Abalone have a rasping tongue, called a radula, to graze on algae, though they catch most food by raising their shell and clamping down on algae as it floats by. As a result, they are therefore found in greatest numbers on those parts of a reef where bits of broken-off algae tend to collect.

How can you tell how old abalone is?
The age of abalone is determined by cutting the shell through the cone, staining it, and counting the number of rings through a microscope – a boring and time-consuming task. Other measurements, which are easier to obtain, may be used to predict the age. These variables were measured on 4177 abalones.
What are the holes in an abalone shell?
The shell has a set of characteristic holes, which the perlemoen uses to vent water through its gills. The gill chamber, a part of the body near these holes, is used to eject all of the abalone's waste into the water. Between the foot and shell, the abalone's organs are arranged in a circular pattern.
