Note

Date: February 2025 Depth: 26 meters Dimensions: 90.0 mm (maximum shell length, without matrix) Condition: Anatomical pale morph. GEM This listing features a pale chromatic form of Spondylus senegalensis (Schreibers, 1793), (d/c) with decomposed soft tissue, collected at 26 meters depth during a certified marine infrastructure assessment conducted in the port area of Tenerife, Canary Islands.. The specimen exemplifies a markedly desaturated phenotype, characterized by its light beige to ivory shell coloration — a rare variation within this typically dark red to purple species. Unlike the typically saturated dark red phenotypes observed in S. senegalensis, this individual exhibits a markedly desaturated, light beige chromatic profile. Such hypopigmented phenotypes are rarely encountered and may be attributable to site-specific factors including substrate reflectivity, turbidity levels, or reduced carotenoid assimilation. These traits make the specimen particularly relevant to investigations into pigment variability, phenotypic plasticity, and habitat-influenced morphogenesis within the Spondylidae. The shell displays complete peripheral spine development, with all radial and lamellar elements intact. No mechanical wear, bioerosion, or post-mortem degradation is evident. The preservation state allows for high-resolution morphological and anatomical study, offering a stable reference point for comparative taxonomic and biometric analyses. -Condition: Museum-grade; 90.0 mm -Colouration: pale beige to ivory hue across the entire valve surface. Represents a hypopigmented phenotype—rare within the species and potentially indicative of environmental modulation or low carotenoid bioaccumulation. -Spination: Peripheral spines fully developed and entirely intact; no signs of mechanical abrasion or post-mortem loss. Spine architecture sharply preserved, enabling high-fidelity morphometric analysis. -Collection Depth: 22–28 m -Collection Method: Recovered during certified marine infrastructure survey -Substrate: Benthic artificial (harbor structures, container boat cleaning) -Water Temperature: 20.4°C -Salinity: ~36 ppt -Visibility: ~4 metres -Current: Strong -Locality: industrial zone, Tenerife, Canary Islands -Value:(€650.00) = %€450.00% ( https://coralliophila.com/spondylus-senegalensis-schreibers-17932 )
