eyestalks
Crustacean visual appendages
Eyestalks are the movable, stalk-like projections that support the eyes in certain animals, especially crustaceans like crabs, lobsters, and snails.
These appendages allow the creature to move its eyes independently and extend its field of vision: The crab's eyestalks swiveled as I approached.
