This is my favourite bend in the Lane Cove River… the rich colours and symmetry of reflection as the light hits it early in the morning

The replacement of complex natural shorelines with armoured, vertical, featureless seawalls like this one has big implications for the intertidal communities that can live here. Whilst such structures are less expensive, they provide little opportunity for marine organisms to settle and grow, and do little to dissipate the energy of waves and floods. Darling Harbour, Sydney.

ICOLLs (Intermittently Closed and Open Lagoons and Lakes) are a feature of Australia’s coastline. They open up when rainfall is sufficient to scour the entrance, converting from a closed brackish lagoon to a salt water estuary. In times of drought, like now, they are often closed, unless local councils open them up with diggers like this one at Narrabeen

B. auratum is an Australian endemic that lives in the intertidal zone. The sexes are separate, with spawning occurring in winter and spring. These two aren’t shy – they have climbed to a nice high vantage point on the root of a mangrove on the Lane Cove River
