 BackHome19K is the first comprehensive seashell image dataset specifically created for ecosystem-level classification—distinguishing between shells from the Pacific and Caribbean coasts—rather than traditional taxonomic identification.
 
-The dataset includes 19,058 high-quality images of 516 marine mollusk species, from within 84 families, collected with the support of the School of Biology at the University of Costa Rica. It features a wide range of gastropods and bivalves, from families such as Cypraeidae, Cassidae, Ostreidae, Veneridae, and others.

 This collection addresses the challenge of visually similar species across different ecosystems and supports research in geographic origin inference, morphological pattern analysis, and marine biodiversity.
