The jumping behavior of Strobilidium velox and Halteria grandinella was analyzed videographically. On average, undisturbed cells of these species jumped 1.7–3.6 and 8 times per minute and spent 0.8 and 1.0% of their time jumping, respectively. Both ciliate species initiated jumps after encounters with rotifer predators. S. velox jumped on contact with Asplanchna girodi, traveling a mean distance of 1.5 mm (33 body lengths) at a mean velocity of 7 mm/s (154 body lengths/s) at 17°C. H… CONTINUE READING
