A harvestman (a male Phalangium opilio), showing the almost fused arrangement of abdomen and cephalothorax that distinguishes these arachnids from spiders. Harvestmen have a pair of prosomatic defensive scent glands that secrete a peculiar-smelling fluid when disturbed. In some species, the fluid contains noxious quinones.
Aug 4, 2021 · (a) Phalangium opilio draft genome assembly. The draft assembly of the P. opilio genome comprises 580.4 Mbp (37.5% GC content) in 5137 scaffolds (N50: 211 089) and 8349 contigs (N50: 127 429; electronic supplementary material, figure S1 and table S5).
