There are three different ways that frogs show parental care to protect their young. There are many species in which the adult frog guards over the eggs. The sex of the frog that guards the eggs all depends on the species. In some species the male watches over them and in other cases the female is the one who is doing the protecting. But in some cases it is not known whether it is the female or male because the external characteristics of both sexes are very similar. Some of these species lay their eggs over water and remain next to them, and others lay on top of them. Many of the land-dwelling frogs that will remain next to the eggs take this very seriously and will attack and animal that comes close. For the frog to leave the eggs, the eggs must be eaten by another animal or have desiccated and died. A species that continues to guards the eggs even after they hatch would be the male African bullfrog. They often have their eggs in a small pool of water so the bigger fish cannot get to them and once the eggs hatch the bullfrog will often watch over them. When the tadpoles become big enough they will dig a channel to the bigger water source so the tadpoles can swim away. Another way frog show parental care would be that the frog lays their eggs on the ground till they hatch …show more content…
When an amphibian is toxic to other animals, the amphibians skin will be bright warning colors to let other predators know that it is deadly. There a few toxins that are found in frogs skin that range in toxicity, some being extremely toxic where others are mildly toxic. Most of the toxins that are founding frogs skin affect the contraction of muscle cells. The toxins that poison dart frogs secrete is called lipophilic alkaloid, which serve has a defense against predators. Frogs do not make their own toxins but consume the toxins from their food sources such as ants, and centipedes. The toxins that are found in frogs is not meant for prey, but it is for the predator that tries to eat
There are some nice adaptations for the Strawberry dart frog. They can extract toxic alkaloids from variance of mites, ants, millipedes, and beetles. When they extract these poisons, they store it in compounds in glands on their skin. Lisa Lester says that when the frog feels threatened, they can release the toxins stored in their glands at the enemy. (Lisa Lester, “Strawberry Poison Frogs Feed Their Babies Poison Eggs”)
Sharon M. Draper’s Copper Sun had many impactful quotes that affected the characters and their ideas, most of them revolving around hope, as the message of the novel is hope is necessary for one to live and be motivated. Early on in the book, Afi was preparing Amari for the slave trading, telling Amari, “Find beauty wherever you can, child. It will keep you alive,” (Draper 64) basically telling Amari not to focus on the unpleasant parts in her experiences. The quote affects Amari many times throughout the duration of the novel, one of the first at the Derby plantation. At the plantation, Clay forced Amari to bed with him, and Amari was disgusted. As an attempt to distract herself, during their nightly encounters, Amari would think of her
In the first paragraph Dillard begins by using humor and actions to convey a sense of childlike innocence into her main character. This child has no worries and enjoys instilling “dire panic” into the frogs she finds milling about the island. Whenever the main character finds a frog still in a puddle the tone shifts to quiet and scientific. This tone shift is whenever the author stops talking about frogs in general and focuses in on one singular frog. She describes the frog as having “wide dull eyes” and “glistening skin”, then the frog begins to collapse “like
Without the horned lizard, the Saguaro desert would fall apart quickly. If you have ever heard someone say, “Hey look! There’s a horned toad!” they are really referring to a horned lizard. They have spines (spikes) to protect themselves from predators. These lizards move slowly, and are patient for their food. They eat mostly insects such as ants, and in the Saguaro desert, they eat kangaroo rats. There are 14 different species of horned lizards. They are different in some ways, but all of their colors resemble their surroundings, and it helps them to stay safer. Horned lizards can survive in many climates and temperatures. If it gets too hot, they burrow with their head sticking out at the surface of the ground. That way, it cools them down without having to go far. Conveniently they can stay in their home for the winter. They survive by burrowing in the ground and hibernating. Horned lizards mostly lay eggs, but for some species, the young are born alive. After the eggs are laid, the parents ...
When the eggs are dropped into the water, the eggs will stay whole. If we were dropping from a higher distance they would break.
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
The Permian-Triassic extinction event is undoubtedly the largest extinction event the Earth has ever seen. While evidence shows that it occurred over a great amount of time, it was effective in causing the extinction of an incredibly large portion of life on Earth. To such an extent that it took millions of years before any large amounts of biodiversity occurred again. This is why it is also referred to as the ‘Great Dying’.
First, here are some basic facts about turtles: turtles are cold-blooded, which means that they cannot raise or lower their body temperature. Their body temperature reflects the temperature of the surrounding air or water. Turtles date back to around two hundred million years ago. Having over forty nine species of turtles, they can live both in water and on land. The top shell, referred to as carapace, of land a turtle are over-grown and makes the ribs wider. Beneath the top shell is the lower shell, referred to as plastron. Both of the shells protect the turtle from other animals and their environment. Thus, turtles have developed long necks and an unusual way of getting air in and out of their lungs. A turtle’s neck forms a tight S-shaped bend, and the curve becomes shallow as the neck extends (Smith and Zim, 18). Also, having modifying their bodies, turtle legs are attached within their ribs. The unique structure of turtles has made them long-lived and unusual specie.
Poisons come in different forms and act in different ways. They can act locally, absorption through the body, or both. There are three different categories that poisons are put into: inorganic, organic, and asphyxiants...

Hello United Nations! I am going to start off by telling you a little bit about us and our organization. We are the Organization for African Endangered Animals. We are a private agency in Africa who protect the welfare of endangered animals. We are the voice of the animals. They cannot speak for themselves so we speak for them. We do our best to protect our animals but we have limited sources and funding. Our focus right now is one of the most endangered species in the world, the Dama Gazelle.
Modern-day genetic technology has granted mankind with the opportunity to bring back extinct species from the dead. If humans have come to possess the DNA from an extinct animal population, it is possible to create an identical clone of the animal in question, effectively “bringing it back from the dead”. Many ethical dilemmas surround the practice of de-extinction, and rightfully so. Recreating an extinct species could produce groundbreaking scientific breakthroughs, generating exciting opportunities for future genetics-based research. However, there could also be monumental consequences: the newly revived, once-extinct species might destroy the ecological equilibrium of modern Earth
Several mass extinctions have occurred during the Earth’s history. The Cretaceous – Tertiary Boundary (K-T) Extinction caused the loss of at least three-quarters of all species known at that time including the dinosaurs. The cause of this mass extinction is a controversial subject among scientists but the fossil evidence of it’s occurrence is abundant.
7 years), they begin their journey back to their birthing grounds to start reproducing. High water
Because the CO2 levels are rising, the ice caps are melting and many more animals can become extinct. When pangea started splitting, there was a lot of volcanic activity, which cause the death of many dinosaurs. A meteor also hit earth and the mass extinction of many land and marine animals happened. There have been five mass extinctions in Earth’s history. The worst one wiped out ninety-six percent of marine life and seventy percent of land organisms. This took millions of years to recover.
