| The epaulette shark's slender body is slightly flattened with a rounded snout, two short nasal barbels, and large spiracles. |
| All four barbels are evenly spaced under the jaw, unlike the related pallid sturgeon, which has barbels unevenly spaced under the jaw. |
| Sturgeon species are noted by a spindle-shaped body with five rows of bony scutes and a long snout with sensory barbels. |
| These barbels hang below the mouth and feel the bottom as the sturgeon swims. |
| Red mullet search the sand in hordes, feeling for suitable small animals with their long barbels. |
| White Sturgeon have been described as opportunistic feeders, feeding on the bottom with their long snouts and using their barbels to detect food. |
