Arthropod acoustic communication is a primary focus at the Patek Lab. Here you can find our acoustically oriented research projects along with sounds and video of spiny lobsters (Palinuridae) and mantis shrimp (Stomatopoda).
High speed video of Lysiosquillina maculata striking prey
High speed images show Lysiosquillina maculata grabbing prey with both appendages. The dactyl first rotates outward and is followed by the rapid swing of the propodus. The prey is captured between the inner most dactyl spines and the propodus. Moveable propodus spines are raised during propodus rotation. This sequence was recorded at 3000 frames s-1 and played at 60 frames s-1.
