Frogs

No, the Rana temporaria frog, also known as the common frog, is not considered poisonous to humans. However, some frogs have toxins on their skin for protection against predators, so it is always best to avoid handling wild frogs.

The inside of a frog's stomach has hard ridges. These hard ridges help mix the food with the digestive fluids when the stomach muscles churn the contents. The shape of these hard ridges is actually the shape of frog's stomach.

In frogs and all other vertebrates lining of stomach and small intestine is made up of mucosa . But mucosa of small intestine possess villi which are finger like projections which increase surface are for absorption .Villi are absent in stomach .

Chickens will lay eggs year round. Laying usually dies of in the winter and with the age of the chicken. The reason they lay less in the winter is do to the cold and shorter days (this is why commercial farms keep them in constant light). As for time of day every chicken is different.

Mink frogs typically eat a variety of insects, including beetles, ants, spiders, and flies. They may also consume small invertebrates like earthworms and snails. Mink frogs are opportunistic feeders and will consume prey that is readily available in their environment.

Tadpoles need to eat a lot to turn into frogs. If allowed to become too hungry, they can eat other tadpoles. Other than eating each other, they prefer a diet consisting of plants.

Coquí is the common name for several species of small frogs endemic to the archipelago of Puerto Rico and the Virgin Islands, onomatopoeically named for the loud sound (sometimes reaching as high as 100 dB)[citation needed] the males make at night

The peritoneum in a frog serves as a membrane that lines the abdominal cavity and provides support and protection for the internal organs. It also helps to hold the organs in place and allows for some degree of movement during digestion and respiration. Additionally, the peritoneum plays a role in the immune response by producing fluid that helps to fight infection and inflammation.

Frogs will eat any live animal they can stuff in their mouths, so yes, they are predators.

African dwarf frogs are native to central Africa, specifically found in shallow waters such as streams, ponds, and swamps. They prefer warm, stagnant or slow-moving waters with plenty of vegetation for hiding and laying eggs. These frogs are commonly kept as pets in aquariums due to their small size and peaceful nature.

They are obmivores
they prefer dried blood worms. but if you go to http://www.wildcreatioms.com/ you can buy food pellets that taste like blood worms that your African dwarf frog(s) will enjoy
From my personal experience, they DO NOT eat fish flakes. They only eat live or frozen food or certain pellet food. I myself use 'JMC HIGH PROTEIN FISH FOOD' which they seem to like a lot.

Adult frogs usually breathe through their skin and lungs. They absorb oxygen through their moist skin, which is rich in blood vessels, when on land. When in water, frogs rely more on their lungs for respiration, taking in oxygen from the water through specialized sac-like structures.

The ureters, in both males and females, transports the urine from the kidneys to the bladder where it is stored until it is convenient to release through the urethra. This release is called micturition, or more commonly, urination.

The frog's tongue is attatched near the front of the mouth rather than the rear. This means that it can be curled at the base of the mouth with the tip pointing backwards towards the frog's throat. The tongue can therefore be flipped out very quickly in order to catch insects and other prey. Mucus glands in the frog's mouth also produce a sticky substance which makes it easier for prey to stick to the tongue.

Pancreatic juice in a frog travels from the pancreas through a duct that empties into the duodenum of the small intestine. When the frog eats, the presence of food in the duodenum triggers the release of pancreatic juice to aid in digestion.

A number of frogs may do something at the same or at nearly the same time, but they are not acting as a "pack" because they don't work like that. A dozen frogs may be hanging around together in a group of lily pads, but it's "each frog for himself" if food comes along or if a predator appears. They are there by individual choice and not to "create a pack" for some reason.

The pylorus in frogs functions as the muscular valve that regulates the passage of food from the stomach into the small intestine. It helps control the flow of partially digested food and stomach acid from the stomach to the intestines for further digestion and absorption.

Frogs love lily pads because they offer strength and security. They give the frog a safe place to go to catch food or a place to bask in the sun.

The digestive system of a frog consists of the mouth, esophagus, stomach, small intestine, large intestine, and cloaca. Food is ingested through the mouth, passes through the esophagus into the stomach for digestion, then moves to the small intestine for absorption of nutrients, and finally to the large intestine for water absorption before waste is excreted through the cloaca.

In frogs, the respiratory system involves the exchange of gases through their moist skin and lungs. The circulatory system works to transport oxygen absorbed by the respiratory system to various tissues in the body and remove carbon dioxide. The two systems work together by ensuring that oxygen is delivered to the cells and carbon dioxide is removed efficiently.

The blood passing into the frogâ??s aortic arches is a mixture of both the deoxygenated blood from the right atrium and the oxygenated blood from the left atrium. This mixture contains enough oxygen to supply the needs of the rest of the body.

They eat anything from algae to dead polliwogs. You can put in things like algae tablets but that is pretty much optional. To recap you really don't need to put anything in it until they are frogs. Hoped this helped!
