Platypuses can give a low growl when disturbed, and a range of vocalisations have been reported in captivity. [16] Size varies considerably in different regions, with average weight from 0.7 to 2.4 kg (1 lb 9 oz to 5 lb 5 oz); males have average length 50 cm (20 in), while females are the smaller at 43 cm (17 in).

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.

[83] [84] 139 Upland cotton (Gossypium hirsutum) 52 This is for the cultivated species G. hirsutum (allotetraploid, 2n=4x=52). This species accounts for 90% of the world cotton ...
With a beaver’s tail, webbed feet, and a duck’s bill, platypuses are one of the world’s strangest-looking creatures. They are such an unusual mammal that the first scientists to study them ...
The platypus has an average body temperature of about 31 °C (88 °F) rather than the averages of 35 °C (95 °F) for marsupials and 37 °C (99 °F) for placentals. [ 30 ] [ 31 ] Research suggests this has been a gradual adaptation to the harsh, marginal environmental niches in which the few extant monotreme species have managed to survive ...

The world's largest platypus conservation centre has welcomed its first residents as part of a project to protect the semi-aquatic mammal found only in Australia amid threats to its habitat from ...
New Zealand Platypus species Platypus apicalis, Platypus caviceps and Platypus gracilis have an imperative impact in transmitting airborne and water-borne spore to contaminate the injuries, as there would be no effect from atmosphere on organisms developing in many parts of the nation. Spores can be either liberated from mycelium creating on ...
