Good spots for shore-based marine life observation (turtles, fish, rays) without entering water?

Some beaches and rocky areas, especially around Hikkaduwa, Unawatuna, and certain east coast spots, allow good shore-based observation of turtles, rays, and fish in shallow water, particularly early morning or late afternoon. Local knowledge helps identify the best current spots, as conditions change. Binoculars or a good zoom lens can enhance the experience without entering the water. Always be mindful of not disturbing wildlife or their habitat. Some areas near river mouths or lagoons also have interesting shore-accessible marine life.
