The northern leopard frog breeds in the spring (March–June). Up to 6500 eggs are laid in water, and tadpoles complete development within the breeding pond. Tadpoles are light brown with black spots, and development takes 70–110 days, depending on conditions. Metamorph frogs are 2–3 cm (0.79–1.18 in) long and resemble the adult.
Tadpole 2015-04-16-12.04.26 ZS PMax (16571152244) (2) After they hatch, they remain tadpoles for two to three months before transforming into frogs and are ready to leave the water. [32] Following breeding in the spring, the spring peepers' larval stage lasts two to three months. [30] The spring peeper can live an estimated three years in the ...
Tadpole of A. americanus. The American toad lays between 2,000-20,000 eggs in two strings which hatch in 3-12 days. [7] The hatched tadpoles, while very small, are recognizable by their skinny tails in relation to the size of their round black bodies. They reach adulthood in 50–65 days.
The nutmegs are roughly egg-shaped, about 20.5–30 mm (0.81–1.18 in) long and 15–18 mm (0.59–0.71 in) wide, weighing 5–10 g (0.18–0.35 oz) dried. [ 6 ] Two other species of genus Myristica with different flavors, M. malabarica and M. argentea , are sometimes used to adulterate nutmeg as a spice.
Fog particles are around 10–50 μm (0.00039–0.00197 in) long. To help compare different orders of magnitude, this section lists lengths between 10 −5 m and 10 −4 m (10 μm and 100 μm). 10 μm – width of cotton fibre [94] 10 μm – tolerance of a Lego brick [95]
Dams can range in height from 20 cm (7.9 in) to 3 m (9.8 ft) and can stretch from 0.3 m (1 ft 0 in) to several hundred meters long. Beaver dams are more effective in trapping and slowly leaking water than man-made concrete dams. Lake-dwelling beavers do not need to build dams. [59] Open-water beaver lodge in Canada

The penis bone of males is about 10 cm (3.9 in) long and strongly bent at the front end, [101] [102] and its shape can be used to distinguish juvenile males from mature males. [ 103 ] [ 104 ] [ 105 ] Seven of the thirteen identified vocal calls are used in communication between the mother and her kits, one of these being the birdlike twittering ...
