The largest tank of the Cala Gonone's Aquarium contains over 350000 liters of water . For this reason, it hosts larger species such as common smooth-hounds, greater Amberjacks, dentex, glit-head seabrams, meagre, and grouper.
Common smooth-hound Mustelus mustelus
This species of hound shark is found in the Atlantic Ocean and in the Mediterranean Sea. It lives in depths ranging from 5 to 600 meters and it does not pose a threat to human beings. It commonly grows up to 2 metres long and can live up to 24 years! The common smooth-hound has a grey-brown back and a white underbelly. It is a predator and feeds mainly on shellfish, cephalopods (octopus, squid, cuttlefish, etc…), and small fish found on the seabed. According to the IUCN’s red list, it is considered an endangered species and at risk for extinction due to overfishing. At our aquarium, these fish are fed once a day, at the same time and in the same place by way of long pliers.
Greater Amberjack Seriola dumerili
The species gets its name from its bottle shape. In fact, the diminutive of the Latin word “seriola”, “seria” means bottle. It is a circum-global pelagic species and particularly gregarious in the juvenile phase of its life. It lives in depths of 10 to 70 metres. The Greater amberjack can reach a length of 2 metres and can weigh as much as 90 kilograms. It has an oval body shape which is somewhat compressed laterally. The silver colour is ventrally in adults and yellow-green in juveniles with dark body bands. The first phases of this species are, to say the least, explosive: individuals born in spring reach weights of 800 grams and 40 cm in length, in the span of one year. By the time they are 4 years old, they have usually tripled in length (93 to 106 cm).
Dusky Grouper Epinephelus marginatus
The Dusky Grouper grows up to 120 centimetres long and can weigh as much as 40 kilograms. It is curious, solitary and particularly sedentary. This species usually chooses one or more dens inside caves. Groupers are long-living fish and can live up to 40 years!
