title: Characterization of the Sounds Produced by Temperate and Tropical Sea Urchins During Feeding (Diadematidae and Echinometridae).
abstract: Despite the abundance and ecological importance of sea urchins in eastern Australia, it is not known how they may contribute to ambient noise. The sounds of feeding of two temperate and two tropical species were recorded in captivity. Most sound was produced between 2.3 and 9.2 kHz, but there were differences between species and substrate types.
