Specimen 091
A relatively large specimen of Amoeba proteus. Amoebas are fascinating single-celled organisms that are known for their ability to move and engulf prey using a unique structure known as pseudopods. Pseudopods are temporary, finger-like projections that are used for a variety of functions, including movement, feeding, and communication. One of the most important functions of pseudopods is movement. Unlike many other single-celled organisms that rely on cilia or flagella to move, amoebas use pseudopods to propel themselves forward. The process of pseudopod-based movement is called amoeboid motion, and it involves the extension of a pseudopod in the direction of movement, followed by the contraction of the rest of the cell toward the pseudopod. This creates a forward movement of the cell. However, this form of locomotion is very slow-moving and sometimes hardly perceptible - this video recording had to be speeded up by about 5 times. |
