The Gaadhoo-Hithadhoo sea on the southern edge of Hahdhunmathi, lying between Gaadhoo and Hithadhoo has plenty of marine life species in it. It has been recorded that reef fish lay eggs here to populate. Some significant species that have been observed here, which are protected in the Maldives, are Mobula Alfredi/ Reef Manta Ray (En’madi), Napolean Wrasse, Cheilinus undulates (Maahulhun’bu Lan’daa) and two species of turtles. These include Chelonia mydas/ Green Turtle (Velaa) and Eretmochelys imbricate/ Hawksbill turtles (Kahan’bu). Similarly, multiple species of sharks, whale sharks (fehurihi), and rays are also recorded to be found in this area. As these species are internationally declared as endangered, it is of the utmost importance that this area is protected to maintain their population levels.
