Tidal Flat, Figure 8 Biology of some tidal flats of estuaries in southeastern Australia. (a) Polychaete workings of sediment (low-relief
conical mounds) and burrows on a low tidal flat, Tasmania. (b) Fish and stingray feeding excavations on a rippled low tidal sandy flat,
Tasmania. (c) Slightly muddy sand low tidal flat with shallow pools, Tasmania; swarm of soldier crabs on the surface. (d) Swarm of
soldier crabs on low tidal flat and white-faced heron (Egretta novaehollandiae) feeding on the crabs, Botany Bay, southeastern
Australia.

types of biota commensurate with substrate type and tidal level setting (modified after Semeniuk et al., 1978).
