Re: wild dolphin seeks out human help
While both our languages divide the Order up into the two suborders Baleen Whales (Mysticeti) and Toothed Whales (Odontoceti), we Germans follow that logic and call the whole order "Whales", while you instead use an anglicized version of the scientific name (Cetacea) : Cetaceans.
We both mean the same and only use different ways to express it. (We Germans try to avoid the use of scientific names as much as possible. It's mainly a matter of spelling and keeping words short, I suspect).
Whereas we Yanks and Brits love using anglicized versions of Latin and Greek scientific names, because we think it makes us sound smarter.
