Ulva lactuca (Sea lettuce)

Ulva lactuca, commonly known as sea lettuce, is a green, leaf-like marine alga found in oceans worldwide. It has thin, broad, and frilly blades resembling lettuce leaves, growing attached to rocks or other surfaces. Sea lettuce serves as an important part of marine ecosystems, providing food for marine animals like fish and sea urchins, and contributing to oxygen production. It is also harvested for human consumption in some cultures, valued for its nutritional content, particularly vitamins and minerals. Typically thriving in nutrient-rich waters, sea lettuce can sometimes cause overgrowth issues that affect aquatic environments.
