Biology Abundance of these holothurians has increased dramatically - from around 4 individuals per ha (based on photographs) in the early 1990s to almost 6500 individuals per ha in the late 1990s (Bett et al., 2001). This phenomenon became known as the "Amperima event" (Billet et al, 2001). [details]
