In cryptozoology and ufology, "rods" (also known as "skyfish", "air rods", or "solar entities") are elongated visual artifacts appearing in photographic images and video recordings. Most optical analyses to date have concluded that the images are insects moving across the frame as the photo is being captured, although cryptozoologists and ...
Within the retina, rod cells provide high visual sensitivity (at the cost of acuity), being used in low light conditions. Cone cells provide higher spatial and temporal resolution than rods can, and allow for the possibility of colour vision by comparing absorbances across different types of cones which are more sensitive to different wavelengths.
Nocturnal mammals have rods with unique properties that make enhanced night vision possible. The nuclear pattern of their rods changes shortly after birth to become inverted. In contrast to conventional rods, inverted rods have heterochromatin in the center of their nuclei and euchromatin and other transcription factors along the border.
Ancistrus is a genus of nocturnal freshwater fish in the family Loricariidae of order Siluriformes, native to freshwater habitats in South America and Panama.Fish of this genus are common in the aquarium trade where they are known as bushynose or bristlenose catfish.
They are nocturnal piscivorous drift-hunters. [32] The body is covered in ctenoid elasmoid scales that act as armor. [33] Coelacanths have eight fins – two dorsal fins, two pectoral fins, two pelvic fins, one anal fin and one caudal fin. The tail is very nearly equally proportioned and is split by a terminal tuft of fin rays that make up its ...

The shift to a nocturnal lifestyle would demand more rod photoreceptors to absorb the blue light emitted by the moon during the night. [32] It can be extrapolated that the high ratio of rods to cones present in modern human eyes was retained even after the shift from nocturnal back to diurnal.
The Los Angeles Chargers had one of the odder drives in NFL playoff history on Saturday. Down 23-6 against the Houston Texans in the fourth quarter with their odds of a win slipping away, Chargers ...
