Newts do not have a coronary artery on the ventricle, due to circulation that is found in the conus arteriosus. Newts contain a special circulatory adaptation that allows them to survive ventricular penetration : when a newt's ventricle is punctured, the heart will divert the blood directly into an ascending aorta via a duct located between the ...
Several passages have reference to this bird, its periodical migrations (Jeremiah 8:7), its nesting in fir-trees, its black pinions stretching from its white body (Zechariah 5:9; D.V., kite; but the stork, hasîdhah, is mentioned in the Hebrew text). Two kinds, the white and the black stork, live in Israel during the winter.
The red eft (juvenile) stage is a bright orangish-red, with darker red spots outlined in black. An eastern newt can have as many as 21 of these spots. The pattern of these spots differs among the subspecies. An eastern newt's time to get from larva to eft is about three months.
The venter of the black-spotted newt is yellow to orange. [6] They have smooth skin, and a paddle-shaped, vertically flattened tail. The black-spotted newt (Notophthalmus meridionalis) has a lighter dorsum color than the Mexican newt (Notophthalmus kallerti). [6] The larvae of the black-spotted newt are generally gray-brown and have a dark ...
Calotriton and Triturus are estimated to have split approximately 8 myr ago. This may have been associated with adaptation to fast-running, well-oxygenated mountain streams (instead of ponds in Triturus), leading to some superficial similarity with Euproctus in convergent evolution: strongly depressed head and body, and reduction or even absence of lungs.
Breeding males have a large wavy crest that runs from its neck down to the tip of its tail, but is a little bit shorter where the tail meets the body. The crest is striped yellowish-white with black. Adult marbled newts range from 5 inches (13 cm) to 6.5 inches (17 cm) long. [4]
The newts have rough skin, and are dark brown on the back and sides, with black spots and heavy white stippling on the flanks. The female has a yellow line running along the lower tail edge. The throat is mixed yellow–black with fine white stippling, the belly yellow to orange with dark, irregular blotches. [7]: 342
