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, …show more content…
The courting ritual begins with the males circling females in an offshore mating ground and then the males approach and bite a female’s neck and if she accepts, they mate; if she does not accept, she swims to the bottom of the mating grounds (Deurmit L 2007). Males have long claws to use during mating because other males try to remove the mating male in order to mate with the female (Deurmit L 2007). Caretta caretta are polygynandrous and breed seasonally in the early summer (Deurmit L 2007). With mating, the females have the ability to store sperm throughout the reproductive season (Sakaoka K et al.). This characteristic developed with “changes in the sperm storage tubules (SSTs) in the oviduct” and allows the females to reproduce more (Sakaoka K et al.). This storage helps to combat climate change because Caretta caretta, as a species, only breed during certain temperatures (Sakaoka K et al.). Female loggerhead turtles have developed sperm storage abilities within mating to combat climate
What does one think of when the word “turtle” is mentioned? This adorable creature is usually thought of as slow, futile, and the unsung hero of “The Tortoise and Hare.” However, Kay Ryan argues in her poem “Turtle” that turtles are more than just these things: they are strong but unfortunate creatures that must put up with many obstacles in order to survive. Despite the struggles that she faces, the turtle exhibits a multitude of different strengths to overcome them, as seen as the poem progresses.
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
The poem Mark O’Connor wrote “Turtles Hatching” at a time in his life when was closely studying nature.
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 more we learn about Painted turtles and all forms of life the closer we get to understanding ourselves and the way that we came to be. Nature continues to astound us with the solutions to new problems. Within these little turtles may be the answer to cryogenics, or to frostbite. There are innumerable bonuses to every new bit of information that we learn. While we may never learn all there is to know, we can know more.
Crayfish are Crustaceans, which is a type of Arthropod. Crayfish has five pairs of legs which are jointed, counting the pinchers it has to pick up food and defend itself. The other four pairs are used for walking legs. They have a hard exoskeleton and as aforementioned, two, big pinchers. They have two small pairs or smaller antennas to sense food in the water and find a mate, while the bigger antennas are used for touch and making sure it doesn’t bump into things. They have two eyes which are on stalks so they can rotate around, and lastly they have a tail to help with steering and swimming. Crayfish will use their pinchers to catch food and also defend themselves if attacked or threatened. Crayfish are closely related to crabs, lobsters, and shrimp. Some species of crayfish are signal crayfish, red swamp crayfish, and rusty crayfish. Crayfish only live in freshwater and can live in moving or standing water. Crayfish are omnivore, so they eat both plants and animals. Most fossils records of crayfish come from the last 30 million years, but there are some
There are many types of species throughout the world, from sea creatures to land creatures. Each with different appearances and abilities to help them survive.
When sea turtles lay eggs they do so by the thousands and each turtle lays about 100 eggs multiple times throughout their lifetime. Because of predators, not all 100 eggs will get to hatch and continue their parent’s bloodline. In order to beat the odds for survival of the bloodline, each turtle lay many eggs. The sheer amount of eggs laid in a lifetime will almost assure that at least one egg will survive long enough to continue the
Hermit crabs have been reported to be capable of habituation through previous research. If hermit crabs are capable of habituation, the retraction reflex should habituate to a tactile stimulus if the stimulus is not harmful to the animal. Furthermore, if the animal does habituate, the number of presentations of the stimulus required to elicit a response should increase (Hypothesis 1), the time to re-emerge from its shell after retraction should decrease (Hypothesis 2), and the magnitude in which it retracts should decrease (Hypothesis 3) as learning trials progress. Ten terrestrial hermit crabs (Coenobita clypeatus) each received strokes to its abdomen and the number of touches required for retraction, the magnitude of the retraction, and the time it took to re-emerge from its shell after retraction was recorded. The crabs that met the 40 consecutive touch criterion for habituation were Crabs 2, 11, and 14. Out of these three crabs, Crab 11 did not show any significant behavioral changes, while Crab 2 and 14 displayed a significant increase in number of touches, supporting Hypothesis 1. For Hypothesis 2, Crab 14 had a significant decrease in latency,
You probably think horseshoe crabs are crustaceans, but you’d be wrong. They actually aren’t crabs at all, and there’s more about the horseshoe crab that you wouldn’t believe. This weird-looking marine animal survived two mass extinctions and lived in the Ordovician Period.
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).
Turtles are one of the most unique animals that roam the Earth today. They have the most unique body plans any animal has ever had. Being one of the oldest reptiles, from the order Testudines, they have gone through millions of years of adaption and evolution. Their evolution have left biologist puzzled and has demanded the attention of zoologist to study and discover the adaptation of these fascinating creatures. With the recent discoveries of Eunotosaurus africanus and Pappochelys Rosinae, biologist can finally piece together the missing links to help finally solve how turtles became the wqay they are today. The discovery of their evolution and the altercation of the Turtle and their Bauplan is astounding.
What are the differences between alligators and crocodiles? Aren’t they the same animal though, with different names? Well, actually one would be surprised by how different these two creatures actually are. Alligators and crocodiles are two of the most commonly confused animals out there. Their two families split from a common ancestor around 100 million years ago, thus forming two new families, known as the Alligatoridae and the crocodilian. This split caused them to adapt and live in different environments. The environment then played a major role in distinguishing their features and the appearance of their size, as well as their aggression levels towards humans and other animals. Learning more about these two creatures may actually open up your eyes and make you think about other objects that you see as one and may even change your attitude towards them. Alligators and crocodiles are very different in various aspects due to several factors involving their behavior and the environment surrounding them.
1. What is the difference between a. and a. Introduction Invertebrates are used in many disciplines in biomedical research, sometimes; invertebrate species are regarded as "replacement" alternatives for vertebrates (Office of Technology Assessment, 1986), presumably because they are thought to be less sentient than vertebrate species due to the fact that they have a less developed brain and nervous system. While invertebrates make up a vast number of animal species on earth, their welfare is overlooked, compared to the concern shown to higher vertebrates. In the study of pain, often ethical issues arise when testing the pain response in different animal species. The majority of research on invertebrates is concentrated on crustaceans as they are widely consumed.
Sea turtles are exquisite ocean creatures that are quickly disappearing from our oceans. The population of sea turtles in the oceans is directly affected by three main factors related to human interference. Sea turtles are one of the oldest reptile groups. They are even older than snakes or lizards. Seas turtles are quickly disappearing from our oceans as pollution from trash, oil, gases and the unconscious fisherman are hurting this beautiful creature.
