Paramecium vs Homalozoon: Microscopic Battle of Harpoons! ⚡🦠 #Microscopy” Meet Homalozoon, a long worm-like unicellular organism, attempting to feed on a Paramecium—but this time, Paramecium’s defenses are flawless, letting it slip away unharmed. Both Homalozoon and Paramecium belong to a group of single-celled organisms called ciliates. Even with just one cell, ciliates display incredibly complex strategies for hunting and defense—one of the many reasons I chose to specialize in studying them.
