An endoparasitic organism lives inside its host, feeding off it from within. 🦠 Think of it like a freeloader who's also a total jerk, causing harm while mooching. Unlike ectoparasites which live on the surface, these guys are internal invaders. They can be bacteria, worms, or even certain plants. Imagine a tiny alien living in your stomach, stealing all the pizza nutrients. 🍕 Endoparasites often have complex life cycles involving multiple hosts. Basically, they are the ultimate unwelcome guests.
