I love the translucent arms on this animal at Shiprock – and if you zoom in you can see the tiny chromatophores that allow it to change colour

This yellow colonial ascidian is smothering large sections of the wall at Shiprock aquatic reserve – is it the invasive Didemnum vexillum?

Climate fail Australia! 4 C by 2100 #marineexplorer by John Turnbull

Scientists have modelled the likely rise in global temperatures if Australia maintains its current climate policy settings – and the answer is 4 C by 2100. That’s on par with the USA, and only slightly better than the worst large countries, China, Russia and Canada, with settings heading for 5 C. What does this look like? Inundation of coastal cities, worldwide food security issues and substantial loss of biodiversity for a start. www.theguardian.com/environment/2018/nov/16/climate-chang…

It’s breeding time for one spot pullers, and they seem to spend a lot of time chasing each other about. This mob was chasing a red scorpionfish which ducked down under a boulder to escape them. Shelly beach, Manly

Artificial lights, like these flooding Sydney Harbour, can change fish behaviour and therefore impact on marine communities.

The pink trombone of this common tubeworm is in fact the operculum (trapdoor) which is pulled close when the animal withdraws into its tube. Bare Island
