The sizes of bobcats' home ranges vary significantly from 0.596–326 km 2 (0.23–126 sq mi). [38] One study in Kansas found resident males to have ranges of roughly 21 km 2 (8 sq mi), and females less than half that area. Transient bobcats were found to have home ranges of 57 km 2 (22 sq mi) and less
A simple eye or ocellus (sometimes called a pigment pit [1] [2]) is a form of eye or an optical arrangement which has a single lens without the sort of elaborate retina that occurs in most vertebrates. These eyes are called "simple" to distinguish them from "compound eyes", which have multiple lenses. They are not necessarily simple in the ...
In humans, the pupil is circular, but its shape varies between species; some cats, reptiles, and foxes have vertical slit pupils, goats and sheep have horizontally oriented pupils, and some catfish have annular types. [3] In optical terms, the anatomical pupil is the eye's aperture and the iris is the aperture stop.
Bobcats: No. Bobcats are a native species with a legal hunting season in Florida that runs from Dec. 1 through March 31. Bobcats may be taken by rifle, shotgun, pistol, muzzleloader, air gun ...
In the early years of the 20th century, bobcats (Lynx rufus) were reported as "somewhat common" in the park. There have been 9 to 14 reported sightings each decade since 1960. These sightings have occurred throughout the park; about 80 percent have occurred in the northern half. Bobcats have been reported in about equal numbers during all seasons.
The tapetum lucidum, in animals that have it, can produce eyeshine, for example as seen in cat eyes at night. Red-eye effect, a reflection of red blood vessels, appears in the eyes of humans and other animals that have no tapetum lucidum, hence no eyeshine, and rarely in animals that have a tapetum lucidum. The red-eye effect is a photographic ...
Owls have very large eyes for their size, 2.2 times greater than the average for birds of the same weight, [14] and positioned at the front of the head. The eyes have a field overlap of 50–70%, giving better binocular vision than for diurnal birds of prey (overlap 30–50%). [77]
Most arthropods have at least one of two types of eye: lateral compound eyes, and smaller median ocelli, which are simple eyes. [2] When both are present, the two eye types are used in concert because each has its own advantage. [3] Some insect larvae, e.g., caterpillars, have a different type of simple eye known as stemmata.
