|
Chelus fimbriatus We examined the effects of prey density, presence of a conspecific, and feeding history prior to the experimental period (alone versus group) on the search behavior of Chelus fimbriatus, the side-necked matamata, in the laboratory. The turtles, previously described as ambush predators, changed ambush-sites frequently and moved longer distances when prey density was low, and moved less frequently and shorter distances as density increased in both the single and paired turtle trials. The presence of a conspecific resulted in a decrease in ambush-site changes, in the distance moved, and in the number of prey captured/turtle. Feeding history had no effect on ambush-site changes, distance moved, or number of prey captured. Added by: Admin Last edited by: Beate Pfau |
