How to write 'seaweed'?


This video (<https://www.youtube.com/watch?v=L8fVS78tvzU>) says that seaweed
is written like 海草、but Google Translate later told me it's instead 海藻, with 藻
as the second Kanji instead of 草. I know GT shouldn't be trusted, but I Google
Image searched 海藻 and got pictures of seaweed, so.. can someone tell me which
really means seaweed?




If you mean edible seaweed, 海藻 is right to use. Nori, wakame, mozuku, hiziki
and mekabu are all 海藻. They look like <http://bit.ly/1gfJick>

In Japan, usually, people don't eat 海草. Dugongs like to eat 海草.

海草 is often used to mean 海藻 by mistake.
