Consider the following statements: 1. The common blue green algae Spirogyra and Ulothrix are found in both fresh water ponds and oceans. 2. The chameleon can look ahead with one eye, and at the same time look behind with another. Which of these statements is/are correct?

Statement 1 is incorrect. Spirogyra and Ulothrix are filamentous green algae (Chlorophyta) typically associated with freshwater habitats; Spirogyra is widely distributed in freshwater ponds and streams [3], and green algae in general are characteristic of freshwater environments as opposed to marine red or brown seaweeds [1]. Ulothrix is also listed among green algal genera (not cyanobacteria) and is not generally described as a common marine blue‑green alga [2]. Statement 2 is correct: chameleons have highly mobile, independently rotating eyes, enabling monocular scanning in different directions simultaneously (for example, looking forward with one eye while the other looks to the rear).
