Out on A Swim

My Out on A Swim blog is rated in the Top 20 Coral Reef Blogs in the world.

It serves as a record of what has caught my eye when ‘out on a swim’ in the lagoons of Norfolk Island, as well as providing some short stories about the characters under the waves.

How did the snowflake moray get its proper (scientific) name Echidna nebulosa, and what does it have to do with Australia’s famous and iconic marsupial, the echidna? Read on to find out more …

Feisty zingers! Focus on the 'brain' coral, Paragoniastrea Australensis
Dec 1, 2024

If corals had characters, then the Paragoniastrea australensis would be described as feisty, or even downright aggressive when it comes to asserting itself over its neighbours. They are also rather colourful.

Then and now – shifting baseline syndrome laid bare
Nov 20, 2024

If disease were spreading through our native forests, if our trees were developing strange growths that hollowed them out, making them brittle in the face of each passing storm, would five years have slid by with the problem worsening by the day? That is exactly what is happening on Norfolk Island’s reef. Slowly, insidiously, it is dying and turning to slime.

Gorgeous, boring brown, Montipora corals! These beautiful coral colonies (and remember, these consist of loads of tiny little animals, which work together to create these amazing shapes) are one of our key reef-building corals. There are around 85 known species belonging to the Montipora genus.

CSIRO are on Norfolk Island this week to present the findings of their report into water quality. As our Administrator, George Plant, says: ‘What the data shows us is that the quality of ground and surface water entering Emily and Slaughter Bays often contains high levels of contamination ... The health of the Emily and Slaughter Bay reef will continue to decline if we do not improve water quality.’

One of the first corals to catch my eye when I set out with my new camera in January 2020 was this stunning boulder coral that sits off the Salt House in Emily Bay. Regular swimmers would all be aware of its presence, but not many would realise that it is quite possibly an as-yet undescribed species of coral, which for the moment is known as Lobophyllia recta sensu Veron.

'Barometers of life' – National Threatened Species Day
Sep 7, 2024

Today's National Threatened Species Day post discusses the conundrum of Australia's threatened species list and the IUCN Red List as they relate to vulnerable and threatened species here on Norfolk Island in the Marine Park. How, for example, do we offer protections to something that hasn't been formally identified yet, let alone listed as threatened?

Groundhog Day in Emily Bay
Aug 9, 2024

Four years ago, we had what amounted to nothing short of an environmental catastrophe in our lagoons. In the intervening years we have had numerous reports commissioned and delivered, and I have written plenty of blog posts about our poor water quality. Three weeks ago, on 20 July 2024, it all happened again. In this post, I explain exactly what occurred. Groundhog Day in Emily Bay, Norfolk Island.

Ageing colourfully. This guy!
Jul 23, 2024

I’ve been photographing this guy, a green moon wrasse, since 2020, when he was a young adult just transitioning from being a female to a male. Green moon wrasse are said to live five to seven years in the wild, which means that our lovely old friend here could well be classified as an elder. This post is dedicated to this cheeky and inquisitive fish, the boss!

While you were sleeping ...

This massive and incredibly slow-growing Paragoniastrea australensis sits in Emily Bay on Norfolk Island and is one of our most recognisable bommies. While all looks reasonably calm during the day, at night, while you are sleeping, the surface of the coral colony seethes with millions of tiny tentacles busily reaching out to find food, while others aggressively ward off opportunistic interlopers.
