As in the word ‘Tough’, that would mean to me the strongest animal. Today I’ve provided a list of the top 5 toughest living Creature on the planet. I’ve shared their characteristics and a brief explanation. The pure beauty of many of these animals is truly awe inspiring. I hope you will enjoy yourself as you will go through I think these are the toughest animals on the planet.Immortal Jellyfish
Turritopsis nutricula, the immortal jellyfish, is a hydrozoan whose medusa, or jellyfish, form can revert to the polyp stage after becoming sexually mature. It is the only known case of a metazoan capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary stage. It does this through the cell development process of transdifferentiation. Cell transdifferentiation is when the jellyfish “alters the differentiated state of the cell and transforms it into a new cell”.
In this process the medusa of the immortal jellyfish is transformed into the polyps of a new polyp colony. First, the umbrella reverts itself and then the tentacles and mesoglea get resorbed. The reverted medusa then attaches itself to the substrate by the end that had been at the opposite end of the umbrella and starts giving rise to new polyps to form the new colony.
Theoretically, this process can go on indefinitely, effectively rendering the jellyfish biologically immortal,although in nature, most Turritopsis, like other medusae, are likely to succumb to predation or disease in the plankton stage, without reverting to the polyp form.
No single specimen has been observed for any extended period, so it is not currently possible to estimate the age of an individual, and so even if this species has the potential for immortality, there is no laboratory evidence of many generations surviving from any individual.
Shocking Pink Dragon Millipede
The Shocking Pink Dragon Millipede (Desmoxytes purpurosea) is a spiny and toxic millipede named for its vivid pink color. First discovered in 2007 in the Hup Pa Tard limestone cavern in Thailand, within the Greater Mekong, the adult millipede is approximately 3 cm long and lives in the open on leaf litter.
The millipedes have glands that produce hydrogen cyanide to protect them from predators, a fact advertised by their aposematic color.Because they produce cyanide, they smell like almonds.The shocking pink dragon millipede was named third in the top ten species in 2008 by the International Institute for Species Exploration.
The frilled shark (Chlamydoselachus anguineus) is one of two extant species of shark in the family Chlamydoselachidae, with a wide but patchy distribution in the Atlantic and Pacific Oceans. This uncommon species is found over the outer continental shelf and upper continental slope, generally near the bottom though there is evidence of substantial upward movements.
It has been caught as deep as 1,570 m (5,150 ft), whereas in Suruga Bay, Japan it is most common at depths of 50–200 m (160–660 ft). Exhibiting several “primitive” features, the frilled shark has often been termed a “living fossil”. It reaches a length of 2 m (6.6 ft) and has a dark brown, eel-like body with the dorsal, pelvic, and anal fins placed far back. Its common name comes from the frilly or fringed appearance of the gill slits, of which there are six pairs with the first pair meeting across the throat.
Seldom observed, the frilled shark is speculated to capture its prey by bending its body and lunging forward like a snake. The long, extremely flexible jaws enable it to swallow large prey whole, while the many rows of small, needle-like teeth prevent escape. It feeds mainly on cephalopods, while also consuming bony fishes and other sharks.
This species is aplacental viviparous: the embryos emerge from their egg capsules inside the mother’s uterus, and are sustained to term primarily by yolk. The gestation period may be as long as three and a half years, the longest of any vertebrate. Between 2 and 15 young are born at a time; there is no distinct breeding season.
Frilled sharks are occasionally captured as bycatch by commercial fisheries but have little economic value. The International Union for Conservation of Nature (IUCN) has assessed it as Near Threatened, since given its very low reproductive rate even incidental catches may deplete its population. This shark, or a supposed giant relative, has been suggested as a source for reports of sea serpents.
Giant African Land Snail
The East African land snail, or giant African land snail, scientific name Achatina fulica, is a species of large, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinidae.
The adult snails have a height of around 7 centimetres (2.8 in), and their length can reach 20 centimetres (7.9 in) or more.
The shell has a conical shape, being about twice as high as it is broad. Either clockwise (sinistral) or counter-clockwise (dextral) directions can be observed in the coiling of the shell, although the right-handed (dextral) cone is the more common. Shell colouration is highly variable, and dependent on diet. Typically, brown is the predominant colour and the shell is banded.
As they develop rapidly and produce large numbers of offspring, this mollusc is now listed as one of the top 100 invasive species in the world.It is a voracious feeder, and recognized as a serious pest organism affecting agriculture, natural ecosystems, and human health and commerce. As such, it has been given top national quarantine significance in the United States. Quarantine officials have successfully intercepted or eradicated incipient invasions on the mainland in the past.
The Komodo dragon (Varanus komodoensis), also known as the Komodo monitor, is a large species of lizard found in the Indonesian islands of Komodo, Rinca, Flores, Gili Motang and Padar. A member of the monitor lizard family (Varanidae), it is the largest living species of lizard, growing to a maximum length of 3 metres (10 ft) in rare cases and weighing up to around 70 kilograms (150 lb).Their unusual size has been attributed to island gigantism, since there are no other carnivorous animals to fill the niche on the islands where they live.
However, recent research suggests that the large size of Komodo dragons may be better understood as representative of a relict population of very large varanid lizards that once lived across Indonesia and Australia, most of which, along with other megafauna,died out after the Pleistocene.
Fossils very similar to V. komodoensis have been found in Australia dating to greater than 3.8 million years ago, and its body size remained stable on Flores, one of the handful of Indonesian islands where it is currently found, over the last 900,000 years, “a time marked by major faunal turnovers, extinction of the island’s megafauna, and the arrival of early hominids by 880 ka.”
As a result of their size, these lizards dominate the ecosystems in which they live. Komodo dragons hunt and ambush prey including invertebrates, birds, and mammals. Their group behaviour in hunting is exceptional in the reptile world. The diet of big Komodo dragons mainly consists of deer, though they also eat considerable amounts of carrion.
Mating begins between May and August, and the eggs are laid in September. About twenty eggs are deposited in abandoned megapode nests or in a self-dug nesting hole. The eggs are incubated for seven to eight months, hatching in April, when insects are most plentiful. Young Komodo dragons are vulnerable and therefore dwell in trees, safe from predators and cannibalistic adults. They take about eight to nine years to mature, and are estimated to live for up to 30 years.
Komodo dragons were first recorded by Western scientists in 1910.Their large size and fearsome reputation make them popular zoo exhibits. In the wild their range has contracted due to human activities and they are listed as vulnerable by the IUCN.They are protected under Indonesian law, and a national park, Komodo National Park, was founded to aid protection efforts.
