Frogs

The nostril openings towards the tip of its snout that it breathes through (its nose).

There are internal nares that close off when the frog is underwater.

It depends on the species, most frogs are born out of an egg, and metamorfose in the water. Some are born alive (eg Nectophrynoides), others are carried by their parents and are born out of a pouch on the back, or in the mouth of the adult frogs. Some extinct frogs are known to carry their young in their stomach (eg Rheobatrachus).

frogs travel out onto the pavement at this time because moist nights make for good amphibian travel weather. “They breathe through their skin so they are susceptible to drying out when the sun is out. When it's rainy they can go wherever they want and not worry about it.

Frogs usually lay eggs in any pools or large puddles they can find, especially after a heavy rain. Eggs take between 6-21 days to hatch. Firstly they are tadpoles and then through metamorphosis, they become adult frogs.

Pollution and habitat loss are two factors that could reduce the frog population.

Don't know what you mean by 'serious.' Do you mean 'serous' as in fluid-filled?

The membrane that can cover over a frog/toad's eyes (and other amphibian, reptile, even mammal species) is known as a 'nictating' membrane. It is there to protect against fluid and debris from coming into contact with the corneal surface of those eyes.

yes, tadpoles will eat other dead tadpoles if not fed, and sometimes if they are not fed they will nip at each others tails.

hope i helped!

The Japanese people themselves don't eat dogs. In Japan, the consumption of dog meat is taboo, and dog slaughter is illegal.

The eating of dog meat, in itself, is legal in Japan. Japan annually imports dog meat from China to be served in restaurants. It's not common place or widespread, but it's legal and is eaten. It is usually found in Chinese restaurants, and not in traditional Japanese restaurants.

tree frogs do It depends what type of forest you mean. If you mean Rain Forest, yes. There are poisonous ones there and tree frogs also. Even in a regular forest there are bull frogs, regular frogs and toads. Hope this helps.

vertebrate means with a backbone so frogs are vertebrates and amphibians

First. Their hind legs make up a large mass of total muscle in their bodies. Second. Their muscles in their rear legs use the all or nothing response when it comes to making a jump. They do not use this response for ambulation in normal walking or swimming.

Yes, frogs and toads can respire through their skin as well as through their breathing apparatus and lungs. This is very important for those living in areas where temperatures fall below freezing. This enables frogs to hibernate at the bottom of ponds and continue breathing through their skin.

The world's smallest frog is a tiny species discovered in New Guinea, known as paedophryne amauensis. Discovered in 2010, it was only described in January 2012. Not only is it the world's smallest frog; it is also the world's smallest known vertebrate, to date. This little frog is about the size of a house fly - just 7 mm long. the tree frog.

The dog can start to foam at the mouth and the frog have a lot of chemicals on its' skin.

yes, it goes from a tadpole in the water to a frog on land (all amphibians go through some type of change)

The immature form of an animal such as a tadpole is called larva.

You will need:

plastic apron, latex gloves, goggles, dissecting tray, paper towels, scalpel, dissecting scissors, dissection probe, forceps, dissecting pins, and a plastic bag to place the remains in before discarding in the trash. You might go on-line and find a set of directions also.

Amphibian larvae use gills to obtain oxygen from the water they live in, then during metamorphosis, most amphibians lose their gills, and grow lungs.

Glass Frogs eat its own babies sometimes. They also eat small insects and leaves.

yes!

In most cases, yes, but much of how much food an animal of any size needs to live is determined by the nutrients in the food they consume the most. Though this is not true 100% of the time, many herbivores, for instance, tend to consume more because the food they eat is not overly nutrient rich.

This is because the frog skin secretes a mucus that helps keep it moist

Frogs have webbed feet to help them swim efficiently and navigate through water. The webbing between their toes increases surface area, allowing them to push more water and propel themselves forward with greater ease. This adaptation is essential for frogs that spend a significant amount of time in aquatic environments.
