Abstract: The purpose of this communication is to examine and compare blood vessels outgoing from and incoming to the heart and lungs in two individuals snake from species – boa and corn snake, which are not poisonous, desirable pets and often require veterinary care. Two female snakes were used, for which the major arterial and venous blood vessels were followed through precise macrodissection and radiography after injection of barium sulfate in the dorsal aorta. Significant difference was confirmed in the branching of the left and right aorta in the comparison between the two individuals snake from two species. The variation of the carotid artery and the ramification from it were followed in the boa, while in the corn snake highly developed right jugular vein was observed. Blood vessels in reptiles are very interesting for the variation anatomy, comparative zoomorphology and veterinary practice in surgical interventions on these animals.
Key words: reptiles, boa, corn snake, common carotid artery, jugular vein.
Introduction
Reptiles are widespread and their share as home-grown animals increases immensely, especially snakes of the Boidae

The owners of the first snake noticed non-specific aggressive behavior and torticollis pointing towards nervous disorder; treatment was appointed without a clear improvement, and the outcome was fatal. The second snake had a loss of appetite, apathy and lethargy; again despite assigned treatment lethal outcome was observed. Because of nonspecific pre-mortem symptoms these animals were admitted at the University Clinic of the Faculty of Veterinary Medicine, University of Forestry, Sofia for expert autopsies. Precise macrodissections were performed, which did not identify clear, visible pathological

Other large non-native snakes— such as the common boa (Boa constrictor), green anaconda (Eunectes murinus), yellow anaconda (Eunectes notaeus), and reticulated python (Python reticulatus)—have been observed in the wild in South Florida, but only Burmese pythons and common boas are known to be breeding. Burmese pythons were first reported as established in Everglades National Park (ENP) by Meshaka, based in part on specimens collected on the Main Park Road in the mid-1990s. Since then, the number of Burmese pythons captured or found dead in and around ENP has dramatically increased. From 2002 - 2005, 201 pythons were captured and removed or found dead.
The point I am trying to prove here is, Sykes would always want to scare Delia with a snake, the first time it was with the bull whip and the last night Sykes put the snake in the soap box to scared Delia to death. Little did Sykes know Delia had faced her fears and learned how to overcome of the snakes. Towards the end of the story when Sykes was supposed to be the master of catching Snakes, the rattle snake makes a transparent sound and bites Sykes. He wanted to scare Delia lifeless but his plan back fired on him.

Natural predators of the snake haven't been cited in the Everglades. As a result, its wiped out huge numbers of possums, raccoons, bobcats, and many bird species. The newspaper
They are not poisonous, instead they are constrictors, meaning they suffocate their prey before swallowing them whole. Most snakes leave their young to fend for themselves. Also, because they are constrictor, they don’t have fangs. Snakes don’t eat every day. They spend most most day sitting in the sun. A Burmese Python’s jaw can unhinge, so it can swallow things that are four to five times as large as its head. When It digests its food, its guts and everything needed for digestion grow. When the snake is done digesting, the system returns to its normal state.

The story Jurassic Park, by Michael Crichton, starts off with Mike Bowman taking a vacation with his family on the coast of Costa Rica. As they cruise on their Land Rover, Tina, Bowman’s daughter, runs off after spotting three-toed bird tracks. Tina then encounters a big lizard that makes chirping sounds, and is attacked by it. She is later sent to the hospital, where Dr. Gutierrez is intrigued to find out about the lizard that bit her left arm. Gutierrez goes back to the beach where Tina was attacked, and finds the carcass of a brown-striped lizard. The carcass is sent to the Tropical Diseases Laboratory of Columbia University Medical Center, where it is examined and analyzed. Despite the efforts made, no one is able to identify the lizard’s species, so the carcass is later sent to the Museum of Natural History for further analysis.
Biodiversity is the variation and amount of species across the globe, or within in a specific geographical habitat. There are three different areas of study within biodiversity; ecological diversity, species diversity and, genetic diversity. Science Book Species diversity is the variety of different organisms and relationships within a specific species, this essay will discuss the declining of species diversity among sea turtles and the implications it has on the worldwide seas. I have chosen to research about the topic because, sea turtles are believed to have been alive during the Jurassic period. However, now all seven sea turtle species are critically endangered or vulnerable, due to human activities such as; commercial fishing, bycatch and, climate change. (WWF, OCEANA, ACTIONBIOSCI)
Condition: Mostly intact, with the base chipped from the thumb across the back of the hand to the ring finger. There is also a fragment missing under the snake on the back of the hand, below the middle and ring finger. The artefact shows signs of corrosion as it has turned dark green in colour. It has also lost its sheen. Details of the fingers and outline of the snake coiled around the wrist appear to be worn down.

The first step was to obtain the White Rat and to tie it in the supine position, anterior surface facing up in side the dissection pan. To tie the animal, we used butcher’s twine and secured the front and hinds legs using a “lasso” technique, careful not touch the sharp claws. To make the first insicion I had to locate the Xifoid Process of the rat (distal aspect of the sternum). Once I had located the Xifoid Process, I had to use forceps to pull the skin of the animal’s abdomen up and use the scissors to cut. The first incision is made from stem to sternum, cutting through the errectos abdomen muscle down to the groin. The second incision ion is perpendicular to the first below the diaphragm. Because of this technique we were able to open the abdominal cavity first. The third and forth incisions were made bilaterally above the legs. The last two incisions were made in upside down “V” shape on the collarbone, to expose the thoracic cavity. This dissection was both sharp, because of the use of the scissors and scapel and blunt because of the use of the probe and forceps to move organs and skin to expose other organs not yet identified.
