Bait Ball video at MTANSW Conference

We presented this video to members of the Marine Teachers Association of NSW at their annual conference in Narooma last Friday. We are pretty sure they are juvenile convict goby (Pholidichthys leucotaenia).

Teachers said a bait ball configuration is an excellent defence mechanism for small fish. It allows them to look like a much larger creature or object, and makes it harder for predators to target individuals to eat.
