Holbrookia
''Holbrookia'' is a genus of earless lizards, known commonly as the lesser earless lizards, in the Family (biology), family Phrynosomatidae. The genus contains six recognized species, which are found throughout the Southwestern United States, Southwestern and Central United States and northern Mexico. They are characterized by having no external ear openings, presumably to prevent soil from entering their bodies when they are digging. Etymology The Genus, generic name, ''Holbrookia'', is in honor of Americans, American Zoology, zoologist John Edwards Holbrook. Description Lesser earless lizards grow to about 2.0–2.5 in (50–65 mm) Snout–vent length, snout-to-vent length (SVL), plus a tail of 3–4 in (75–100 mm). They are typically grey or tan in color, with black blotching. The males usually have blue patches on either side of their bellies, whereas the females do not. Females often change to have bright orange patches when gravid. Behavior ''Holbrookia'' sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Holbrookia Maculata Approximans
''Holbrookia approximans'', the speckled earless lizard, is a species of earless lizard which is found in the Southwestern United States and northern Mexico.

Phrynosomatidae
The Phrynosomatidae are a diverse family of lizards, sometimes classified as a subfamily (Phrynosomatinae), found from Panama to the extreme south of Canada. Many members of the group are adapted to life in hot, sandy deserts, although the spiny lizards prefer rocky deserts or even relatively moist forest edges, and the short-horned lizard lives in prairie or sagebrush environments. The group includes both oviparous (egg-laying) and viviparous species, with the latter being more common in species living at high elevations. Oviparous and viviparous species of Phrynosomatidae lizards co-localize in certain areas of the United States, including New Mexico. The earliest fossil remains of this group are known from the Late Cretaceous of Mongolia Mongolia is a landlocked country in East Asia, bordered by Russia to the north and China to the south and southeast. It covers an area of , with a population of 3.5 million, making it the world's List of countries and dependenci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earless Lizard
Earless lizards are two genera of small lizards native to the semiarid and grassland habitats of the Southwestern United States and Mexico. The genus '' Cophosaurus'' and the genus '' Holbrookia'' are both characterized by having no external ear openings, presumably to prevent sand from entering their bodies as they dig. Distinctive features Earless lizards typically vary from long. Males tend to be larger than females. The male has two heavy black strips ahead of its hind legs (pictured). The female differs in that she has a black stripe behind each thigh. A pink throat and flanks indicate pregnancy. Earless lizards have two throat folds, large eyes, and 27 or fewer femoral pores. They are also described as having shorter fore legs compared to their hind legs and also rather long toes. Although they are called earless lizards, they are still completely capable of hearing, but their ears do not have an external opening. This feature is useful when they burrow underground without ...

John Edwards Holbrook
John Edwards Holbrook (December 31, 1796 – September 8, 1871) was an American zoologist, herpetologist, physician, and naturalist, born in Beaufort, South Carolina, the son of Silas Holbrook, a teacher, and Mary Edwards. Although Holbrook's memoir, written by his medical partner, and his tombstone both give the date 1794 for his birth, this is incorrect. Holbrook received his A.B. degree from Brown University in 1815, and his M.D. from the University of Pennsylvania in 1818. In 1827, he married Harriott Pinckney Rutledge, granddaughter of John Rutledge and a member of the Middleton-Rutledge-Pinckney family. He provided the first comprehensive illustrated account of North American amphibians and reptiles in the two editions of his ''North American Herpetology; or, A Description of the Reptiles Inhabiting the United States''. The first edition in four volumes (1836–1840) is very rare because Holbrook attempted to destroy all copies in a bonfire in his backyard over unfavorable c ...

Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontology, paleontologist, comparative anatomy, comparative anatomist, herpetology, herpetologist, and ichthyology, ichthyologist. Born to a wealthy Quaker family, he distinguished himself as a child prodigy interested in science, publishing his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the Western United States, American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey, U.S. Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition now known as the Bone Wars. Cope's financial fortunes soured after failed mining ventures i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marie Firmin Bocourt
Marie Firmin Bocourt (19 April 1819 – 4 February 1904) was a French zoologist and artist. As a young man, he worked as a preparateur for the zoologist Gabriel Bibron (1805–1848), later serving as a museum artist. In 1861, he was sent to Thailand (then called Siam), where he explored the fauna and brought back an important collection of specimens. xiii + 244 pp. (Bocourt, p. 25). He collaborated with Auguste Duméril (1812–1870) on a series called ''Mission scientifique au Mexique et dans l'Amérique Centrale'', a result of Bocourt's scientific expedition to Mexico and Central America in 1864–1866, in one part during the Second French intervention in Mexico, French Intervention in Mexico led by Louis-Napoleon Bonaparte, Napoleon III. Auguste Duméril died in 1870, and the project was continued by Bocourt with assistance from Léon Vaillant (1834–1914), François Mocquard (1834–1917) and Fernand Angel (1881–1950). With Vaillant, he published a study on fishes, "''Étud ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diurnal Animal
Diurnality is a form of plant and animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which preferred pollinator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
