Explain The External Structure Of A Frog

An aquatic vertebrate, the perch has a semi-complex digestive system. It consists of the kidneys, intestines, stomach, pyloric cecum, liver, and esophagus. When food is swallowed by the tongue, food passes through the esophagus to the stomach, which digests the food then brings it to the intestines. The liver secretes a bile to aid in the digestion process and the pyloric cecum allows fermentation to occur. Their nervous system includes a vertebral column, connected by the neural spine, the spinal cord, and finally the brain. The perch’s brain is surrounded by a skull and is located in the anterior of the body. Also, the perch has both an olfactory bulb and nerve, which relays sensory information to the brain. Finally, the perch’s circulatory system includes the two-chamber heart, a spleen, a ventral aorta (which has four branches), and its gills. Blood leaves the sinus venosus to the heart, then to the ventricle. The ventral aorta carries the blood to the gills to exchange carbon dioxide for oxygen (“Anatomy of a

Secondly, the human body, crayfish, earthworm, and frog also have many similarities and differenced of how their respiratory system works. The crayfish respiratory system is the least complex. Crayfish have gills, which are used to release carbon dioxide and to pick up oxygen, by having a constant flow of blood. Frogs consist of nostrils and larynx, which opens up two lungs. The walls of the lungs are filled with capillaries. Capillaries are

* How would you describe the structure and function of this animal’s respiratory system? Include any unique characteristics.

Overall for this change project, we have learned that the population of frogs has been decreasing all over the world. There are many factors that decrease their population like agriculture, invasive species, and the population of humans. Specifically, in California, only 40% of the historical sites in the Northwest area have Foothill Yellow-Legged Frogs, and this has the highest percentage out of all of California. These frogs are indicators for the environment, meaning they can determine if the area around them has changed dramatically due to their permeable skin. For our service project, we removed invasive plants like the Himalayan Blackberries and dug creek beds for the frogs. From this, we were able to improve the levelness of the area

Have you ever imagined a creature with transparent skin? Well, the glass frog is one of them. I know that some of you might think that they’re completely transparent like clear glass, but they’re not. The glass frog is generally transparent lime green in color like green stained glass and sometimes have transparent, clear skin on their bellies or chest so you can sometimes see their heart pumping! But not all glass frog has translucent skin! These little creatures are two centimeters to three centimeters long and many other species can grow up to eight centimeters long.

it has smooth or slimy skin, frogs tend to lay eggs in clusters. Unlike Toads, Toads have stubby bodies with short hind legs, for

They have a single closed circulatory system consisting of a heart with a sinus venosus, atrium, and ventricle. Parallel blood capillaries called rete mirabile carry blood to the gas gland and allow it to diffuse to the swim bladder.

As the frog starts to sexually mature it goes through a process called metamorphosis. The frogs body changes, it’s tail gets shorter and the frog grows four limbs Now it can swim and hop, it’s diet also charges were frogs can eat insects as well as other frog and fish depending on

In their movements, northern leopard frogs can encounter native grass prairie as well as crop fields and grazed pastures that potentially can act as barriers to their movements. Since grassland prairie and wetlands in the PPR have been greatly reduced, the wetlands that are highly depended on by the northern leopard frog to complete its’ life cycle in the prairie pothole region have become separated by greater distances. Depending on the cover type through which a frog must move, it can become exposed to the sun, wind, and other environmental factors for longer periods of time that, in turn, could cause them to lose water faster than if moving through a more naturally vegetated area. In addition, they may become more visible to predators.

BASIC INFO: This tiny frog grows to just 2.5-3cm long, weighing 2-3 grams each. They have a lifespan of 9 years, and take the first 4 preparing to breed, which they do so in a short period during the Summer months. Females typically lay between 10-40 eggs in a small nest near the edge of a pond.

The Texas horned lizard also exhibits behavioral adaptations that have increased its water-absorbing efficiency. To help increase the capture of water from its scales, the lizard lowers its head and body to the ground and sticks out its legs to increase the surface area of its body in

The Boreal Chorus Frog is a very small frog. The average size is 1-3.7 cm. The males are smaller than the females. They are brown, with some white. They have three dark stripes which can in three rows of spots. A white stripe runs along their upper lip. The toes are not webbed.

While in the Frog’s classroom, during my observations, I noticed that sharing toys among the children has been a popular conflict. During one incident, four kids were playing with magnets and Noah tried joining in but there were too many children at the table. Noah tried to grab some magnets that were already being used by another child. Noah then became angry and expressed his anger by head butting the child who was using the magnets. One of the teachers then began to notice what was going on. The teacher then told Noah that head butting was not okay and that he needs to wait his turn or go find a different toy to play with. Noah then walked away with a strong attitude. The teacher asked if he needed to take a break and sit down on his own.

The typical diet of these frogs includes beetles, mite and black ants and insect lava. During summer seasons the frog live nears these pools as it is breading season. Female frogs lay up to 20-30 eggs at a time. The eggs hatch after a few months during winter or autumn. During winter these tadpoles feed and grow until the reach warmer spring waters until they become froglets, starting their transition to become a frog. Outside the breading season adults move away from the pools into woodier habitats. These often have denser groundcover and have

Frogs, toads, caecilians, and salamanders are the members of the class Amphibian (amphi- meaning “on both sides” and bios- meaning “life”). These members always require water for reproduction. Most Amphibians undergo metamorphosis, which is a usually degenerative pathological change in the structure of a particular body tissue. And, in the case of Amphibians, it is the changing of a tadpole into
