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.
It was eating oysters
Four of four shells dug up at 25cm depth
One of two shells dug up at 10cm deep
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
