Shell Blade

Shell Blades (シェルブレード, Sheru Bureedo) are aquatic clam-like enemies that will lunge at you if you get too close. When they do this, block with your shield or move out of the way. They will stop and eventually open up, exposing their muscle ligaments which you can attack with the Hookshot in Ocarina of Time, as Zora Link in Majora's Mask, and with the clawshot or sword in Twilight Princess. They are considered very annoying. In Majora's Mask, Shell Blades guard some of the stolen Zora eggs in Pirates' Fortress.
