Shoal in rivers, streams, and lakes. A shoal–sandbar may seasonally separate a smaller body of water from the sea, such as: The term "bar" can apply to landform features spanning a considerable range in size, from a length of a few metres in a small stream to marine depositions stretching for hundreds of kilometers along a coastline, often called barrier islands. They are typically composed of sand, although they could be of any granular matter that the moving water has access to and is capable of shifting around (for example, soil, silt, gravel, cobble, shingle, or even boulders).

Granular cell tumor Granular cell tumor Granular cell tumor is a tumor that can develop on any skin or mucosal surface, but occurs on the tongue 40% of the time. It is also known as Abrikossoff's tumor, Granular cell myoblastoma, Granular cell nerve sheath tumor, and Granular cell schwannoma.)Granular cell tumors (GCTs) affect females more often than males. Granular cell tumors show similarity to neural tissue, as can be demonstrated by immunohistochemistry and ultrastructural evidence using electron microscopy. Multiple granular cell tumors may seen in the context of "LEOPARD syndrome", due to a mutation in the "PTPN11 gene". These tumors on occasion may
