This defense mechanism is known to clog the predator’s gills during an attack — forcing the predator to release the hagfish to avoid suffocation. 缾 | Science Channel | Facebook

Happy #HagfishDay! Never seen a #hagfish before? The hagfish is a slime-emitting ocean-dweller that's remained unchanged for 300 million years--and it shows. It has a skull (but no spine), velvet smooth skin, and a terrifying pit of a mouth that’s lined with rows of razor-sharp teeth. 🎥Crazy Monster | Smithsonian Channel
