Frogs are usually small animals that have smooth, moist skin, bulging eyes, and external eardrums behind the eyes; the adults lack a tail. Frogs have long hind legs, and most species can take long leaps. Many species also have webbed feet, making them excellent swimmers.
Most frogs, especially males, are quite vocal. As the frog forces air through the voice box, or larynx, the vocal cords vibrate to make calls distinctive of its species. A much louder sound is produced by the males of species that possess vocal sacs, which swell enormously when the frog calls to attract a mate. The frog's tongue is attached at the front of the mouth instead of at the rear, and it is covered with a sticky substance, making it an efficient trap.
Like most amphibians, most frogs pass through a free-living fishlike larval stage before undergoing true metamorphosis into adult frogs. Many of these frogs lay their eggs in water, although some lay their eggs on vegetation above the water, in wet places on land, or even on the back of one of the parents. The breeding season varies according to species and geographic region but often coincides with heavy spring or summer rains. Tadpoles have gills and a tail, and most feed on algae and other vegetation, although a few are carnivorous and may even feed on their siblings. As tadpoles mature, the tail is absorbed, lungs develop, the gills disappear, legs appear, and the adult frog form is established. Some frogs, especially in the tropics, do not go through a larval phase; these frogs lay eggs, usually in damp places out of water, that hatch directly into froglets.
Behavior
Frogs live in a variety of habitats, but most prefer moist regions. Although they are air breathers, frogs can stay underwater for long periods, and they can breathe through the skin. Tree frogs are adapted for tree living; other frogs are permanently aquatic; still others spend most of their lives in underground burrows, coming up only to feed or breed.
In reproduction, the female produces clusters of eggs that she carries in one or two egg sacs that are attached to her abdomen. Once hatched, The T. Californium’ life cycle has quite a few stages. The first being six naupliar (young) stages lasting 4 – 10 days. Next come the 6-copepodite stages (7-14 days for the first 5 stages) ending in the last stage where T.californicus is a sexually mature adult. Adults then live from 40 – 90 days after the stages are complete (Rickets and Calvin 1985).
The frog’s back is usually textured with coarse tubercles. Its fingers are thinly webbed while the hind foot is more developed. Large disks exist on the fingers and toes to assist with climbing and sticking to objects (Dickerson, 1969). The male and female Grey Tree Frogs are very similar. They are distinguished by the male having a dark underside of his throat. Also the females ears are smaller then the males (Dickerson, 1969).
There are at least 145 living species of the suborder Anthropoidea . Over 90% of them are monkeys. The remaining species are apes and humans. The anthropoids (members of the suborder Anthropoidea) have been the most successful primates in populating the earth. They are generally larger, more intelligent, and have more highly developed eyes than the prosimians.
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
Samuel Longhorn Clemens, or better known as Mark Twain is recognized for his novels set in his adolescence (America 's Story from America 's Library). Mark Twain was born on November 30, 1835 in Florida, Missouri and was the sixth of seven children. At the age of four, Mark Twain moved to a small frontier town in Hannibal, Missouri, on the banks of the Mississippi River with his family. Years later, on April 21, 1910 Mark Twain died in Redding, Connecticut in his sleep. Mark Twain’s purpose for writing his novel The Adventures of Huckleberry Finn was to provide a clear view of the culture and lifestyle during the period of the novel.
And, as many of mentioned in Peter Salwen’s article that, “(Twain’s) writing is offensive to black readers, perpetuates cheap slave-era stereotypes, and deserves...
Although the relationship was stable regarding gender, income, education level and different scores on the Cognitive dimension, consumer with high and low scores on the Emotion dimension will have significantly different Brand Related Rewards scores. Although the partially constrained model did not confirmed a moderation effect of Emotion on the BehaviorBRR relationship metric invariance was confirmed. Since an Emotion-Cognitive and Emotion-Behavior interplay are predicted by theorists (Clore et al., 1987), this empirical result is a support to such
First, Hester is one guideline that with reveal sin and also leads to many different sins. She suffered from the strange insight and had been isolated from Puritan society, however, she only suffered from outside not from inside. Different from Hester, Arthur Dimmesdale is totally opposite. He is a noble man in front of people, but behind his majestic mask, he is an ugly sinner and always without forgiveness. He suffered not from outside. He was afraid his mask would be disclosed and expose his true colors, therefore, he refused to confess his sin which leads to his wife’s suffering, his daughter’s acceptance, and his own tribulation. Hawthorne used his detailed language with romantic writing style to describe the struggle of two lovers. The red color letter “a”, as the second main guideline, is the most typical symbol. The letter, with an unlimited imaginary association, made people wandering in Hawthorne’s fiction world. Red is the color of blood and fire, also a symbol of life, strength, and passion. Fire is the source of light and heat of human life, and the fire of love is the source of human life. Hawthorne combines symbolism with romanticism and endows this letter a new life. Hawthorne also focuses on the consequence of selfishness, guilt, and sin in this book. He uses his meticulous technique to describe a
When I had asked her about telling me what she does on a daily basis, we had to stop sometimes for her to have a break, (bathroom, drink and a snack). I did not do a pre-interview knowing I already know my grandma. We had done the interview in a nice quiet place, free from distractions and fairly early in the morning. I did mention to her...
Twain’s famous novel, The Adventures of Huckleberry Finn, plays on the mentality and social structure of his time and its people. He saw the critical weaknesses in our values and ideals as a society during his life. He wanted to express his satirical views to the public and bring light to our society’s problems. Twain had successfully accomplished his task when he published the controversial book that is still argued today. Huckleberry Finn shows how major themes like education, religion, and morality, can be seen in his view.
Romanticism and Puritanism collide in Nathaniel Hawthorne 's The Scarlet Letter, as Hawthorne’s characters are dealt with a conflict between following one’s own moral code versus following the code of a pious and conservative society. Hawthorne introduces characters who are in a struggle to rebel against a stubborn society. Throughout his novel, Hawthorne allegorizes a Romantic moral that expressing one’s true beliefs and emotions is ultimately rewarding. Across their progression, the characters Hester Prynne, Arthur Dimmesdale, and Roger Chillingworth embody such Romantic moral.
Otters are the smallest out of all the marine animals. Female otters are generally smaller than male otters. Their tail is about one-third of their body and is used to help them dive deeper. To swim, otters use their hind flippers and tail. An otter’s body is very slender and long. They are extremely flexible, so they can groom all of their body. Their eyes are small and their ears are just visible. All otters have a very good sense of smell and can hear very well. Their whiskers can sense vibrations in the water which comes in handy when they are hunting. Most types of otters have retractable claws which allow them to better grip their food. “It is the only marine animal capable of lifting and turning over rocks, which it often does with its front paws when searching for prey” (“Otter Anatomy &
The common hippo has toes that can easily move around in water and on land! Each of their feet has four hoofed toes that have webbed feet. Those webbed feet between each toe can use for simple movements in the water. With this animal it can be able to move around and ease through land and water. Adult hippos can hold their breath underwater up to 6 minutes. They also have a large head but very short legs. They have small ears but very huge teeth. Did you know that the nostrils that they use for breathing are located at the top of the head? Wow who knew that?
