Turtles and snake eels

September 28, 2021

Emily Bay never fails to lift my spirits. Today in my ‘Out on a Swim’ blog, I talk about our beautiful, elegant snake eels. We have at least three different species. I also saw my elusive spotfin squirrelfish, and our two resident green sea turtles snoozing next to each other. Naawww!

Banded, convict and spotted snake eels - know the difference

August 31, 2021

A beautiful banded snake eel, Leiuranus semicinctus, popped into view on Saturday. These gorgeous guys are docile and will dive head first into the sand if you get too close. Read on to discover how many types of snake eel we have in Norfolk Island’s lagoons.

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 and brown!

Oct 20, 2024

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.

Taking stock. Which way from here?

Oct 14, 2024

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.’

You may call this beauty 'Lobophyllia recta sensu Veron'

Sep 15, 2024

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 ...

Jul 10, 2024

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.

Gender transitioning in the birdnose wrasse

Jul 7, 2024

All birdnose wrasses are born female but will change to males if the conditions are right. Its appearance changes radically throughout is lifecycle, from when it is a juvenile, through to being a female and then finally to being a male (known as sexual metamorphosis, or sequential hermaphroditism). For about three weeks you can see that transition taking place in the sequence of photos in this blog.

One hundred year-old coral gone in less than one hundred days

May 27, 2024

Paragoniastrea australensis is an incredibly slow growing species of coral. The colony featured in this post is probably 100 years old. When disease took hold in January 2024, it was gone, dead, in less than 100 days. Now it is a skeleton overgrown with algae. The worst part of this sad story is that it is our fault it died.
