High Tide 1:40 pm
Red-billed gulls breeding and Reef heron fishing on Passage Rock.
75m transect
35minutes
Current low
Vis 2m
Depth 5m
Substrate: Rocks and sand => Gravel => Mud
Epibenthic fauna dominated by Mediterranean fanworm and pleated tunicate barring a nice patch of White-striped anemone.
Mud was soft and deep, I put my hand in seven times. Green lipped mussel shell four times at 25cm, scallop twice at 10-15cm, one plunge found no shell.
Nice to find a fisher parked by my boat when I surfaced to check I wasn't fishing in the marine reserve :D
This ID is for the abundant round shell. The shells were exposed by another animal digging on the seafloor.
I could see yellow on its beak and legs
Breeding, two juveniles seen, other breeding on rocks not investigated but a WFT was also agitated by my presence
