Fissurella afra has on ovate-oblong and convex shell. The bull-fish within it is painted with brownish-violet rays and is white within. For the rest it is ovate, conicale, and obtuse at its summit; its fissure is ovate and contracted in the middle. Fissurella afra is also very finely striated radiately, and marked in the same way with radiating bands of a violaceous-brown on a yellowish-white ground.

Seashore wildlife habitats exist from the Tropics to the Arctic and Antarctic. Seashores and beaches provide varied habitats in different parts of the world, and even within the same beach. Phytoplankton is at the bottom of some food chains, while zooplankton and other organisms eat phytoplankton. Kelp is also autotrophic and at the bottom of many food chains. Coastal areas are stressed through rapid changes, for example due to tides.
