In this world various types of species live on planet earth, each with a specific way of living and adapting to the climates of the Earth. Two of the type of animal groups are mammals and reptiles. Each animal has many different charatistics and some alike.
Mammal and reptile have inhabited the earth for millions of years now. Both are oxygen-breathing vertebrates that need nourishment for living. Mammals and reptiles are both tetrapod’s which means they both have four legs.
Mammals give birth to live offspring. Most offspring that completely dependent on their mother for finding their food and nourishment for the beginning part of the life of the offspring. Mammals also can regulate body heat. Also, they have a jaw made from a single bone

and a middle ear. Mammals also include the largest animals on the planet. Some mammals are adapted to life at sea, in the air, in the trees or on two legs. A mammals body usually consists of hair, and are warm blooded, they primarily nourish their young with milk. Diets include herbivores, carnivores, and omnivores. Some examples of mammals are cows, horses, apes, beavers, whales and dolphins. Reptiles are vertebrates and are mostly egg laying creatures, there are some reptiles that do give live birth to offspring like the viper snake.
The eggs of reptiles are very protective and have a hard outer shell that protects the embryo from harm. Most reptiles are carnivores that have a slow digestion and metabolic rate. Reptiles are cold blooded animals and usually are covered in scales. The scales protect their bodies from harm. Some reptiles are born on land and are born with strong instincts, so they are on their own at birth. Being cold blooded reptiles they cannot regulate body heat and depend on warmth from the sunlight to become warm, if they become too hot finding shade and a place to cool down is vital. Some examples of reptiles are frogs, crocodiles, snakes, and turtles.
The difference between mammals and reptiles, are mammals give birth to their offspring live, while reptiles lay eggs. The mammal offspring is very dependent on parents for protection while reptiles do not need their parents in order to survive. The main difference between mammals and reptiles is how they regulate body heat, mammals are warm blooded while reptiles are cold blooded. Moreover, mammals consist of hairs and furs while reptiles have
scales. Mammals and reptiles may have different charatistics but each play an important role in a healthy ecosystem and co-exist well. Each animal has a vital impact on the ecosystem and on the circle of life.
The differences are due to the differences in environment, habits, size etc. One example is the fact that minks and humans both have lugs of similar shape but different lobes. Each of these similarities and/or differences benefit both the human and the mink, in their own unique way, with each structure having its own function. Overall, the mink is a very complex animal and so is an individual.
Animals differ in their abilities to regulate body temperature (thermoregulation). We sometimes use the terms "cold-blooded" or "warm-blooded." Most reptiles feel cold to the touch, while mammals and birds often feel warm.
...nted muscles. The quadrupling of genes led to bigger animals such as elephants. The largest member of the chordate phylum that ever walked on Earth was dinosaurs. The closest animal relative to humans is great apes. Great apes can think, feel, nurture own kind, pass on social skills, mimic, and remember just like humans do. Human intelligence is greater than anything on Earth! This video enhanced my understanding on Chordates because it explains how some chordates are or are not vertebras and it showed how land animals evolved from fish. I always like to see different videos on how species originated, especially humans.
Throughout the animal kingdom, adaptations take place continuously and even the smallest of changes can leave a significant impact. Examples can be seen within any plant or animal. One example would include sea turtles, specifically, the Loggerhead Turtles. These turtles are native to the Indian, Atlantic, and Pacific Oceans as well as the Mediterranean Sea (Deurmit L 2007). They thrive in either temperate or tropical climates and can live in a myriad of biomes (Deurmit L 2007). These biomes include the pelagic, reef, coastal, and brackish water (Deurmit L 2007). Loggerhead turtles are omnivores and can eat anything from insects to aquatic crustaceans, to macro algae (Deurmit L 2007). According to Deurmit (2007) Caretta caretta is classified into Animalia Kingdom, Chordata Phylum, Vertebrata Subphylum, Reptilian Class, Testudines’ Order,

The descendants of the first radiation of mammals, monotremes have characteristics of both placentals and marsupials, while still retaining characteristics of reptiles and birds in a combination all their own. Introduction At first glance, platypuses seem to be an amalgamation of mammals, birds, and everything in between. In fact, their reproduction biology also has much in common with a variety of animals—reptiles, birds, placentals and marsupial mammals. Platypuses belong to a group of animals called monotremes. These egg-laying mammals have been a mystery to researchers since their discovery by Westerners over 200 years ago.
5.) Primates and all mammals share a series of characteristics such as: body hair, long gestation and live birth, mammary glands, different types of teeth, ability to maintain a constant body temperature, increased brain size and a considerable capacity for learning. Scientists created a special order called primates, because they share many characteristics unique to their order: a tendency toward erect posture, a flexible, generalized limb structure, hands and feet w/ a high degree of apprehensibility, retention of 5 digits on hands and feet, an opposable thumb, nails instead
How do reptile scales differ from fish scales? (2 points) A reptiles scales are in the epidermis of the skin whereas a fish’s scales are in the dermis of the skin which is located underneath the epidermis. All reptilian scales have a dermal papilla underlying the epidermal part.
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)
...that has to be more than just watching. That difference is the brain. For example, the chimpanzees brain is way larger than the human brain. Another difference between a chimpanzee and a human is the able to be in water. Most all humans like to be in water and can swim and chimpanzee are deeply terrified of the water and can not swim (Morris).

Turtles have existed for a very long time. They have existed for about 215 million years. Turtles have been alive a lot longer than mammals,crocodiles,birds,snakes and lizards. They can live up to about 200 years but most live until they are in their mid 70s. Turtles have a hard shell that protects them like a shield. This upper shell is called a carapace.The lower shell called a ‘plastron. The shell is attached to their spine and lower ribcage. It is different from other animal’s shells like the crab. The turtle’s shell is permanent, it cannot come off.

What is a dolphin? A dolphin is an aquatic mammal. There are a various amount of species of dolphins,who eat a large variety of food,and can live in several different environments.
