What is the longest animal?
The longest animal in the world is probably Lineus longissimus , bootlace Worm, in Phylum Nemertertea, ribbon worms. One sample that was washed on the coast of St. Andrews in Scotland in 1864, measured 180 ft (55 m), almost twice as long as the longest blue whale that measured 98 ft (29.9 m). The worms are long and thin, with a thickness of only 5-10 mm (0.5 - 1 cm). When handling, they produce a large amount of thick mucus with a weak creeping odor. The animal is brown with lighter longitudinal stripes. If firmly folded, this longest animal on the record would occupy only about 17 cm (6.7 inches) on the side. Worms are often found between rocks, seaweed, barnacle or shells or buried in sand or gravel substrates, the worms of bootations are voracious predators. They wrap around prey, such as crustaceans or Annelids, which may be much larger than them, and repeatedly stab it with style in their proboscis until the target is dead. If there is no DISPOSilence no other food, it is said that the worms ribbons are consumed. They also eliminate the host from their proboscis on the trap of prey.
other animals except bootlace worm were fought for the title of the longest animal in the world. One of them is a siphonofor that looks and behaves as the only organism, but in fact it is a colony of very closely cooperating animals. Sihonofors are Cnidarians like jellyfish, and include Portuguese men about war. Some siphonophores were measured at 130 ft (39.6 m). Like the worms of the bootlace, they are long and thin, but their front end is led by two swimming bells. Unlike the worms of the bootlace, they are more free-grain than to the bottom. Siphonofors are rarely considered the world's longest animal in the world and the worm of Scotland from 1864 was longer, although most worms are much shorter.
other animals of the past that are now disappeared could fight for the title of NejdlThe neck of the animal, but because most of the soft animals never reduced, most are lost forever. One dinosaur, ampicoelialiad fragillimus , known only from fossils that have since disintegrated into dust, could be up to 196 ft (60 m) in length, even longer than the worm, but it is only a presumption, but no complete skeletal existence.
