caecilians

The caecilians (pronounced /siːˈsɪliən/) are an order (Gymnophiona) of amphibians that superficially resemble earthworms or snakes. They mostly live hidden in the ground, which makes them one of the least known orders of amphibians.




Caecilians completely lack limbs, making the smaller species resemble worms, while the larger species with lengths up to 1.5 m (4 ft 11 in) resemble snakes. The tail is short or absent, and the cloaca is near the end of the body.


The skin also has numerous ring-shaped folds, or annuli, that partially encircle the body, giving them a segmented appearance. Like other living amphibians, the skin contains glands that secrete a toxin to deter predators.[1] The skin secretions of Siphonops paulensis have been shown to have hemolytic properties.

Caecilians are the only order of amphibians that use internal insemination exclusively (although the tailed frog in the U.S. does use a tail-like appendage for internal insemination in its fast flowing water environment). The male caecilians have a penis-like organ, the phallodeum, which is inserted into the cloaca of the female for 2 to 3 hours. About 25% of the species are oviparous (egg-laying); the eggs are guarded by the female. For some species the young caecilians are already metamorphosed when they hatch; others hatch as larvae. The larvae are not fully aquatic, but spend the daytime in the soil near the water.

The diet of caecilians is not well-known. Mature caecilians seem to feed mostly on insects and other invertebrates found in the habitat of the respective species. The stomach contents of 14 specimens of Afrocaecilia taitana consisted of mostly undefinable organic material and plant remains. Where identifiable remains were most abundant, they were found to be termite heads.[7] While it was suggested[specify] that the undefinable organic material shows that the caecilians eat detritus, others believe these are in fact the remains of earthworms.

Eastern Milk Snake

The Milk Snake (Lampropeltis triangulum; French: Couleuvre tachetée; Spanish: Culebra-real coralillo, Lithuanian: Pieninė gyvatė)[1] is a species of king snake. There are 25 subspecies among the milk snakes, including the commonly named scarlet kingsnake (L. t. elapsoides).[



The subspecies have strikingly different appearance, and many of them have their own common names. Some authorities suggest that this species may be split into several separate species.[1] They are distributed from southeastern Canada, through most of the continental United States, to Central America, down to western Ecuador and northern Venezuela of northern South America.[1][2] They grow 20 to 60 inches (51 to 150 cm) long.


Milk snakes have smooth and shiny scales and their typical color pattern is alternating bands of orange-black-yellow or white-black-orange. [1] However, red blotches instead of bands are seen in some populations.[1] Some milk snakes have a striking resemblance to coral snakes and this mimicry (known as Batesian mimicry) likely scares away potential predators.

Across the wide range of this species, habitat varies. Typically, milk snakes live in forested regions, however, in some regions they can be located in open prairies. In various parts across its distribution, milk snakes often abide in rocky slopes.

However, the Eastern Milk Snake (L. t. triangulum) does not resemble a coral snake; instead it tends to have similar markings to that of several other snakes, particularly the fox snake, scarlet snake and most importantly, the Massassauga rattlesnake. Both fox and scarlet snakes are killed because of a resembalance to the slightly venomous rattlesnake.

Young milk snakes typically eat slugs, insects, and earthworms.[3] Adult diet frequently includes lizards (especially skinks), and small mammals.[1] They are also known to eat birds and their eggs, frogs, fish, and other snakes.[3]
Milk snakes are much more opportunistic eaters than the fox snake or corn snake.
They have been known to consume a variety of animals including rodents, eggs, birds, reptiles, amphibians, and invertebrates. Nevertheless the diet of an adult milk snake still primarily consists of rodents. They are nocturnal eaters and are often found during the day in old barns and under wood.Milk snakes are oviparous, laying an average of about 10 eggs per clutch, although that number may vary by region.[1] The milk snake mates from early May to late June. In June and July, the female lays three to twenty-four eggs beneath logs, boards, rocks, and rotting vegetation.

garter snake beautifull snacks

The Garter snake is a Colubrid snake genus (Thamnophis) common across North America, ranging from Alaska and Canada to Central America. It is the single most widely distributed genus of reptile in North America.



There is no real consensus on the classification of species of Thamnophis and disagreement among taxonomists and sources, such as field guides, over whether two types of snakes are separate species or subspecies of the same species is common.


They are also closely related to the snakes of the genus Nerodia, and some species have been moved back and forth between genera.

Garter snakes, like all snakes, are meat eaters. Their diet consists of almost any creature that they are capable of overpowering: slugs, earthworms, leeches, lizards, amphibians, birds, fish, toads and rodents. When living near the water, they will eat other aquatic animals.

Garter snakes are widespread throughout North America. The common garter snake (Thamnophis sirtalis), is the only species of snake to be found in Alaska, and is one of the northernmost species of snake in the world, possibly second only to the Crossed Viper, Vipera berus.

The genus is so far ranging due to its unparticular diet and adaptability to different biomes and landforms, with varying proximity to water.
However, in the western part of North America, these snakes are more water loving than in the eastern portion. Northern populations hibernate in larger groups than southern ones.Garter snakes have complex systems of pheromonal communication. They can find other snakes by following their pheromone-scented trails. Male and female skin pheromones are so different as to be immediately distinguishable. However, sometimes male garter snakes produce both male and female pheromones. During mating season, this fact fools other males into attempting to mate with these "she-males".

king cobra snack

The king cobra (Ophiophagus hannah) is the world's longest venomous snake, with a length up to 5.6 m (18.5 ft).[1] This species is widespread throughout Southeast Asia and parts of India, and is found mostly in forested areas.



can deliver a large quantity of highly potent venom in a single bite. It is one of the most dangerous and feared Asiatic snakes.


The king cobra is a large and powerful snake, averaging 3.6–4 m (12–13 feet) in length and typically weighing about 6 kg (13.2 lb). A particularly large specimen was kept captive at the London Zoo, and grew to 5.7 m (18.8 ft) before being euthanized upon the outbreak of World War II.[3] Despite their large size, king cobras are fast and agile.


The skin of this snake is either olive-green, tan, or black, and it has faint, pale yellow cross bands down the length of the body. The belly is cream or pale yellow, and the scales are smooth. Juveniles are shiny black with narrow yellow bands (can be mistaken for a banded krait, but readily identified with its expanded hood). The head of a mature snake can be quite massive and bulky in appearance, though like all snakes, they can expand their jaws to swallow large prey items.

The king cobra is the sole member of genus Ophiophagus, while most other cobras are members of the genus Naja. They can be identified from other cobras by size and hood marks. King cobras are larger than other cobras, and the stripe on the neck is like the symbol "^" instead of a double or single eye(s) shape that may be seen in most of the other cobras. A foolproof method of identification if the head is clearly visible is the presence of a pair of large scales known as occipitals, at the back of the top of the head.

Range of the Black Mamba
The black mamba (Dendroaspis polylepis) is the longest venomous snake in Africa, averaging around 2.5 meters (8.2 ft), and sometimes growing up to 4.3 meters (14 ft).



Its name is derived from the black coloration inside the mouth; the actual color of the skin varies, from dull yellowish-green to a gun-metal gray. It is the fastest snake in the world, capable of moving at 4.5 to 5.4 metres per second (16–20 km/h, 10–12 mph).


The snake's scientific name is Dendroaspis polylepis: Dendroaspis meaning "tree asp" and Polylepis meaning "many scaled." The name "black mamba" is given to the snake not because of its body color but because of its ink-black mouth.[1] It displays this physical attribute when threatened.

The black mamba's back skin color is olive, brownish, gray, or sometimes khaki in color.[3] The adult black mamba's length is on average 2.5 meters (8.2 ft),[1] but some specimens have reached lengths of 4.3 to 4.5 meters (14 to 15 ft).[3] Black mambas weigh on average about 1.6 kilograms (3.5 lb).


The black mamba is the second longest venomous snake in the world, which is only exceeded in length by the king cobra.[3] The snake also has an average life span of 11 years in the wild
The black mamba has adapted to a variety of climates ranging from savanna, woodlands, rocky slopes, dense forests and even humid swamps of Africa.[4] The grassland and savanna woodland/shrubs that extend through central, eastern and southern Africa are the black mamba’s typical habitat.[4] The black mamba prefers more arid environments such as light woodland, rocky outcrops, and semi-arid dry bush country.

puff adder snake bite

Common names: puff adder,[2][3] African puff adder,[4][5] common puff adder.[6]
Bitis arietans is a venomous viper species found in savannah and grasslands from Morocco and western Arabia throughout Africa except for the Sahara and rain forest regions.



Its wide distribution, common occurrence, large size, potent venom, and willingness to bite make it responsible for more fatalities than any other African snake.[3][8] Two subspecies are currently recognized, including the nominate subspecies described here.[



The average size is about 1 m in length and very stout. Large specimens of 190 cm (75 in), weighing over 6.0 kg (13.2 lbs) and with a girth of 40 cm (16 in) have been reported. Specimens from Saudi Arabia are not as large, usually no more than 80 cm in length. Males are usually larger than females and have relatively longer tails.

The head has a less than triangular shape with a blunt and rounded snout. Still, it is much wider than the neck. The rostral scale is small.

The color pattern varies geographically. The head has two well-marked dark bands: one on the crown and the other between the eyes. On the sides of the head, there are two oblique dark bands or bars that run from the eye to the supralabials.
This is overlaid with a pattern of 18–22 backwardly-directed, dark brown to black bands that extend down the back and tail. Usually these bands are roughly chevron-shaped, but may be more U-shaped in some areas. They also form 2–6 light and dark cross-bands on the tail. Some populations are heavily flecked with brown and black, often obscuring other coloration, giving the animal a dusty-brown or blackish appearance.

African puff adder snack

Gordon "Gordo" Fraley was born in Atlanta, Georgia. Large and strong but not very bright, Puff Adder is a mutant with the ability to inflate, or "puff," his body mass, enhancing his strength greatly, he is a dangerous adversary for several super heroes. He also has the power to breathe out toxic gas.



As a member of the fourth Serpent Squad, Puff Adder attempted to rob a Las Vegas casino, and battled Captain America, the Falcon, Nomad, and D-Man.[1] With the Serpent Squad, he was freed from jail by Sidewinder.[2] Puff Adder was inducted into the second incarnation of the Serpent Society as a double agent of the Viper during her invasion of the group. Puff Adder and the Viper's agents then betrayed Sidewinder, and encountered Captain America again.


Alongside Anaconda, Puff Adder served as bailiff at the Serpent Society's trial of Diamondback. With Anaconda and Rock Python, Puff Adder was sent to Diamondback's apartment to apprehend her. He battled Captain America and seemingly overpowered him.[5] Puff Adder crash-landed a Serpent Saucer on Diamondback's apartment. He abducted Diamondback, Asp, and Black Mamba. Rock Python and himself were thrown from the Serpent Saucer by MODAM, and Puff Adder was injured in the fall. He was interrogated by Captain America and Paladin about the abduction of Diamondback and her friends.

After a brief fight, both teams are overwhelmed with alien doubles of absolutely everyone involved. Out of necessity, the two teams work together to destroy wave after wave of doubles. After the last wave, Doctor Octopus wants his team to continue fighting but Puff Adder, along with the rest, turn on him. They do not want to hurt the others who just helped save their lives. The team chases Doctor Octopus out of the mansion.


He appeared in Brand New Day as one of the villains in the "Bar With No Name". He is one of many to get in on the super-hero related gambling action headed by the man known only as 'The Bookie'.[10]
His race varies from artist to artist. In his first appearance, he was depicted as Caucasian, but a few issues later, he is depicted as African American.
