The dorsal fins of the white crappie start farther back on the body than those of the black crappie. The anal fin is about the same size as the dorsal fin. [7] The white crappie has six dorsal fin spines, whereas the black crappie has seven or eight dorsal fin spines. [7] White crappies are also slightly more elongated than black crappies. [8]
Hybrid crappie (Pomoxis annularis × nigromaculatus) have been cultured and occur naturally. [22] The crossing of a black crappie female and white crappie male has better survival and growth rates among offspring than the reciprocal cross does. [22] Hybrid crappie are difficult to distinguish from black crappie by appearance alone.
The black crappie (Pomoxis nigromaculatus) is a freshwater fish in the sunfish family (Centrarchidae). It is endemic to North America , one of the two types of crappies . It is very similar to the white crappie ( P. annularis ) in size, shape, and habits, except that it is darker, with a pattern of black spots.
So, the commission opted to reduce the limit on the lakes from 15 crappie to 10 crappie over 12 inches in length per angler per day and no more than 25 crappie per boat per day.
Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night. Matutinal, a classification of organisms that are only or primarily active in the pre-dawn hours or early morning.
The kiwi is a family of nocturnal birds endemic to New Zealand.. While it is difficult to say which came first, nocturnality or diurnality, a hypothesis in evolutionary biology, the nocturnal bottleneck theory, postulates that in the Mesozoic, many ancestors of modern-day mammals evolved nocturnal characteristics in order to avoid contact with the numerous diurnal predators.

Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...
