Abstract:
Cerastoderma glaucum is a key intertidal bivalve in the north-east Atlantic, serving as a trophic resource for fish and birds. Its mitochondrial genome comprises 14,953 bp, encoding 13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes. Gene structure resembles Cerastoderma edule but lacks an additional methionine tRNA. Phylogenetic analysis revealed close affinity between Baltic and English samples (p-distance = 0.027). No mitochondrial heteroplasmy was detected in mature male gonads, suggesting C. glaucum is not a doubly uniparental inheritance (DUI) species. These findings contribute to understanding mitogenomic variation and reproductive biology in bivalves inhabiting dynamic coastal ecosystems .
