This is Amoeba proteus at 600x. You can check my previous video to see it in lesser magnification. I wanted to share this video to show the huge nucleus, It contains the cell's genetic material. A. proteus has been described as uninucleate, it means having a single nucleus. Nucleus can be easily seen in this video, the big ovoid one with granules. Also you can see many food vacuoles in the cells cytoplasm. A. proteus feeds on other protozoans, algae, rotifers, and even other smaller amoebae. Isn
