Perhaps aging is a natural process of life, but for our animal friends, this is absolutely an curse: those sick and elderly, slow animals most likely to be cuisine of the predators. For pampered pets and zoo animals enjoy protection. They can get more chance than that in the wild to survive, and thus to live much longer. Take a look at the world’s top 10 animals with long life, which is enough to make you a surprise! ! !
10.Lamellibranchia tube worms:
These gorgeous deep-sea creatures are tube worms. They live near vent of the carbohydrates in the sea. An animal with penis similar structure is likely to be the “missing link ” of two mystical branch of marine animals during their evolved process.
Scientists say it is called tubular worm of pterobranchia which is a transition branch during evolution process . It is well known that they can survive for 170 years, but many scientists believe that perhaps some of them have survived for more than 250 years.
9. The goddess of clams
These huge marine clams are belong to Mollusca Bivalvia marine invertebrates and its scientific name is Panopea generosa. They are native to the Puget Sound and is known to survive for at least 160 years.
They live along the North American Pacific coast, from southern Alaska to Baja California. Goddess clam is the largest diamond hole bivalves. The length of their shell is 180~230 mm (7~9 inches); pipes may extend to 1.3 meters (about 4 feet), which can not retracted into the shell; Total weight with the shell can up to 3.6 kilograms (8 pounds). They are delicious and edible, but they always habitat in the deep hole dug in hard. They are famous for its long “neck” or siphon, which can grow up to one meter long.
Turtles are considered as the vertebrates with the world’s longest life expectancy. Among them, a representative species of the longest life expectancy is Galapagos tortoise named Harriet. it died in a zoo in June 2006 due to heart failure, when it was 175 years old. Euphrates tortoises, named Adwaita, reportedly died at the age of 250 years.
Bowhead whale (also known as Arctic whale, Greenland right whale) is a marine mammal belonging Cetacea. When they grew up, the length of bowhead whale can reach up to 20 meters long (females larger than males). Its body is very heavy. Bowhead whale’s blubber is as thick as 70 centimeters, which can help keep out the cold. They would drilled their own breathing holes. Currently the oldest life of bowhead whales have at least 211 years. The name bowhead whales is from the huge and unique arcuate head.
The word “Antique” is usually used to describe an old man, but when it comes to a lizard, this word is also not exaggerated. Large lizard is the only known surviving reptile from the age of dinosaurs on our planet. Their number has been very scarce. However, due to continued global warming, these big lizards, known as “New Zealand’s living fossils”, are in danger of extinction. Currently there are two survived big lizard species. They are antique alive. They are also the longest living vertebrate on Earth, some of the lizard’s lifespan is between 100 years to 200 years.
5.Marine circle clam
Marine circle clam is a clam species which are used for commercial exploitation. Typical species are North Circular clams (Mercenaria mercenaria, also known as cherry clams, little neck clams, hard shell clams) and South round clams (M.campechiensis). North Circular clam is about 7.5~12.5 centimeters (3 to 5 inches) long; shell is white, dull, thick, round, and with a clear concentric pattern; They are distributed in the Gulf of St. Lawrence to the Gulf of Mexico along the intertidal zone.It is the most important edible clams along Atlantic coast. South round clam is about 7.5~15 centimeters long; shell is white, heavy and thick, distributed between the Chesapeake Bay to the West Indies in the vicinity of the intertidal zone.
Researchers have been put on the black shell of concentric circles or rings interpreted as the year mark, and is very similar to tree rings. Some collected sample has been estimated to have over 400 years of life.
Koi carp is an ornamental domesticated fish. Koi (Cryprinus carpiod) is belong carp (Cyprinidae) in biology, carp species is the largest one of all fish families, with more than 1400 kinds of species.
It is popular in today’s world and is a high-end ornamental fish, which is called as “living water gem” and “Swimming art”. Because its doesn’t require high quality of the water, feeding with miscellaneous food, easy to breed, and thus they are welcomed by the people.
They usually are housed in a pool with artificial rockery or decorative ponds. Surprisingly, some of the varieties of can live over 200 years. The longest life expectancy is now known to a koi named Hanako. His age is 226 years old when he died.
Perhaps because of extreme cold Southern Ocean, this creature has a very slow growth rate. Some of the oldest individuals is estimated to have 1550 years old.
Although sponges are the simplest multicellular animals, but they are a huge family, amounting to more than 10,000 kinds of species, and accounting for 1/15 of all species of marine animals. Since the inner body has needle bone functioning a supporting role. And thus they are called spicules.
Usually based on the nature of spicules, it can be divided into calcareous sponges and non-calcareous sponges. The largest sponges is the one salvaged in 1909 in the Bahamas islands, with the girth of 183 cm, weight of 40 kg, and dried weight more 5 kg. In addition, there is sponges living in the Antilles of Netherlands, the height is 106 cm and the width 91.5 cm. The life of sponges is relatively long, and some species can live for hundreds of years.
2.Purple sea urchin
It is also known as red giant purple sea urchin. We can only find their traces in the Pacific Ocean. They are mainly living in the west coast of North American. They live in shallow areas, sometimes on the rocks, but they do not stay in place choppy. They used their body’s spines as stilts in the sea to crawl .
