Mosquito has 47 teeth in its mouth . Mosquito and mosqita (from the Spanish meaning little fly is a common insect in the family Culicidae (from the Latin culex meaning midge or gnat). Mosquitoes resemble crane flies (family Tipulidae) and chironomid flies (family Chironomidae), with which they are sometimes confused by the casual observer. There are about 3,500 species of mosquitoes found throughout the world. In some species of mosquito, the females feed on humans, and are therefore vectors for a number of infectious diseases affecting millions of people per year. ======================================= visit my website - > Dr.Seshagirirao.com

whale is about 100 feet length , weight 200 tons , heart is about a car tengh , widht of mouth is 30 feet , takes 4,ooo kgs of food per day. life span is about 40 years. Whale is the common name for marine mammals of the order Cetacea. The term whale is sometimes used to refer to all cetaceans, but in more common English usage it generally excludes the members of the Delphinoidea superfamily, such as dolphins and porpoises. These smaller species belong to the suborder Odontoceti (toothed whales), which also includes the sperm whale, killer whale, pilot whale, and beluga whale. The other suborder of cetaceans, Mysticeti (baleen whales), includes the blue whale, which is the largest animal known to have ever existed, the humpback whale, and many other animals that feed by straining seawater through long strips of baleen that they have in the place of teeth, and from which they get their name.

- Americans are eating nearly 50 kilos of chokolates per one second . in indicates that they are more fond of sweets like chocolates ... America population is about 28 crores and as such how much they are eating /sec. chokolates are high calorific diet and contains more of fats ... hence may leads to different heart diseases .

Sleep is very important to every living creature . Elephant sleeps about Two hours per day .
About Sleep :
The amount and nature of sleep is correlated with age, body size and ecological variables, including life in the terrestrial vs. aquatic environment, diet and the safety of the sleeping site. The sleep phylogeny literature suggests that sleep reduces activity to the amount needed for feeding and species reproduction, and maximizes energy conservation, thereby furthering genetic survival. Theories of REM sleep function have suggested that in addition to these functions, this state may have a role in periodic brain activation during sleep, in localized brain and body recuperative processes and in emotional regulation.
Daily sleep amounts vary substantially throughout the mammalian class. Some animals, such as bats and opossums, sleep for 18-20 h/day (Fig. 1), whereas others, such as the elephant and giraffe, sleep as little as 3-4 h/day. One might expect that species in each mammalian order would have a similar pattern of sleep because of their defining genetic, behavioral, and anatomical similarities. However, this is not the case. Primates as a group or carnivores as a group or rodents as a group do not have a characteristic sleep duration. Sleep time in these various orders overlaps extensively and any “order related” contribution to sleep duration must be small relative to other factors (Zepelin et al., 2005). Human sleep does not appear to be quantitatively unique in its duration or in the proportion or absolute amount of REM sleep.
Daily sleep amounts are highest in carnivores, lower in omnivores and lowest in herbivores. Sleep time is inversely correlated with body mass in herbivores. This correlation is responsible for a significant overall correlation between body mass and sleep time over all mammals studied to date (Zepelin et al., 2005)
