Diving the Indian Ocean Reefs
Parrot Fish… Did You Know?
The most colourful fish you’ll notice at on your first Indian Ocean dive may well be the spectacular turquoise-green, blue and pink male Ember Parrot Fish, (Scarus Riboviolaceus) which is by far the most common of the parrot fishes seen on our Indian Ocean reefs.
The males are gorgeous, and completely different from the juveniles and females.
Parrot fishes start life in the hard stag-horn corals and branching finger corals as insignificant little striped fish. The juvenile and semi-juvenile just look like any other small striped fish, with only the distinctive beak-like mouth to distinguish them from any other very young fish species.
They grow into nondescript rust grey and brown females who inconspicuously cruise across the reef crunching on the hard corals. As young fish they travel in groups, but as they get older and bigger, they feed alone.
As they grow their colouring develops, and they become more spectacular, with bigger bodies, richer fin outlines and the drab brown begins to bloom with new colour. There can only be one male in any area. One day, when the dominant male in an area dies, the largest female loses her mind and her drab colouring and turns into a peacock-coloured randy male who chases the drab brown females across the reef, mating indiscriminately.
As the male reaches terminal stage, his colouring begins to fade and he dies. We have seen huge terminal male Ember Parrot Fish in the sea-grass beds South of Stringer Reef at Sodwana Bay.
On the shallower reefs, you may be lucky enough to see the rare and beautiful Bridle Parrot (Scarus Frenatus) fish, and if you look carefully at the markings, you may be able to distinguish a Tricolour Parrot ( Scarus Tricolor) fish from a Christmas or Starry-Eyed (Calotomus carolinus) parrot fish, or spot an occasional Blue Moon Parrot ( Chlorurus Atrirunula) fish.
We have seen Blue Barred Parrot ( Scarus Ghobban) fish, and in deeper water, around and occasionally on the staghorn corals on the edge of 2 Mile Sodwana Bay, you might be lucky enough to see the richly coloured dark blue velvet of a female Hump Head Parrot ( Chlorurus Cyanascens) fish, or the ornate green and blue of the male Hump Head.
The Parrot fish family lives on the polyps and algae that make up the hard corals, and they graze continually. Living on hard corals is enormously time consuming, as the nutritious part of the polyp is minute. The parrot fishes are at least partly responsible for containing the growth of finger corals and branching corals.
They excrete a fine white powder which in part makes up most of the world’s powder white coral sand beaches – bio-sand production perhaps?
In Mauritius parrot fish are a delicacy, and the result has been a massive depletion in the variety of species near the main Island.
Under-age sex is the norm among the parrot fish here, with very juvenile females taking on the male role when they are too young. They are breeding a dwarf ember parrot fish, which has become quite prolific as it is too small to eat. I have often seen 8 inch little ember males haring after distinctly under-age females with lustful eyes.
On the outer Islands, the parrot fishes grow to normal size, as the subsistence fishermen cannot take their little boats out to the distant Islands. As the numbers of subsistence fishermen drops with the increase of wealth among the Mauritian population on the Island, perhaps we’ll see the exquisite parrot fish replaced on local menus by chicken.

Shark Trust launches Oceanic 31 Shark Art Auction
After a two-year tour of UK art galleries, community spaces and aquariums, the Shark Trust’s acclaimed Oceanic31 exhibition takes its final bow at the Royal Geographical Society later this month. And the unique collection of artwork, depicting 31 species of oceanic sharks and rays, donated by 31 artists, is now open for bids from art lovers and shark enthusiasts. The online auction, launched today, will close on the 7th December at 8pm (BST). The money raised will support the Shark Trust Oceanics Programme.
People can now bid on 27 of the artworks by visiting this website:
https://superstars-auctions.com/sharktrustauction
It is a chance to own a beautiful piece of original art and to support the Shark Trust. The timing of the auction also means that these would make a very special Christmas gift for any shark-lover.
The diversity of pieces mirrors that of the sharks and rays they represent. You can bid on paintings, digital creations, sculptures, mixed media and more. You can pick your favourite artist or species of shark. Or you can select the perfect artwork to make a statement in your home or office. Whichever you choose, you will be supporting the work to protect these amazing animals.
One of the pieces of art has been selected to be auctioned live by Steve Backshall at the For the Love of Sharks event at the Royal Geographical Society in London on the 29th November. In addition to this, two further pieces will be raffled at this event, giving people a chance to win an incredible piece of shark art. For the Love of Sharks is the Shark Trust’s flagship evening. A night to celebrate sharks. Steve Backshall is the headline speaker at this event that will see other prominent shark advocates join him on stage.
Tickets for the event can be snapped up here:

Paul Cox, Shark Trust CEO, Said “This exhibition has given us the opportunity to reach out to a new audience.

Meet Steve Backshall in the Bite-Back Prize Draw
Until 28 November, prizes worth a massive £10,000 – including experiences, products and tuition – feature in a line-up of items that can be won for £5 in an online prize draw to celebrate Bite-Back Shark & Marine Conservation’s 20th anniversary and help generate crucial funds for the future.
Top of the list of prizes is the chance to spend time with adventurer and wildlife expert Steve Backshall, a workout session with Nat Geo star Aldo Kane, a kayaking trip alongside white-water expert and diver Sal Montgomery and a Zoom call with ‘shark whisperer’ Cristina Zenato.
On top of that, some of the most admired companies in the diving and scuba industry have been quick to support the charity with fabulous prizes that make the £5 ticket price worth more than just a flutter.
Master Liveaboards, BSAC, Midlands Diving Chamber, Go Freediving and Blue Shark Snorkel have all generously donated experience prizes, while celebrated photographer Alex Mustard has donated a print and artists Scott Gleed and Olivier Leger have donated a sculpture and illustration to help boost the fundraising pot.
Fourth Element has donated Ocean Positive gear and LA watch company Nodus has gifted the charity a stunning dive watch. For land lovers, the charity has included a five star London hotel stay at Bankside Hotel plus a family visit to Longleat Safari Park in the roster of prizes.
Campaign director for Bite-Back, Graham Buckingham, said: “We’ve been overwhelmed with support from companies and individuals that we truly admire and who have supported us on our 20 year journey and we’re truly grateful to them all. While we feel incredibly proud of our achievements over the past two decades – and we are super excited about the next chapter – this prize draw isn’t a vanity project. It represents a real lifeline to our work and important advancements in the global protection of sharks. So we hope divers, dive clubs and even bargain hunters grab some tickets to make this a massive success.”
The charity hopes that the prize draw will generate crucial funds to launch a brand new, ground-breaking, campaign to enrol the public and increase support for the protection of sharks around the world.
