| Strongylocentrotus intermedius (A Agassiz, 1864) | |
Strongylocentrotus intermedius is a species of sea urchin described by Alexander Agassiz in 1864.
A chromosome-level genome assembly of Strongylocentrotus intermedius was published in 2026. The genome size is approximately 705 Mb, with 97.77% of the sequence assembled into 21 chromosomes. The assembly has a BUSCO completeness of 91.72%, and 23,127 protein-coding genes were predicted. Comparative genomic analysis identified an expansion of gene families involved in fatty acid biosynthesis, particularly the Elovl gene family.
