10 – Warty Oreo – 140 years
Warty oreos live in the waters of continental slopes, and they form in large schools over rough terrain. Young warty oreos are pelagic and reside in shallow waters of the oceans – less than a kilometer in depth. They eat other fish, as well as cephalopods and shrimp. The eggs and larvae of warty oreos live on or near the surface of the sea.
9 – Orange Roughy – 149 years
A deep-sea fish also known as the “slimehead,” orange roughy grows slowly and reproduces late in life. These traits make it especially vulnerable to overfishing.
8 – Aldabra Giant Tortoise – 152 years
The Aldabra giant tortoise lives on the remote Aldabra atoll, one of the Seychelles group of islands in the Indian Ocean.
7 – Lake Sturgeon – 152 years
6 – Shortraker Rockfish – 157 years
5 – Galapagos Tortoise – 177 years
4 – Red Sea Urchin – 200 years
The small, spiny creature can last for more than 200 years with few signs of age-related disease, a US research team from Oregon and California has found. The animal, which grows to more than 15 cm across, grazes on marine plants and uses its spines to deter predators.
3 – Rougheye Rockfish – 205 years
The rougheye rockfish (Sebastes aleutianus) are probably among the longest-lived marine fishes on Earth. The name aleutianus refers to the Aleutian Islands, where this species was first discovered. The rougheye is also known as the blackthroat or blacktip rockfish in the fishing industry. The name rougheye refers to the 2-10 spines that are common along the lower rim of their eyes, though some have been known not to have these spines. This absence can add to the difficulty of identifying the rougheye from the shortraker rockfish, which have one or no spines. The rougheye is also identified by appearing pink, tan, or brownish with loose patches of brown or bronze when viewed underwater. A darker blotch usually appears on the rear of the operculum, and the posterior area of the lateral line is often pinkish in color. These fish are bright red or pink with black or gray patches after capture, which distinguishes them from the orange-pink or bright reddish-orange color of the shortraker. Another difference is that the rougheye has long, thin gill rakers on the first arch, while the shortraker’s are short with knobby ends. These fish usually grow to 32 in. (80 cm), and have been reported as large as 38 in. (97 cm). Males and females are thought to be of similar lengths at any given age.
2 – Bowhead Whale – 211 years
People also know this big whale as Greenland right whale or Arctic whale. Bowhead whales got its name from its high, arched jaw that resembles a bow. Bowhead life in the Arctic Ocean and adjacent seas. They spend most of the summer in relatively ice-free waters of the seas bordering the Arctic Ocean. They are associated with sea ice throughout the year. Bowhead whales are circumpolar, ranging in very high latitudes in the northern hemisphere. They spend the winter in connection with the southern boundary of the ice and move north as the sea ice breaks and retreats in the spring.
1 – Ocean Quahog – 400 years
The Ocean quahog is a typical cockle-shaped bivalve, and the two halves of its hinged, rounded shell are thick, glossy and dark brown in colour. It is a long-lived animal and is quite large for its kind, growing up to 13cm across. Ocean quahogs can be found from just below the low water level to depths of about 500m. They live buried in sand and muddy sand, often with their shells entirely hidden and just a small tube extending up to the surface of the seabed. The tube is a siphon that keeps water flowing across the animal, so that it can breathe, capture food, and expel waste.
