Milne4, Nicholas S. Gladstone5, Annette S. Engel6, John B. Jensen7, Carlos D. Camp8, James C. Ozier9, and Alan Cressler10 Abstract We provide an annotated checklist of species recorded from caves and other subterranean habitats in the state of Georgia, USA. We report 281 species (228 invertebrates and 53 vertebrates), including 51 troglobionts (cave-obligate species), from more than 150 sites (caves, springs, and wells). Endemism is high; of the troglobionts, 17 (33 % of those known from the state) are endemic to Georgia and seven (14 %) are known from a single cave. We identified three biogeographic clusters of troglobionts. Two clusters are located in the northwestern part of the state, west of Lookout Mountain in Lookout Valley and east of Lookout Mountain in the Valley and Ridge. In addition, there is a group of tro- globionts found only in the southwestern corner of the state and associated with the Upper Floridan Aquifer. At least two dozen potentially undescribed species have been collected from caves; clarifying the taxonomic status of these organisms would improve our understanding of cave biodiversity in the state.

GET TO KNOW MISSOURI’S SNAKES Snakes have generated more fear and misunderstanding than any other group of animals. Psychologists have proven that a fear of snakes (called ophidiophobia) is acquired; we are not born with it. Once people learn some of the interesting facts about snakes and discover that most of them are harmless and beneficial, their aversion may diminish. With patience and understanding, almost anyone can overcome a dread of snakes and actually enjoy studying them. One thing is certain — even people with a well-developed fear of snakes are curious about them.

    Eastern Wormsnake Carphophis Amoenus

    Natural Heritage Eastern Wormsnake & Endangered Species Carphophis amoenus Program State Status: Threatened www.mass.gov/nhesp Federal Status: None Massachusetts Division of Fisheries & Wildlife DESCRIPTION: Eastern Wormsnakes are small, glossy, thin snakes, and range from 18-37 cm (7-14.5 inches) in length. The body is unpatterned, gray or tan to dark brown. Distinguishing characteristics include a slightly flattened and pointed nose, small eyes, and a pink venter. Venter coloration extends onto sides of body to include 1st to 2nd scale rows. The tail length is short and has a blunt spine-like tip. The body typically has 13 scale rows. The scales are unkeeled and the annual plate is divided. They are a non-venomous snake in the Coluidae family. Based on research conducted in Kentucky, females Eastern Wormsnakes are slightly larger than males (mass: F = about 6.6g, M = about 4.6g); number of ventral scales (F = 112-150, M = 106-138). However, Copyright J.D.Wilson, 2006; www.discoverlife.org males have a longer tail length/body length (F = 11.3- 20.3, M = 13.4-20.4) and greater average number of SIMILAR SPECIES IN MASSACHUSETTS: There subcaudal scales (F = 14-36, M = 25-40). are three small snakes in Massachusetts that may be confused with the Eastern Wormsnake. The little brown Juveniles look like adults but the pattern is darker brown snake (Storeria dekayi) has a faint pattern of parallel and the venter brighter pink. spotting on the dorsum and lacks a pointed snout. The ring-necked snake (Diadophis punctatus) has a distinct cream or yellow colored ring across the neck and a cream colored venter; some have black crescent-shaped spots down the mid-venter.
