Description

On dorsal lip and head of a smooth toadfish. This male Louse was seen moving positions quite actively and frequently during the few minutes I watched, but it was adept at staying on the head end of this one individual fish despite the fish appearing to be trying to get rid of it by frequently burying almost completely in the sand and moving around while doing so. We often see this species of parasitic Louse attached firmly to various species of inshore demersal fish but I don't often see them firmly attached to any toadfish. Occasionally they are attached to juvenile (smooth et al eg prickly) toadfish but rarely adults. Perhaps the tetrodotoxin on the skin of most toadfish makes the adults uncomfortable hosts for the Louse. Toadfish might be temporary or 'last resort ' hosts when there are no other fish species available at a particular location?

Moonlighter (Tilodon sexfasciatus)

Description

Image 1 cropped from image 2.This older juvenile moonlighter appears to be a host cleaner for some other reef fish in the main frame including bluethroat wrasses (females),silver drummer and possibly sea sweep but I don't have photos proving the host client interactions from this snorkel.
Certainly the moonlighter was actively patrolling the small ledge and the other reef fish, as potential clients, kept returning to the ledge as soon as possible whenever I backed off. I saw some drummer and a magpie perch adopt obvious client poses. As usual in my experience in such cases one can't exclude the presence of several other species of host, especially western cleaner Clingfish and Rockpool shrimps, merely because one hasn't been able to see them under the ledge. Indeed it is usual for several host species to cooperate at an active cleaning station.

Description

I think.
Image 3 gives scale by including a young Blackspotted Wrasse. This true stony colony-forming (but not reef-forming)coral is on inner face of the platform reef directly in line with the end of the jetty.
There are a few smaller colonies of this species only metres southward(and doubtless many more at various points on inner and outer faces of this long-shore platform reef,north and south of jetty.)

Description

Various views of the dominant seagrass alongside the inshore aspect of this jetty.
The last photo was taken immediately prior entry for this shallow snorkel at low tide and all other images are from within the area shown.
(Depth of 1.2 metres applies for image 1, but maximum depth for some of the other seagrass images was about 2.5 metres).

FWIW I note the heavy epiphyte load of one of the opportunistic brown or red algae (such as Hincksia, Gracilaria, Asparagopsis,Plocamium, but I don't know what the particular genus is, in this case).
This appears to be a concern(anthropogenic nutrient levels) given the bay's perennial increasingly heavy recreational fishing activity (boats jetties and shore),rapidly increasing residential subdivision (with associated waste water management challenges and increased stormwater runoff) and the fact that the water temperature was only about 16 degrees (not unusual for early Spring ).
