Pixel 2 Specs(codenamed Walleye)
The Pixel 2, codenamed “Walleye,” is rumored to be manufactured by HTC. Specs expected for the device include a 4.97-inch FullHD display, a Qualcomm Snapdragon 835 chip, 4GB RAM, 64GB and 128GB internal storage options, a 12-megapixel rear camera with dual-LED flash and a 5-megapixel or 8-megapixel front camera and a 2,700mAh battery. The smartphone may also include a USB-C port and an IP68 water resistance rating.
Walleye, Sander vitreus
The common name, "walleye", comes from the fact that the fish's eyes point outward, as if looking at the walls. This externally facing orientation of the eyes gives anglers an advantage in the dark because there is a certain eyeshine given off by the eye of the walleye in the dark, similar to that of lions and other night dwelling animals. This "eyeshine" is the result of a light-gathering layer in the eyes called the tapetum lucidum, which allows the fish to see well in low-light conditions. In fact, many anglers look for walleyes at night since this is when major feeding patterns occur. The fish's eyes also allow them to see well in turbid waters (stained or rough, breaking waters), which gives them an advantage over their prey. Thus, walleye anglers will commonly look for locations where there is a good "walleye chop" (i.e., rough water). This excellent vision also allows the fish to populate the deeper regions in a lake, and they can often be found in deeper water, particularly during the warmest part of the summer and at night.

Function and mechanism
Choroid dissected from a calf's eye, tapetum lucidum appearing iridescent blue
Presence of a tapetum lucidum enables animals to see in dimmer light than would otherwise be possible.
The tapetum lucidum, which is iridescent, reflects light roughly on the interference principles of thin-film optics, as seen in other iridescent tissues. However, the tapetum lucidum cells are leucophores, not iridophores.
