Sea turtles are ancient creatures. They have been around for more than 110 million years ago. Turtles can live up to 100 years old fi they are able to protect themselves from harm. The Latin name for a sea turtle in general is Chelonioidea. Sea turtles are classified in following: Animalia Kingdom, Chordata phylum, Repitila class, Testudines order and Crypotdia suborder. They are also classified in the Chelonlidae or Dermochelyidae family. The genus and species of sea turtles depends on the species it is. There are seven species of sea turtles which are Green turtles, Logger head, Leatherback, Hawksbill, Olive Ridley, Kemp’s Ridley and Flatback. Stated by National Wildlife Federation (NDF), Green turtles are rarely seen on land. Since they …show more content…
They are one of the few creatures to have an internal and external skeleton. Their external skeleton is for protection for their internal organs. It has two halves called lower plastron and upper carapace. The carapace is known as the turtle’s shell. It covers mostly everything except their flippers and head. Not every turtle has a green shell. Their scute is a bony external plate on the shell of the turtle. The scute is used to determine what species a turtle is by counting the number of species they have. Green Sea Turtles are large they range around 5 1/2 feet and can weigh up to 400 pounds. People wonder how they got their name, it is from the color of their fat. Their fat is that color because they consume …show more content…
Except they have cloacas. Cloacas is “a common cavity at the end of the digestive tract for the release of both excretory and genital products in vertebrates.(Dictonary.Refrences)” They have two regions in their stomachs named The cranial region and caudal fundic pyloric region. Thye also have three regions of their small intestine, the duodenum, jejunum and ileum. The excretory system of the turtle is where all harmful wastes from the turtle's body and blood are removed. The kidney sends wastes to the bladder as urine. It does this because the kidney performs blood filtering. The bladder stores the
In the Grapes of Wrath, a novel by John Steinbeck, there are many examples of symbolism. One of the most prominent symbols found in this book is the turtle seen in chapter three. This turtle is symbolic of three things: the Joads and their journey west, Tom Joad himself, and the promise of new life. First, here’s a little background information on the turtle. This land turtle was somewhere to go. Where than is, no one knows, except perhaps John Steinbeck. To get there the turtle decides to take the perilous journey down a dusty dirt road that stretches along the quiet countryside. What could happen? A lot more than one might think. In fact, the turtle faces quite a few challenged ranging from pesky insects, to ledges, to even cars. But, the thing that makes this turtle special is that he never gives up (Pages
Manatees, commonly called Sea Cow, are large aquatic mammals that are found in warm coastal areas, rivers and warm water springs in the Amazon Basin, West Africa, the Gulf of Mexico, the Caribbean Sea and the Southeastern United States. Manatees can be found in salt water, fresh water and brackish water. They spend most of their time eating aquatic plants, resting, migrating and nurturing their young. The manatee species has evolved over the last 45 million years. The adult manatee evolved into an average of approximately 10 feet long and weighs between 800 and 1,200 pounds (Site This).
The green sea turtles have been taken out of the Atlantic Ocean for several years, so now they are an endangered species. Today, the green sea turtles population is growing and in the Florida Refuge they counted up to over 12,000 turtle nests. It is shocking to see how much the refuges care about the green sea turtles. They have been looking out for the turtles for 35 years. It was interesting to find out that these green sea turtles live for a really long time. It takes the turtles 25 years just to mature. This article caught my eye because I love science and animals. Knowing that people are taking care of what used to be endangered animals really means a lot to me. I hate seeing animals hurt or struggling to survive. Because of the refuges
The Florida Manatee’s popular marine species in the tropical environment of Florida are currently considered an “endangered species”. The ecology (the relationships between living organisms and their interactions with their natural or developed environment), for the manatee (trichechus manatus), requires and is generally restricted to the inland and coastal waters of peninsular Florida during the winter, when they shelter in and/or near warm-water springs, heated industrial effluents, and other warm water sites (as stated in Research Gate (1997) Hartman 1979, Lefebvre et al). The Florida (West Indian) Manatee, An Endangered Species, has no known predators other than humans; in the past, humans hunted
First, it’s important to check in and see if YH is confident in her ability to adopt the new behaviour, if she lacks confidence the behaviour change is less likely. If her confidence is lacking, it’s vital to re-assess the appropriateness of the intervention for YH. For example, I might consider that the ‘turtle’ image might not be working. The original authors mentioned that for third or higher grades, children may not respond well to the turtle image and other ‘more mature’ images are desirable. It doesn’t matter what the image is, just how it is used. Any vivid image can serve as the metaphor for this self-control response intervention. Lastly, adjust therapy specifically to her, write social stories (or modify the turtle story) about individual anger management, what are her ‘triggers?’, and are there any new responses she needs to practice?
Sirenia: Trichechidae (the manatee) is a large, mostly herbivorous, aquatic mammal. Manatees are often referred to as “sea cows.” There are three recorded species of manatees: the Amazonian manatee “Trichechus inunguis,” the West Indian manatee “Trichechus manatus,” and the West African manatee “Trichechus senegalensis.” There is also the Trichechus pygmaeus (The dwarf manatee). This species has yet to be validated. I live in Florida where the manatee can be found throughout Florida’s abundant warm water locations. Manatees reside in warm water, shallow rivers, bays, estuaries and coastal waters. (Google, 2014)
We all have a special sort of love for someone, or something in our life. Well in my case, turtles are what I have a special love for in my life! I have always liked them, ever since I was a little kid around the age of about four or five. The show “Franklin and Friends” would come on and I would be connected with my TV screen until the end of that show, I mean connected! So on with how I like turtles so much!
The Blanding’s turtle is identified by its unique appearance. Its top shell is a round, dome shape unlike other turtle species. The top shell is black with characteristic yellow or tan spots, and the under shell is a light yellow with characteristic brown spots. The neck and throat are a bright yellow, making it easy to identify from other turtles species. Adult males can reach lengths of 11 inches, and females can reach lengths of 8.5 inches. They are relatively medium-sized, and often nicknamed the “semi-box” turtle because they are physically similar to the box turtle.
Introduction Caretta caretta, otherwise known as the Loggerhead Sea Turtle, is an oceanic turtle that exist throughout the globe. They are circumtropical species (LeBlanc et al. 2014) meaning they are distributed throughout temperate and tropical ocean regions, but most abundant species are found in the United States coastal range. Loggerheads largest nesting aggregations in the Atlantic are found along the southeastern United States coastal range where about 80% of all nesting occurs and 90% of all hatchlings are produced (Abecassis et al. 2013).
Imagine being able to have a turtle in your classroom that can live up to 150 years! A turtle would be a more acceptable class pet due to the fact that there is a variety of turtles to choose from. For instance, you could have a land turtle which can easily be taken care of since they are herbivores. Land turtles can also live for about a year without water since they get all their water from the plants they consume. Lastly, land turtles can also live up to 150 years, which can be beneficial if you don't want to be spending your money every once in a few years on getting another pet.
In the original listing from USFWS (1978), the loggerhead sea turtle was listed as threatened throughout all of its range. The document goes on to state that one of the main threats to the loggerhead sea turtle was that it was being harvested for the shell or as food; the eggs were considered a desired food item and protein source. Regulations were put in place to protect the loggerhead sea turtle such as prohibition of foreign commerce, importation, and exportation (USFWS 1978). One factor that is considered a past threat was the inadequacy of any existing regulations regarding the loggerhead sea turtle (USFWS 1978). Since the listing of the loggerhead sea turtle, many regulations and recovery plans have been made. However, many of the threats described in the loggerhead sea turtle listing of 1978 are still threats that are present today. These threats include human expansion reducing nesting habitat through beach development including artificial light and seawall construction, disease, and predation of hatchlings (USFWS 1978). Today the current status for the loggerhead sea turtle is unchanged and they remain listed as a threatened species (NMFS and USFWS 2007). This was determined in the most recent 5 year review using molecular markers to help define the genetic structure of the population (NMFS and USFWS 2007).
When you think of a marine biologist, what do you see? You might picture a dolphin trainer, or maybe you see a man swimming with whales and sharks deep in the middle of the ocean. The field of marine biology is the study of aquatic organisms, their behaviors, and their interactions with the environment. It is considered the most unknown and exciting fields of oceanography.
The pattern on the tortoise's back is often referred to as “The Star”. Due to the many shades of colors the tortoise often can appear to be the color of red or orange. The young radiated tortoises have a more white than yellow pattern. Tortoises commonly have a dark patch on top of their heads. All radiated tortoises have a high dome bumpy shell. The tortoise's shell is more pyramidal compared to normal tortoises. “ The tortoise has a average turtle shape, a domed carapace, blunt head, and the elephantine feet.” (n.a. animal diversity.org). The radiated tortoise is sometimes considered to be one of the most beautiful tortoises in the world. But as the individual's age, the darkly colored pigment washes out and creates a lighter colored
Echinoderms (scientific name Echinodermata) are a major group of only marine animals. The name comes from the Greek word for "spiny skin". There are about 7,000 species found usually on the sea floor in every marine habitat from the intertidal zone to the ocean depths (Marine Education Society of Australasia 1999-2015). They occur in various habitats from the intertidal zone down to the bottom of the deep sea trenches and from sand to rubble to coral reefs and in cold and tropical seas. Some echinoderms are carnivorous, others are detritus foragers or planktonic feeders.
Some of us might be really looking for pets that are not that ‘complicated’ and not that ‘boring’ to have. While dogs (though cute and irresistible) are a little messy to pet around and you can’t interact that much with a fish - you might be interested in petting turtles. What do you think? Turtles are definitely becoming popular as pets. They may not be that sweet, cuddly creatures but obviously, these sea animals are undeniably fascinating and the fact that it’s not that complicated to take care of, of course, if you are well informed and so ready to become a parent - might make you want to consider to have one.
