White Mermaid's Wine Glass

Aspect: At first sight looks like pale green to white monochrome daisy, but is in fact composed of a radially fluted disc on a thin stalk.
Population: Not widespread.
Notable feature: Very fragile. Solitary and therefore difficult to spot.
Environment: Grows in sheltered areas, amidst other protective algae or weeds.
Behaviour: .

Who are we?

Who are we?

 

Eric  Franjack H 30 Dec 2009 P1000857Daniel at Jardin Corail b 19 Dec 2008 IMG 0143The authors of this site are father (Eric H. Biass) and son (Daniel H. Biass) with more than two and a half decades of diving experience behind their belts. While initially underwater photography was purely intended as a graphical souvenir-gathering exercise, the discipline very rapidly took a sharp scientific stance, particularly with Daniel’s biology studies in the early 2000s that eventually culminated in a PhD in Sciences.

Saucer Blade Alga

Aspect: Green leaves (blades) shaped like small, thin ping-pong rackets on variable length brownish stems. Blade surface looks like felt.
Population: Common.
Notable feature: Tend to grow in line because the stems are attached to a common root running under the sand.
Environment: Shallow sandy bottoms.
Behaviour: .

Welcome to ::divepix::

 

Franjack 29 Dec 2010 P1010953The aim pursued by this site is to provide not only a photographic illustration of the animal and vegetal creatures that populate the waters surrounding Ilêts Pigeon (a.k.a Reserve Cousteau) in Guadeloupe (Gwadloup in Creole), but also a user-friendly pedagogical tool for all, beginners and connoisseurs alike.
The site is bilingual English and French, but wherever possible species are also being given their local Creole designation.

 

As it turned out

 

Illustrating a decade of regular diving on the west coast and south of Basse-Terre (namely Saintes and Sec-Pâté), these photos turned out to have a survey value with the authors’ diving logbook notes pointing to demographic changes, which more often than not are cyclical.

On a more pleasant note, where spotting a distant turtle commanded celebrations ten years ago, strict fishing restrictions have borne fruit and virtually no dive can be accomplished nowadays without the company at one time or another of these prehistory-age carapace-bearing reptiles.

Swiss Cheese Alga

Aspect: Brown entanglement of loosely intertwined fibres reminiscent of a decaying rug.
Population: Common.
Notable feature: May sometimes be seen rolling on the sea bed, pushed by currents.
Environment: Relatively shallow waters.
Behaviour: .

Tidal Spray Crab

Aspect: Overall light brown/yelowish appearance, closer look reveal a grey-yellow carapace peppered with small dark spots, centre has mottled red and brown areas. Legs are the same colour with larger brown stains, while their outer segments are brown banded. Eyes are yellow-pale green and close to the carapace.
Population: Common.
Notable feature: Deep cleavage in the middle of the "forehead" area of the carapace. Tip of the short red claws are white.
Environment: Tidal waters.
Behaviour: Weary.

Watercress Alga

Aspect: Small green, irregularly rounded leaves densely attached to short branching stems.
Population: Common.
Notable feature: .
Environment: Usually found in shallow, waters, between rocks.
Behaviour: .

French Angelfish

Aspect: Adult features white-grey mouth, blue head with yellow eye-brows, followed by dark body with yellow-edged scales. Young individuals boast overall dark body with three heavy yellow vertical bars that fade away at intermediate stage as grey snout and blue head develop more strongly. Even younger individuals have bright blue pectoral and anal fin tips.
Population: Regularly abundant.
Notable feature: Often live in pairs.
Environment: Usually found at depths of between 20 and 40 metres, the latter particularly in or around wrecks.
Behaviour: Will usually tolerate a diver's quiet presence, even totally ignoring his presence when a nearby turtle is busy shredding a sponge and throwing nourishing debris around.

Sargassum Seaweed

Aspect: Ochre serrated leaves attached to a dark brown multiple-branch central stem. More usually seen floating on the surface of the sea, sometimes floating midwater on their slow ascension to the surface.
Population: Normally not abundant in Guadeloupe, except in the mangrove areas. Invasive waves of such algae have however started to reach the islands, drifting northwards from the southern areas of the Caribbean.
Notable feature: Each branch carry a number of light ochre berries that are in fact thin-skinned gas-filled bulbs that enable the plant to remain erect and thus facilitate photosythesis, but they also eventually causes it reach the surface.
Environment: The plant actually grows under the sea surface. The recent outbreak of large floating mats in the Carribean is attributed to a combination of two main factors, namely the over-use of agricultural fertilisers in areas of Central and South American mainland promoting their growth, and a change of sea currents resulting from the climatic change.

Longsnout Butterflyfish

Aspect: Almost looks like a cartoon character with white lower body fading into a bright yellow upper body topped by almost dark dorsal fin. Tail and pectoral fins are transparent
Population: Regularly abundant.
Notable feature: Unrealistically long snout that earned it its "Pinokio" designation in local creole.
Environment: Usually found in shallow, quiet waters
Behaviour: Very shy, always turning around stones and boulders, difficult to photograph.
