Synophis lasallei, also known as La Salle's shadow snake, is a species of snake in the family, Colubridae. It is found in Colombia and Ecuador.
Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes. Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads. To accommodate their narrow bodies, snakes' paired organs appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have independently evolved elongate bodies without limbs or with greatly reduced limbs at least twenty-five times via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal.
The king cobra is a venomous snake endemic to Asia. The sole member of the genus Ophiophagus, it is not taxonomically a true cobra, despite its common name and some resemblance. With an average length of 3.18 to 4 m and a maximum record of 5.85 m (19.2 ft), it is the world's longest venomous snake. The species has diversified colouration across habitats, from black with white stripes to unbroken brownish grey. The king cobra is widely distributed albeit not commonly seen, with a range spanning from Indian Subcontinent through Southeastern Asia to Southern China, where it preys chiefly on other snakes, including those of its kind. This is the only ophidian that constructs an aboveground nest for its eggs which are purposefully and meticulously gathered and protected by the female throughout the incubation period.
Colubridae is a family of snakes. With 249 genera, it is the largest snake family. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on every continent except Antarctica.
Squamata is the largest order of reptiles, comprising lizards, snakes, and amphisbaenians, which are collectively known as squamates or scaled reptiles. With over 11,500 species, it is also the second-largest order of extant (living) vertebrates, after the perciform fish. Members of the order are distinguished by their skins, which bear horny scales or shields, and must periodically engage in molting. They also possess movable quadrate bones, making possible movement of the upper jaw relative to the neurocranium. This is particularly visible in snakes, which are able to open their mouths very wide to accommodate comparatively large prey. Squamates are the most variably sized living reptiles, ranging from the 16 mm (0.63 in) dwarf gecko to the 6.5 m (21 ft) Reticulated python. The now-extinct mosasaurs reached lengths over 14 m (46 ft).
Ophidia is a group of squamate reptiles including modern snakes and reptiles more closely related to snakes than to other living groups of lizards.
The Colubrinae are a subfamily of the family Colubridae of snakes. It includes numerous genera, and although taxonomic sources often disagree on the exact number, The Reptile Database lists 717 species in 92 genera as of September 2019. It is the second largest subfamily of colubrids, after Dipsadinae. Many of the most commonly known snakes are members of this subfamily, including rat snakes, king snakes, milk snakes, vine snakes, and indigo snakes.
Atractus is a genus of colubrid ground snakes in the subfamily Dipsadinae. The genus includes more than 140 distinct species.
Synophis is a genus of snakes in the family Colubridae. The genus is endemic to northwestern South America.
Synophis bicolor, known commonly as the bicolored shadow snake or the two-colored fishing snake, is a species of snake in the family Colubridae. The species is endemic to northwestern South America.
Synophis calamitus, the calamitous shadow snake, is a species of snake in the family Colubridae. The species is endemic to northwestern South America.
Synophis bogerti, known commonly as Bogert's fishing snake or Bogert's shadow snake, is a species of snake in the family Colubridae. The species is endemic to northwestern South America.
Synophis insulomontanus, known commonly as the mountain shadow snake, is a species of snake in the family Colubridae. The species is endemic to northwestern South America.
Emmochliophis is a genus of snakes in the family Colubridae. The genus is endemic to Ecuador.
The Colubroides are a clade in the suborder Serpentes (snakes). It contains over 85% of all the extant species of snakes. The largest family is Colubridae, but it also includes at least six other families, at least four of which were once classified as "Colubridae" before molecular phylogenetics helped in understanding their relationships. It has been found to be monophyletic.
Afrophidia is a clade of alethinophidian snakes comprising the groups Henophidia and Caenophidia, essentially making up the snakes people commonly associate with. The name refers to the deep split between Afrophidia and their sister taxon, Amerophidia, which originated in South American origin, and the afrophidians was recently hypothesized to represent a vicariant event of the breakup of Gondwanan South America and Africa.
Atractus lasallei, Lasalle's ground snake, is a species of snake in the family Colubridae. The species can be found in Colombia.

Synophis plectovertebralis, also known as the braided shadow snake, is a species of snake in the family, Colubridae. It is found in Colombia.
Synophis zaheri, also known as Zaher's shadow snake, is a species of snake in the family, Colubridae. It is found in Ecuador.
