From Dust Till Dawn
Sunrise with Amed Scuba |
Having bagged the first image of the
day we move to the Liberty wreck in calm chrystal clear water and
spots a group of huge bumbhead parotfishes lazily waiting for the
rest of their group to move to their food places. Suddenly they move
together away from thir night time hiding place in the Liberty shipwreck and the fishes are prepaired for another day of grazing the
algae from the reefs and peered out to check the horizon for a tasty
patch of food. Parrotfishes are a
group of about 90 species
traditionally regarded as a family (Scaridae), but now often
considered a subfamily (Scarinae) of the wrasses. They are found in
relatively shallow tropical and subtropical oceans throughout the
world, displaying their largest species richness in the Indo
Pacific.They play a significant role in bioerosion. Parrotfish are
named for their dention, which also is distinct from that of other
labrids. Their numerous teeth are arranged in a tightly packed mosaic
on the external surface of their jaw bones, forming a parrot-like
beak with which they rasp algae from coral and other rocky substrates
(which contributes to the process of bioerosion).
Maximum sizes vary within the
family, with the majority of species reaching 30–50cm in length.
However the green bumphead parrotfish can reach up to 1.3m. Although
they are considered to be herbivores, parrotfish eat a wide variety
of reef organisms, and they are not necessarily vegetarian. Species
such as the green humbhead parrotfish (Bolbometopon muricatum)Green Humbhead Parrotfish (Bolbometopon muricatum), Amed Scuba |
include coral in their diets. Their feeding activity is important for the production and distribution of coral sands in the reef biome, and can prevent algae from choking coral. One parrotfish can produce 90kg of sand each year. (Wikipedia )
As the sun rises higher in the sky the bumbheads have disapeared and another hunter of the nightfind his niche. A moray eel retreats into his burrow to awit a darker moment and recommence his hunting. The largest in terms of total mass is the giant moray (Gymnothorax javanicus), which reaches 3m in length and 30kg in weight. It is so amazing to watch this giant swimming around the wreck of the Liberty.
As the sun crept over the reef crest, we came across a school of adolescent golden batfish cruising the wall. In this species, the juvenile is very similar to the adult form. This isn’t the case for some other species of batfish where the juvenile Pinnate mimics a toxic flatworm, the juvenile Batavia is black and white striped to hide among feather stars and the juvenile Circular, which is an almost exact replica of a leaf.

Predatiors lurking, already awaiting
thir breakfast, little frogfishes are difficult to spot, completely
disguised as a part of his surroundings. It lives in perfect
camouflage. Frogfish coloration varies from species to species, and
even whithin the same species.
Textures range from smooth velvety skin
to algea or sponge covered warts, and even spots that look just like
those of sponge.
With the creation of nudibranchs,
nature expresses its wildest indulgence of colors and forms. There
are
more than 3000 described species of nudibranch, with new ones
being identified almost every day. Their size ranges from just a few
millimeters to around 300mm. They can be found in all the oceans of
the world and within most habitats, but are more abundant in shallow,
tropical waters such as Bali. Even the egg ribbons can come in an
amazing array of size, shapes, colour and design, depending on
species, and are usually laid on or near food sources.
