Regulation of venom composition by the Australian funnel-web spider Hadronyche infensa is achieved via compartmentalised toxin production and venom metering

Key Points

• Venom composition regulation impacts toxicity profiles and prey capture efficiency, crucial for survival.
• Key evidence shows that compartmentalized production of neurotoxins enables targeted delivery during predation.
• Analysis of spider physiology reveals intricate systems for toxin production and venom metering, ensuring efficient usage.
• Understanding venom regulation may inform ecological dynamics and potential therapeutic applications.
