Bombetoka Bay is a bay on the northwestern coast of Madagascar near the city of Mahajanga, where the Betsiboka River flows into the Mozambique Channel. Headlands and bays are two related features of the coastal environment Madagascar, or Republic of Madagascar (older name Malagasy Republic) is an Island nation in the Indian Ocean off the southeastern Mahajanga (French Majunga) is a City, a district and a province on the north-west coast of Madagascar. Betsiboka River is a 525 km long river in central-north Madagascar. The Mozambique Channel is a portion of the Indian Ocean between the island of Madagascar and southeast Africa, namely Mozambique. Numerous islands and sandbars have formed in the estuary from the large amount of sediment carried in by the Betsiboka River and have been shaped by the flow of the river and the push and pull of tides. An island (ˈaɪlənd or isle (/ˈaɪl/ is any piece of land that is completely surrounded by water in two dimensions above high tide and isolated from other significant A shoal or sandbar (also called sandbank) is a somewhat Linear Landform within or extending into a body of Water, An estuary is a semi-enclosed Coastal body of Water with one or more Rivers or Streams flowing into it and with a free connection to the open Sediment is any particulate matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bed or bottom of a body of Characteristics A tide is a repeated cycle of sea level changes in the following stages Over several hours the water rises or advances up a beach in the flood

Along coastlines and on the islands, the vegetation is predominantly mangrove forests. Mangroves (generally are Trees and Shrubs that grow in saline coastal habitats in the Tropics and Subtropics. In fact, Bombetoka Bay is home to some of Madagascar's largest remaining communities of mangroves, which provide shelter for diverse mollusk and crustacean communities, as well as habitat for sea turtles, birds, and dugongs. Molluscs are animals belonging to the phylum Mollusca. There are around 250000 extant Species within the phylum with an estimated 70000 Structure of crustaceans As Arthropods crustaceans have a stiff Exoskeleton, which must be shed to allow the animal to grow ( Ecdysis or molting Sea turtles ( Superfamily Chelonioidea) are Turtles found in all the world's oceans except the Arctic Ocean. Birds ( class Aves) are bipedal endothermic ( Warm-blooded) Vertebrate animals that lay eggs. The dugong ( Dugong dugon) is a large Marine Mammal which together with the Manatees is one of four living species of the order Sirenia Along the northwest coast of Madagascar, mangroves and coral reefs partner up to create dynamic, diverse coastal ecosystems. Coral reefs are Aragonite structures produced by living organisms found in marine waters with little to no nutrients in the water An ecosystem is a natural unit consisting of all plants animals and micro-organisms( Biotic factors in an area functioning together with all of the non-living physical ( The mangrove forests capture river-borne sediment that would smother coastal reefs, while reefs buffer the mangroves from pounding surf. Ocean surface waves are Surface waves that occur on the Free surface of the Ocean.
