Therefore, small fishes were tried as alternative food to Simophis rhinostoma, since we have observed its acceptance by non-piscivorous colubrid
species kept in captivity.
Prey items of 20 species of the neotropical colubrid
snake genus Liophis.
Our observations reveal that in Scaphiodontophis the females start coital separation whereas in other colubrids
it is the male who starts this process (Shaw 1951).
Abstract.--Six species of colubrid
snakes from California were examined for helminths: Arizona elegans, Chionactis occipitalis, Masticophis flagellum, Masticophis lateralis, Phyllorhynchus decurtatus and Rhinocheilus lecontei.
Relative mass of clutch in Pituophis is typical of that for other oviparous colubrids
(0.34 for 43 samples in Seigel and Fitch, 1984; 0.32 for 18 samples in Dunham et al., 1988).
Radiation within the advanced snakes (Caenophidia) with special emphasis on African opistoglyph colubrids
, based on mitochondrial sequence data.
angulatus venom, since crude venom and peak 1 were only positive on gelatin up 1/4 dilutions compared with other "colubrids
" and Bothrops venoms (Furtado et al.
tetrapoda as a generalist parasite of the colubrids
Testicular histology was similar to that reported by Goldberg & Parker (1975) for two colubrids
Masticophis taeniatus and Pituophis catenifer (= P.
However, both brown and banded patterns are found on rear-fanged colubrids
at La Selva, and one of the banded patterns (reverse tricolor) is only found on a nonvenomous snake.
What is known about activity patterns of snakes is based primarily upon studies of diurnal, medium-to-large bodied colubrids
(Gregory, 1984; Gregory and Nelson, 2002; Krysko, 2002; Bell et al., 2007) or viperids (Gannon and Secoy, 1985; Beverlander et al., 2006; Marshall et al., 2006), and recently on tropical and sub-tropical species of snakes (Marques et al., 2001; Brown and Shine, 2002).
Snakes such as Tantilla melanocephala (Linnaeus, 1758), Ninia atrata (Hallowell, 1845), Leptodeira annulata (Linnaeus, 1758), Atractus torquatus (Dumeril, Bibron et Dumeril, 1854), and other unidentified colubrids
, have been found in B.
