"MALAGASY GIANT HOGNOSE SNAKE".
The hognose snake is a type of colubrid snake characterized by an upturned snout. They are notorious for playing dead when threatened. The hognose snakes consist of three distantly related genera that are artificially grouped together by the "hognose" common name: Heterodon which are predominantly found in United States and northern Mexico. Leioheterodon the Madagascar hognose snakes, and Lystrophis the South American or tri-colored hognose snakes.
Hognose snakes (Heterodon) are rear-fanged and technically venomous, but the venom they excrete is not considered to be dangerous to humans and they will never bite in defense (as the only way to get bitten by a hognose snake is to smell like their prey). There has been some debate whether or not hognose are venomous, but there is evidence that their saliva has some toxicity to smaller prey items, such as toads and frogs. The fangs have been referred to as just "enlarged teeth", but they are genuine fangs that are used for venom delivery and also prey restraint. Despite the common belief, there is no evidence to support the fangs being used for "toad popping". Under this belief, the toads inflate their lungs to make swallowing difficult, but the fangs would penetrate the lungs and deflate them. However, whole toads with intact lungs are commonly regurgitated by recently captured hognoses.
When threatened, hognose snakes will flatten their necks and raise their heads off the ground, not unlike a cobra, and hiss. They may sometimes feign strikes, but are not apt to bite. This behaviour has earned them several nicknames, such as "puff adder", "blowing adder", "flathead", "spreadhead", "spreading adder" or "hissing adder". Note, though, the nickname "puff adder" is only a nickname, and is not scientifically correct. There is a highly venomous viper from Africa called the puff adder, Bitis arietans.
If this threat display does not work to deter a would-be predator, hognose snakes will often roll onto their back and play dead, going so far as to emit a foul musk and fecal matter from their cloaca and let their tongue hang out of their mouth, sometimes accompanied by small droplets of blood. If they are rolled upright while in this state, they will often roll back as if insisting they really are dead. It has been observed that the snake, while appearing to be dead, will still watch the animal that caused the death pose. The snake will 'resurrect' sooner if the threat is looking away from it than if the threat is looking at the snake. |

Hi, dear friend.
You fill up your collection so quickly and I like all of your shots. This one is not exception. You have reflected this beauty very nicely. Coloration, texture and shapes are reproduced precisely. Lights are very good too and note (as usual) is complete and interesting. My warm regards and compliments.
Alexei.
Hi Mario,
The snake looks like it is rather big. Sharp focus on the head and the body. Good framing and very well exposed shot.
TFS and best regards,
Jusni

Hello Mario !
Impressive picture of this snake, I really like it - it's a beautiful species, and captured with nice details on the scales. Maybe one could reproach that the focus is not on the head, but not such a big problem for me, as it is a very inteesting picture and the note going with it was great to read, too. Very well done !
Valérie.
