The Hydra was a monster from Greek mythology with many snake-like heads. If you cut off one head, two more would grow back. It lived in the Lernaean marshes near Argos. Heracles, a Greek hero, had to defeat the Hydra as one of his twelve challenges. With help from his nephew Iolaus, they found a way to stop new heads from growing by burning the stumps after cutting them off. After beating the Hydra, Heracles used its poisonous blood to make his arrows deadly. #hydra #mythology #snakehead #reelsv

When prey hits the hydra’s tentacle a neurotoxin is released that immediately paralyzes the victim. The hydra will then slowly contract its arms and transport the prey towards its mouth to be eaten alive! #MicroscopicMonday 🔬 | Science Channel
