What sound dose African elephant makes?
It is called a "trumpet" sound.
"Does" is misspelled "dose" because the inside "e" is silent, a feature normally found on words ending with an e (except that such words almost always have a "long" vowel sound, the sound of the letter, as in the rhyming words "close" and "dose"). Part of the problem may be that in typing the word, the letters "s" and "e" are close together on the keyboard.
an elephant can cost anything between £150 to £1000000, personally mine didn't cost anything as i used the law "finders keepers" and got mine as soon as it came out of it's mum. i wouldn't recommend a pet elephant as when i took mine for a walk in the woods where i live, i got lots of strange looks, and the elephant did eat a five year old.
