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.

Male Ember Parrot fish

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.

Semi-Juvenile Ember Parrot Fish

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.

Juvenile Ember Parrot Fish

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.

Dived Up Publications announces the release of The Diver and the Cookby Lasse Spang Olsen

Published

The Diver and the Cook

A ship lost. No survivors. A grim recovery mission begins, pushing a team of commercial divers well beyond their comfort zone.

Braving treacherous conditions, saturation diver Nico van Heerden single-handedly combs the cramped, debris-strewn, zero-visibility Jascon 4 shipwreck searching for any sign of the lost crew.

Then, in a scene akin to a horror movie, while exploring a small, isolated compartment, Nico feels a tap on his shoulder. Could someone have survived underwater for over sixty hours?

The Diver & the Cook is the incredible true story of a seemingly impossible underwater rescue. With first-hand accounts, authentic images and detailed reconstructions, author and documentary maker Lasse Spang Olsen brings this gripping tale to life. The book is the result of over four years of work, including intensive interviews, access to previously unknown material, and deep study of conversations and film recorded during the actual incident.

Witness the unwavering determination of the human spirit as Jascon 4 galley chef, Harrison Okene, fights for survival after his ship goes down. Meanwhile, rookie saturation diver Nico van Heerden faces a daunting challenge: spearheading the rescue mission in a perilous underwater environment. With time running out, what rules must the dive team break to save Harrison before it’s too late?

An unprecedented operation, this story provides a unique perspective on the dangers and challenges faced by divers, showing the importance of teamwork and communication in high-risk situations. An incredible survival story against all odds, with an equally surprising aftermath.

Quote from the author, documentary-maker Lasse Spang Olsen:

“There are a whole lot of different versions of this story out there. But I believe that by speaking directly to the key people involved, creating meticulous reconstructions and doing original research we have dug much deeper and got far closer to the truth about the rescue and the sinking than anyone has ever managed to before.”

About the author

Author and veteran filmmaker Lasse Spang Olsen – in a 40+ year career – has participated in stunts and FX on over 600 films, directed eleven features and filmed extensively underwater. He’s led expeditions uncovering historical mysteries like the Flying Enterprise wreck and documented adventures worldwide. He’s also a producer and lecturer. Originally published in Denmark as Dykkeren of Kokken (February 2024), this is his fourth book.

The Diver and the Cook (ISBN 978-1-909455-61-0) is released on 12 November 2024 in paperback and ebook. It is available via online retailers, bookstores, from DivedUp.com and to the dive trade via Nautilus UK.
