நஞ்சுள்ள இந்த உயிரினங்கள் ஆபத்தானவையா? | தொட்டுவிடாதீர்கள்! Planarian, Hammerhead and Ribbon worms

1. Planarian Worm ​Video: Want a Whole New Body? Ask This Flatworm How | Deep Look Planarians are small, cross-eyed flatworms found in water that possess an extraordinary superpower: extreme regeneration. ​Regeneration: If a planarian is cut into pieces—even just a chunk with no head or tail—it can regrow its entire body. ​The Process: ​Overnight, the wound heals closed. ​It grows a white tissue called a "blastema" where new parts form. ​Within a week, tiny new eyes appear, and by day 12, it has a fully formed head, tail, and pharynx (feeding tube). ​After three weeks, the worm looks completely normal. One worm can be cut to create multiple new individuals. ​How they do it: This ability is due to powerful stem cells that make up one-fifth of their body, which can transform into any cell type needed. ​2. Hammerhead Worm ​Video: Hammerhead Worm | The Immortal Worm The Hammerhead worm (Bipalium) is a predatory land flatworm known for its distinctive shovel-shaped head and "immortality." ​Immortality: Like planarians, they are essentially immortal because they reproduce via fragmentation. If cut into pieces, each section can regenerate into a fully developed organism within a few weeks. ​Predatory Behavior: They hunt earthworms, snails, and slugs using muscles covered in sticky secretions to trap prey. ​Toxicity: They contain a potent neurotoxin (Tetrodotoxin), the same toxin found in pufferfish, making them dangerous to eat for predators. ​Invasive Species: Native to Asia and Madagascar, they have been transported to Europe and North America, where they are considered invasive pests. ​3. Ribbon Worm ​Video: Discover the Ribbon Worm: The Unusual Hunter with a Sticky Weapon Ribbon worms are often described as "alien-like" due to their unique hunting mechanism. ​The Proboscis: Their defining feature is a retractable, muscular tubular structure called a proboscis. ​Hunting: When it encounters prey, it rapidly shoots out this web-like proboscis, which is coated in sticky mucus. ​Feeding: The proboscis can extend several times the length of the worm's body to entangle prey. The worm then consumes the prey by swallowing it whole or injecting digestive enzymes to liquefy it. ------------------------------------------------------------------------ Welcome, We explore the universe, from the farthest reaches of space to the hidden wonders of nature here on Earth.
