Cattle egret and grazing cattle exhibit close association. Egrets always forage close to the grazing cattle since the cattle stir up the vegetation while moving. This flushes out the insects from the vegetation and egrets feed on them. Without a grazing cattle, egrets find it difficult to locate and catch the insects. Since egrets are benefited from the association, it is mutualism.
Blood cells are a lot smaller than nerve cells and have a disc-shaped structure, both great traits for moving quickly through small spaces. Their disc shape also provides them with a big surface where lots of oxygen can enter the cell.
