Spiders are air-breathing chelicerate arthropods that have two body segments, eight legs, and no chewing mouth parts. About 40,000 species have been identified. In spiders' bodies the usual arthropod segments are fused into two tagmata, the cephalothorax and abdomen, joined by a small, cylindrical pedicel. Redback spider The Redback spider is a potentially dangerous spider which lives in Australia. It resembles a Black widow spider.
A single bite from a Black Mamba contains venom with the abilities of killing anywhere from 10-25 adults. The average bite releases about 100–120 mg of venom, although it has the abilities to administer up to 400
Tarantulas may seem scary, but they are just like any other spider. A tarantula can vary in size, color, and other physical features. The average size of a tarantula is two to three and a half inches, and an average leg span of five to ten inches long. The eight legs of a tarantula are what make the spider look so big. The tarantula can get up to the size of a plate.
It is a big lizard because it grows to a length of 18 to 24 inches. Gila monsters are in the Heloderma species. They live in Nevada, Arizona, California, Utah, Texas and New Mexico. They run from 4 meters a minute to 15 meters a minute. They are also diurnal.
In order to withstand cold temperatures, the diamondback rattle snake hibernates during the winter months in underground boroughs previously made by other animals as it does not have the ability to dig on its own (Glaudas, 2009). To protect it self from hot weather, the diamondback becomes nocturnal in the summer months and consumes its meals at night when the temperature becomes cooler. Therefore, it is most active during the spring and fall months when the weather is most ideal. The diamondback rattlesnake has the ability to slow its metabolic rate to reduce the amount of food, water and oxygen it needs to survive (Glaudas, 2009). The diamondback rattlesnake’s skin is also another example of how this organism has adapted to living in the Southwestern desert.
[6] In the wild, Burmese pythons grow to 3.7 metres (12 ft) on average,[3][4] while specimens of more than 4 metres (13 ft) are uncommon. [7][8] In general, individuals over 5 metres are rare. [7] The record maximum length for Burmese Pythons is held by a female named “Baby”, that lived at Serpent Safari, Gurnee, Illinois, for 27 years. Shortly after death, her actual length was determined to be 5.74 metres (18 ft 10 in). Widely published data of specimens that were reported to have been even several feet longer are not verified.
In the United States, there are over 30,000 mountain lions (“Basic facts”, 2014), which makes this cat the largest member of the cat family present in the country (“Mountain Lion”, 2014). However, the Florida panther is very endangered with less than 100 living mountain lions still roaming (“Basic facts”, 2014). In Colorado, there is a high mountain lion density with one cat for every eight square miles (Busch, 1996, p.46). This cat is found in typical mountain regions, swamps, and also
These SPINES were probably embedded in a thick ridge of muscle. Acrocanthosaurus is the only known American dinosaur with such high spines. It is known from a skull and most of a skeleton found in Oklahoma and Texas. A recent flood in Texas uncovered some footprints that scientists think were made by Acrocanthosaurus. AcrocanthosaurusFOSSILS have been found in similar rock hearby.
4. The katydid has four good sized wings that fold over the back. 5. The katydid, like all insects, has a head, thorax and abdomen. Adaptations: 1.
The parietal bone is elongated and compressed, as opposed to the rounded human parietal bone. 3. Compare the shape and position of the occipital bones in the human and chimpanzee skulls. How does the difference in the position of the foramen magnum, a large opening in the base of the skull for the spinal cord, correlate with the posture and stance of the two organisms? The occipital in humans is rounded; in the chimpanzee, it has a prominent ridge for attachment of neck muscles.
