Some barnacles can feed in two
modes. In energetic currents, they use their cirri as passive nets. In
calm conditions, they feed actively, as shown above.

Larval transport is dependent on (a) larval behavior and (b) physical
transport. Larval transport is dependent on larval behavior in that
specific behaviors are required to exploit specific transporting or
concentrating mechanisms. Larval behavior is also important in
determining settlement rate.
Our currents studies on larval behavior include:
Dependency of settlement rate
on the amount of suitable substrate.
- Dependency of larval transport by internal bores and other gravity
currents on larval behavior.
- An experimental project on the swimming capabilities of invertebrate
larvae in convergent currents. (With other colleagues.)
- Effects of freezing on settlement behavior. This was unexpected! see
project description here.
