Aeoliscus punctulatus, also known as the speckled shrimpfish or jointed razorfish, is a member of the family Centriscidae of the order Syngnathiformes (the pipefishes and seahorses).
This fish adopts a head-down, tail-up position as an adaptation for hiding among sea urchin spines.
It is a transparent pale greenish colour with a brown lateral stripe and a scattering of small black spots.
Its range extends from Algoa Bay, South Africa to Madagascar, the Red Sea, the Persian Gulf, the Seychelles and the Maldive Islands.
It feeds on plankton and is found drifting in small groups in seagrass beds, among the branches of corals and the spines of long-spined sea urchins.
