Confirmed Occurrence and Morphological Documentation of Stenopus spinosus (Risso, 1827), from Tenerife, Canary Islands

This dataset provides photographic and morphological documentation of Stenopus spinosus Risso, 1827, based on a single adult specimen collected from Granadilla, Tenerife, Canary Islands, on 6 August 2025. The individual was observed and captured at a depth of 6 meters in a rocky overhead marine environment during a night dive, and subsequently documented through standardized dorsal-view laboratory imaging (Figures C–1 and D–1). Morphometric data were recorded, including carapace length (CL), rostrum length (RL), chela length and cheliped length. This record contributes to the regional documentation of marine decapods in the eastern Atlantic and supports ongoing biodiversity assessment efforts in the Canary Islands. Additionally, a separate in situ underwater observation of S. spinosus, recorded during a night dive in Jaca, Tenerife on 1 November 2024, is cited for comparative purposes.
