“Effects range from internal bleeding to manipulating behaviour or liquifying a host.” These are the deadliest weapons in the animal kingdom

Key Points:

• The peacock mantis shrimp delivers one of the fastest and most powerful strikes in the animal kingdom, reaching speeds up to 31 m/s and generating temperatures near 5,000ºC through cavitation bubbles, enabling it to crack open hard shells with forces exceeding 1,500 Newtons.
• On land, the Dracula ant holds the record for the fastest strike, with mandibles closing at 90 m/s in just 23 microseconds, allowing it to pierce insect exoskeletons and feed on their blood.
• Great white sharks possess the strongest bite force among living species, estimated at over 18,000 Newtons, with serrated teeth designed to efficiently tear flesh; they continuously replace teeth as they dull from frequent use.
• Biological weapons have evolved through natural and sexual selection for survival and reproduction, with examples ranging from animal claws and horns to plant structures like milkweed pollen sacs used in male-to-male competition.
• Venoms and toxins serve as chemical weapons in nature, with diverse delivery methods such as cone snails’ harpoon-like radula injecting potent neurotoxins, and mental abilities in some animals, including humans and chimpanzees, enabling the use of tools and strategies as psychological weapons.
