Philodina sp. – 200x
This Bdelloid rotifer (Philodina sp.) was found in water collected from Little Fishweir Creek in Boone Park (Jacksonville, FL). This class of rotifers is most interesting for three reasons: 1) It reproduces asexually 2) it’s capable of long-term dormancy as a cyst (following desiccation) 3) It may be capable of horizontal gene transfer when “waking” from cyst mode.
This species’ mastax appears to consist of two-churning discs which help break down its food (primarily algae). The discs are in near-constant motion.
The video is recorded using a 20x eyepiece and a 40x objective (800x).
