There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

Lachesis muta
It is a venomous pit viper species found in South America, adults grow to an average of 2 to 2.5 m (6½-8 feet), although 3 m (10 feet) is not too unusual. The largest recorded specimen was almost 3.65 m (12 feet) long, making this the largest of all vipers and the longest venomous snake in the western hemisphere. Lachesis muta is the third longest venomous snake in the world. A individual 2,24 m weighted 4 kg, this species is estimated to weight from 3 to 5 kg (6.6 to 11.0 lb), somewhat less than the heaviest rattlesnakes or Bitis vipers. The color pattern consists of a yellowish, reddish or grey-brown ground color, overlaid with a series of dark brown or black dorsal blotches that form lateral inverted triangles of the same color. The lateral pa ttern may be precisely or indistinctly defined, normally pale at the center.
Found in South America in the equatorial forests east of the Andes: Colombia, eastern Ecuador, Peru, northern Bolivia, eastern and southern Venezuela, the island of Trinidad in the Republic of Trinidad and Tobago, Guyana, Surinam, French Guiana and much of Brazil. Some reports suggest that this species produces a large amount of venom that is weak compared to some other vipers.

Micrurus mipartitus (redtail coral snake)
It is a species of coral snake in the family Elapidae. It is found in South America and Central America. The redtail coral snake is common in areas very close to Caracas, Venezuela, Its highly neurotoxic venom is known to cause seizures in its prey by activating nerve proteins responsible for seizures within it, here in Venezuela it is the snake with the most powerful venom, it is a very calm snake that only bites if you hold it and the big problem with it is that we do not have antivenom for this snake in Venezuela and if it bites the person will die for sure in a short time.
The M. mipartitus has a cylindric body that can reach up to 1.22 meters in length but normally measure from 60 to 80 cm long. They have quite small eyes upon their round heads. The rings of this species can range anywhere from 34-84 black bodily rings that are sundered by yellow or white intermediaries. The second ring on the head and 3 or 4 of the tail rings exude a red color in contrast to the white or yellow bands.

Bothrops
is a genus of pit vipers endemic to Central and South America. The generic name, Bothrops, is derived from the Greek words βόθρος, bothros, meaning "pit", and ώπς, ops, meaning "eye" or "face", together an allusion to the heat-sensitive loreal pit organs. Members of this genus are responsible for more human deaths in the Americas than any other group of venomous snakes. These snakes range from small, never growing to more than 50–70 cm (19.5–27.5 in), to large at over 200 cm (6.6 ft) in total length. Most are characterized by having a sharp canthus rostralis and an unelevated snout.
Common names: the name "lanceheads" to all of these snakes, which he considered conspecific. Thus, older writings, as well as popular and sometimes scientific writings (including the American Heritage, Merriam-Webster, and New Shorter Oxford dictionaries), still often call them fer-de-lance (French, "iron of the lance"). Other common names include American lanceheads and American lance-headed vipers. Most species are nocturnal, although a few found at higher altitudes are active during the day. Otherwise, they may be seen on cloudy days or during periods of rain. Most are terrestrial, though all are capable of climbing.

Bothrops
Typical symptoms of bothropic envenomation include immediate burning pain, dizziness, nausea, vomiting, sweating, headache, massive swelling of the bitten extremity, hemorrhagic blebs, local necrosis, bleeding from the nose and gums, ecchymosis, erythemia, hypotension, tachycardia, coagulopathy with hypofibrinogenemia and thrombocytopenia, hematemesis, melena, epistaxis, hematuria, intracerebral hemorrhage and renal failure secondary to hypotension and bilateral cortical necrosis. There is usually some discoloration around the bite site, and rashes may develop on the torso or the extremities.
In general, death results from hypotension secondary to blood loss, renal failure, and intracranial hemorrhage. Common complications include necrosis and renal failure secondary to shock and the toxic effects of the venom. The big problem with Bothrops is that they are not like Rattlesnakes which makes a loud rattling noise when vibrated that deters predators or serves as a warning to passers-by, if a person passes by a Bothrops it will strike an bite injecting venom for sure.

The Gaboon viper is a viper species found in the rainforests and savannas of sub Saharan Africa.  Like all vipers, it is venomous. It is the largest member of the genus and it has the longest fangs – up to 2 inches in length (5 cm) – and the highest venom yield of any snake
Adults average 125–155 cm (4 to 5 feet) in total length with a maximum total length of 205 cm (81 in) for a specimen collected in Sierra_Leone. The sexes may be distinguished by the length of the teeth in relation to the total length of the body: approximately 12% for males and 6% for females. Adults, especially females, are very heavy and stout.

Reptile: What do we have here...?

Gastropod: Yooo!!! get outta my way.

Reptile: It looks so creepy, let's give it a try...

Gastropod: Said what???

Reptile: yom yom yom... it's like chewing gum.





Its tentacles are moving inside snake's mouth... eww yuck disgusting... Ha Ha
See how the snake is making the snail to come out of its shell to swallow like sucking. In the middle of video, head of the squamate is almost doubled. This type of snakes swallow their prey whole and alive. Thanks to mechanism of breathing from two holes and they can hold their breathe for certain time during swallowing and swimming under water. Snakes have two ways of breathing. The first is their nostrils, second is the glottis. When swallowing prey, the snake will push it's glottis, which is a tube leading to their lungs, out of their mouth so they can breathe.

Snakes would have a pretty hard time choking coz during this peristalsis, the food exerts some pressure on respiratory tract too. Some of the fewest animals that eat or swallow underwater.

Gargi Biswas
The deadliest encounter!

Cobra versus Russell's Viper 

14th of December, 2018
IIT Kharagpur Campus, Kharagpur, West Bengal

*This image is copyright of its original author

Gargi Biswas "For those who are interested in knowing the outcome/result of this deadly encounter, here is the story. One afternoon I found a Russell's Viper lying still on the road at IIT Kharagpur Campus. It was not moving at all and looked almost lifeless.Suddenly I saw a Cobra coming out of the nearby bushes. It came very close to the Russell's Viper and then went back. After few seconds, it came back again and initiated a fight with the Viper. Definitely the Cobra looked more aggressive and fierceful. The Cobra did attack the Viper as can be seen in this pic. The Russell's Viper retaliated. Exactly, at this point in time, a truck came from the back. The Cobra vanished into the bushes again. Both parted.So in the literal sense of the term, there is no winner or loser in this battle. As, I watched them, I got goose pimples and definitely my heart beat went faster than usual."

Photo @tbfrost | This is the black mamba of the Amazon, only it is *not* venomous. This deep red-colored snake is the rusty whip snake (Chironius exoletus), considered a warrior of the rainforest by herpetologists for its speed, agility, and boldness. Scientists tell me they almost always find this particular species with scars or fresh wounds, a testament to battles it has endured. Thing is, this snake, as with all snakes, doesn’t have an interest in hurting humans , which is evident here as it is resting calmly in the hands of Lucas M. Bustamante, a scientist and photographer with Ecuadorian nonprofit @tropicalherping. This snake was caught as part of an ongoing, and fully permitted, scientific project. If you see a snake, leave it alone; it's better for you and the snake.
