A sea mat is a colony of tiny aquatic invertebrates called bryozoans. These colonies form a delicate, lace-like structure that resembles a mat or seaweed. They're filter feeders, using tentacles to catch tiny particles from the water. Imagine them as underwater apartment complexes where each little resident is having a meal. Sea mats are often found attached to rocks, seaweed, or other submerged surfaces. Think of them as the ocean's carpet, but way cooler and alive! 🌊
