The bad news was that the bugs didnât die nearly as quickly as other studies had found, a mere hour or two at -16Â° or -17Â° Celsius. âIn our study, bedbugs survived lower temperatures, with eggs surviving in short-term exposures â¦ to temperatures as low as -25Â° C,â the researchers write. But the bugs are not freeze tolerant, the scientists found, and they can be killed â no matter their stage of life or feeding status.
1 The average weight of the hippopotamus male measures around 1.500 â 1.800 kg (3,300 â 4,000 lb). 2  Males are slightly heavier as compared to females. 3  However, females weigh around 1,300 â 1,500 kg (2,900 â 3,300 lb).
Both the mandrill and the drill were once classified as baboons in the genus Papio, but recent research has determined that they should be separated into their own genus, Mandrillus. Mandrills are the world's largest monkeys.he mandrill has one of the greatest sexual dimorphisms among the primates. Males typically weigh 19â37 kg (42â82 lb), with an average mass of 32.3 kg (71 lb). Females weigh roughly half as much as the male, at 10â15 kg (22â33 lb) and an average of 12.4 kg (27 lb).
