AB Terminal repeat retrotransposons in miniature (TRIMs) are small non-autonomous LTRretrotransposons consisting of two terminal direct repeats surrounding a short internal domain. Thedetection and characterization of these elements has been mainly limited to plants. Here we presentthe frst fnding of a TRIM element in bivalves, and among the frst known in the kingdom Animalia.Class Bivalvia has high ecological and commercial importance in marine ecosystems and aquaculture,and, in recent years, an increasing number of genomic studies has addressed to these organisms.We have identifed biv-TRIM in several bivalve species: Donax trunculus, Ruditapes decussatus,R. philippinarum, Venerupis corrugata, Polititapes rhomboides, Venus verrucosa, Dosinia exoleta,Glycymeris glycymeris, Cerastoderma edule, Magallana gigas, Mytilus galloprovincialis. biv-TRIM hasseveral characteristics typical for this group of elements, exhibiting diferent variations. In addition tocanonically structured elements, solo-TDRs and tandem repeats were detected. The presence of thiselement in the genome of each species is <1%. The phylogenetic analysis showed a complex clusteringpattern of biv-TRIM elements, and indicates the involvement of horizontal transfer in the spreading ofthis element
