About
### š Spiral Tube Worms in the Costa del Sol ā Where to See Them Near Estepona & Sotogrande Spiral Tube Worms are one of the Mediterraneanās most delicate and overlooked invertebrates, often surprising divers along the Costa del Sol with their elegant, flower-like appearance. These sedentary polychaete worms build thin calcareous tubes and extend beautiful spiral-shaped feeding crowns that resemble tiny underwater fireworks. Around southern Spain, Spiral Tube Worms can be found on dive sites near Estepona, Casares Coast, Sotogrande, and San Roque. They typically inhabit rocky reefs, shaded walls, caves, and artificial structures between 5 and 40 meters depth. These worms remain fixed inside their tubes and extend their spiral crowns into the water column to filter-feed on plankton and suspended organic particles. Around Estepona and Sotogrande, they are often found on vertical reef faces or under overhangs where currents deliver a steady flow of nutrients. The best time to observe Spiral Tube Worms along the Costa del Sol is during calm conditions with good visibility, especially in the morning or late afternoon when feeding activity is more visible. In areas like Casares and San Roque, they are commonly spotted in shaded reef sections where light and current conditions are ideal. For divers and macro photographers, Spiral Tube Worms are a subtle but rewarding subject. Their intricate spiral crowns, delicate movements, and varied colors make them ideal for close-up photography and a great example of the Mediterraneanās hidden biodiversity. Whether youāre diving near Sotogrande or exploring rocky walls around Estepona, spotting Spiral Tube Worms adds a quiet but beautiful detail to any Costa del Sol diving experience.
