Which direction does a frog's tongue go when extended?
959845
Well I have read that a frog's tongue actually is directed down its throat when not in use, this is becasue the base of the tongue is actually attached at the front of the mouth, this would give it a downward pointing orientation when inside the mouth, so it would only make sense that the tongue would be slightly upward when outside the mouth. You have to remember that it is not as soft and evolved as the tongue of a chameleon, the frog's tongue is somewhat more rigid.

You don't need to go all the way to the back of the tongue.  Stop just before your uvula (hangy ball in the back of your mouth).

Look at how a bug does it.\nThe side opposite the direction you wish to turn takes steps slightly longer than the side toward the turn.\nFor very quick turning, the legs take strides in opposite directions.

Tell them that in English the tongue does not touch any part of the mouth. It's a bit curled back.

Very well written. A few edits in [brackets] with explanations in (parenthesis).  English is HARD.\n\n\nAfter hatching, the tadpole will eat the [remaining] yolk (awkward) (no comma for subordinate clause) which is in their gut. [The tadpole] (pronoun-antecedent rules)  only had gills, a mouth and a tail when it first came out so it is very dangerous for them. If they [weren't] (subjunctive case for a conditional statement-tough one) careful, they [would] (matches the case) get eaten in no time[.]  (New clause) I’m so glad I’m not a frog; at least I don’t have to worry about this kind of problem! Then 7-10 days after hatching, the tadpoles can swim around[,] (separating independent clauses) and then they will not eat yolk anymore[;] (independent clause) they will find algae to eat. About 4 weeks later, the gills will start getting grown over by skin, and soon they will disappear! Wow! That really is fast! At [that] (article rules) time, tadpoles will get teeth, which can help them (no need to to leave "to chew" in the infinitive) chew and digest better. Few days after that, the tadpoles will interact and be friends with each other, isn’t that great?

east/west.\n\nto remember, longitutde has lines that are all as "long" as each other (one pole to the other.)

frogs like to swim in the water and are more aquatic than terrestrial, but they have very well developed meaty leg muscles, (both the calf and the thighs) and many muscles the same as humans which they can use for hopping too. They just use their hind legs for hopping though.  Those puny little arms-hands-muscles are not used for much other than propping themselves up when sitting, or a male may squeeze a female when he is on her back mating with her.

In general, gleeking occurs when excessive saliva accumulates in the mouth (due to stimulation of the sublingual gland) and is propelled out as a stream or mist through the narrow gap between the maxillary central incisors. This may occur accidentally (e.g. while talking, eating, or yawning) but may also be the result of deliberately forcing the saliva out via a subtle action involving strategic interplay between the tongue and lower jaw. This action is a learned skill; like ear wiggling, not everyone can do it. One popular method is to press the underside of the tongue against the palate, then push the tongue forward while pulling the lower jaw slightly backward. Another method is to yawn deeply, and then press the tongue against the palate. This method is usually more successful, but is also more obvious.

Most fishes do have a 'tongue'. Fish tongues however do not resemble the muscular tongues of humans. The tongue of a fish is formed from a fold in the floor of the mouth. The tongue of the lamprey can be protruded from the mouth. It has horny teeth and is used to rasp flesh from its prey. Most fishes however cannot protrude their tongues. \n\nThe tongue and inside walls of the mouth of the Cottonmouth Trevally, Uraspis secunda, are brilliant white. \n\nSeveral species of parasitic crustaceans (isopods of the genus Ceratothoa) are known as tongue biters. These parasites are sometimes seen on the floor of a fish's mouth 'replacing' the tongue. Current evidence suggests that the tongue is pierced at the base by the pereopods (walking legs) of the isopod, resulting in it eventually being physically detached, or atrophying and then dropping off. \n\nSome species of tongue biters feed on the host's blood and many others feed on fish mucous. Tongue biters do not eat scraps of the fish's food. Most evidence indicates that these isopods do not kill the host.

A frog may breathe by simply opening its mouth and letting air flow into the windpipe. However, it may also breathe with its mouth closed. The floor of the mouth is lowered, causing the frog's throat to "puff out." When the nostrils open, air enters the enlarged mouth. Then, with nostrils closed, the air in the mouth is forced into the lungs by contraction of the floor of the mouth.\n\nSo in order for water to enter their nose, the frog must lower the floor of the mouth (and they know how to prevent this, the same as you know that you must not breath through your nose while under water :P).

down at the center, but it is skewed toward the left. when u bring it out for peeing, u do it from the left.
