Behavioral disruptions caused by dechorionation. a Early-dechorionated larvae have disrupted negative gravitaxis (upward swimming). (Percentages are derived from three separate clutches and two movies per clutch; see text for details.) b The negative gravitaxis behavior of late-dechorionated larvae more closely resembles non-dechorionated controls than do early-dechorionated larvae. (Percentages are derived from two separate clutches and two movies per clutch.) c Representative dimming-induced swims in non-dechorionated, late-dechorionated, and early-dechorionated larvae. Lines represent swim trajectories projected across 20 s. d Both early- and late-dechorionated larvae swim more slowly than do non-dechorionated controls
