turtles in the western MediterraneanSea could be explained by a migratoryhypothesis, that is, some young turtles foundin that area could come from Atlanticpopulations and have penetrated into thewestern Mediterranean Sea through the Straitof Gibraltar (Camitlas, 1992, 1995, 1997b;Bolton eta!., 1998). By this line of reasoning,it could be interesting to study the epizoicalgae growing on loggerhead turtles of thewestern Mediterranean Sea, in order todistinguish the Atlantic from the easternMediterranean populations of loggerheadturtles. Thus, P. carettia could be used as abiological marker to distinguish the loggerheadturtles coming from the Atlantic Ocean andfound in the western Mediterranean Sea, fromthose coming from the eastern Mediterranean200	 Acta Botanica Malacitana 26. 2001Sea. However, it is necessary to study manymore samples of algae growing on loggerheadturtles from both the western and easternMediterranean Sea in order to test thishypothesis.The samples of P. carettia studied showrhizoids that when fully developed were cutoff by a cross wall, in agreement with theobservations from Rojas-González et al.(1994). In the original description of the taxon,Hollenberg (1971) described rhizoids that werenot cut off by a cross wall (as shown in fig.3.2), but based on these more recentobservations we believe that this character inthe original description must be revised (seefig. 3.3). On the other hand, our samples arebigger (up to 4 cm in length) than the thallifound in the Canary Islands by Rojas-González(1997) (up to 2 cm in length) and withtetrasporangia of greater diameter.ACKNOWLEDGEMENTS.
