The inner layer of the body wall in certain simple organisms like sea anemones and corals.
From Greek 'entos' (inside) and 'sarx' (flesh). This is a technical anatomical term combining these ancient Greek roots to describe interior body tissues in invertebrates.
When scientists named the layers of sea anemones, they borrowed Greek words like a biological IKEA instruction manual—'entos' means inside, 'sarx' means flesh, so 'entosarc' is literally 'inside-flesh.'
