The body mass varies between 1.3 g (0.046 oz) [9] and 2.5 g (0.088 oz) [4] [8] and is usually about 1.8 g (0.063 oz). [3] In comparison, the related greater white-toothed shrew can be twice as long and weighs four to five times more. [8] The head is relatively large, with a long, mobile proboscis, and the hind limbs are relatively small. [10]
The largest species of dragonfly is Tetracanthagyna plagiata of Southeast Asia, spanning up to 17.6 cm (6.9 in) and measuring up to 11.8 cm (4.6 in) long; while bulkier and heavier than Megaloprepus (at up to 7 g (0.25 oz)), it is smaller in its linear dimensions.

The dugong (/ ˈ d (j) uː ɡ ɒ ŋ /; Dugong dugon) is a marine mammal.It is one of four living species of the order Sirenia, which also includes three species of manatees.It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century.
It was notable as a dicephalic animal for surviving into adulthood with two perfect heads. Scientists have published in modern journals about dissecting such animals since at least the 1930s. [10] A 1929 paper studied the anatomy of a two-headed kitten. [10] Polycephalic animals, due to their rarity, are a subject of novelty.
At 8 kilometres (5 mi) across, and estimated at 100,000 years old, [3] it may be one of the largest and oldest clonal colonies on Earth. [4] [5] [6] Among animals, the largest species are all marine mammals, specifically whales. The blue whale is believed to be the largest animal to have ever lived. [7]
Four classes of arthropods each provide multiple examples, including sea spiders (with 4 to 6 leg pairs, [11] providing two examples) and pauropods (adults with 8 to 11 leg pairs, [12] providing four examples), but most of the examples listed are either millipedes (adults with 11 to 653 leg pairs) [5] [1] or centipedes (adults with 15 to 191 ...
The longest recently documented Chinese giant salamander, kept at a farm in Zhangjiajie, was 1.8 m (5.9 ft) in 2007. [6] At 59 kg (130 lb), both this individual, and a 1.4 m (4.6 ft) long, 52 kg (114 lb) individual found in a remote cave in Chongqing in December 2015, surpassed the species' typically reported maximum weight.
The average lifespan of an echidna in the wild is estimated at 14–16 years. Fully grown females can weigh about 4.5 kilograms (9.9 lb), the males 33% larger, at about 6 kilograms (13 lb). [12] Though the internal reproductive organs differ, both sexes possess an identical single cloaca opening for urination, defecation, and mating. [6]
