Iconic marine species that are evident in the Filfla documentary
Amberjacks have a field day in the waters around Filfla, fully exploiting the strong currents which dominate the waters around the islet and which allows them to capitalise on their weapon of choice: speed. Their streamlined, bullet-shaped bodies enable these pelagic, open-water fish to cut through the water with amazing speed. Unfortunately, the popularity of this game fish, carrying its trademark dark bands across the head, has resulted in its decimation through commercial and sport fishing.
Scorpion fish
Camouflage is not restricted to terrestrial animals, but is also widespread among marine ones. The scorpion fish, for instance, has mastered such a skill and is a fitting candidate for the title of “chameleon of the sea”. For instance, you would be forgiven for thinking that this is yet another alga swaying with the currents, but care to look closer, and a formidable and patient predator on the prowl emerges. Relying on stealth and deceit to catch its prey, the scorpion fish has evolved body appendages which sway with the currents, rather than being stiff, so as to further con hapless passersby.
Common stingray
The stingray’s cartilage is excellent for the undulating movements that are so characteristic of these graceful creatures. But not all rays rely on undulating movements. In fact, some seem to fly through the water, like this common eagle ray, whose lateral triangular wings are more pointed than those in the stingray, while its tail is decidedly longer. Stinging barbs can be added to such a tail with age, with this one sporting two bards on its tail for an expanded arsenal.
Eagle ray
The common eagle ray deserves its title not just for the shape of its wings but also for its beak. This individual happens to be a male by virtue of its two sex organs, known as claspers, which are basically extensions of its pelvic fins. While many shark species have to be constantly on the move just to breathe, rays and skates can afford to rest as much as they are active by virtue of two open- ings, known as spiracles, located behind the eyes that allow them to pump water through the gills.
European spiny lobster
The European spiny lobster is found in the eastern Atlantic Ocean, from southern Norway to Morocco and the Azores and in the Mediterranean Sea, except its eastern extremes. It lives on rocky exposed coasts below the intertidal zone, mainly at depths of 20 to 70 metres. It is easily distinguishable by its heavy antennae, which are longer than the rest of its body. Unfortunately, since the lobster is considered to be a delicacy, this species is constantly exploited in the Mediterranean and has retreated to deeper waters.
