Maloudja beach is one of the large of the island with its beautiful beaches and a large coral reef of the island
It is rich with typical fishes
There are some species far from the beach but near the coral reef and lagoon area, such as pelagic
The pelagic thresher (Alopias pelagicus) is a species of thresher shark, family Alopiidae; this group of sharks is characterized by the greatly elongated upper lobes of their caudal fins.
The pelagic thresher occurs in the tropical and subtropical waters of the Indian and Pacific Oceans, usually far from shore, but occasionally entering coastal habitats.
It is often confused with the common thresher, even in professional publications, but can be distinguished by the dark, rather than white, color over the bases of its pectoral fins. The smallest of the three thresher species, the pelagic thresher typically measures 3 m (10 ft) long.
The diet of the pelagic thresher consists mainly of small midwater fishes, which are stunned with whip-like strikes of its tail. Along with all other mackerel sharks, the pelagic thresher exhibits ovoviviparity and usually gives birth to litters of two.
The developing embryos are oophagous, feeding on unfertilized eggs produced by the mother. The young are born unusually large, up to 43% the length of the mother. Pelagic threshers are valued by commercial fisheries for their meat, skin, liver oil, and fins, and are also pursued by sport fishers. The International Union for Conservation of Nature assessed this species as endangered in 2019.
Little information is available on the feeding ecology of the pelagic thresher. Its very slender tail and fine dentition suggest an exclusive diet of small, pelagic prey.
Analysis of stomach contents reveals that pelagic threshers feed mainly on barracudinas, lightfishes, and escolars, all inhabitants of the mesopelagic zone. Therefore, little competition occurs between the pelagic thresher and other large oceanic piscivores such as billfishes, tunas, and dolphinfishes, which tend to feed near the surface.
As in other threshers, pelagic threshers may swim in circles to drive schooling prey into a compact mass, before striking them sharply with the upper lobe of their tails to stun them. Because of this behavior, pelagic threshers are often hooked on longlines by their tails.
