Abstract Background Venom glands play a key role in the predation and defense strategies of almost all spider groups. However, family Uloboridae lacks venom has evolved an adaptive strategy: they excessively wrap their prey directly with silk instead paralyzing it first toxins. This shift survival strategy is very fascinating, but genetic underpinnings behind are poorly understood. Results Spanning multiple groups, we conducted multiomics analyses on Octonoba sinensis described evolution at...
