Photokinesis, one of the most tangible aspects of sponge larval behavior, is best known from studies on parenchymellae larvae of demosponges (Warburton, 1966; Bergquist and Sinclair, 1968; Bergquist et al., 1970; Wapstra and van Soest, 1987; Woollacott, 1990, 1993; Maldonado and Young, 1996, 1999).
Cytological basis of photoresponsive behavior in a sponge larva
Photic responses included tests for photokinesis (freeze time in response to a directed light source), phototaxis (directional movement in response to a directed light source), and photophilia (percentage of time spent in light).
