spatial dynamics, based on just 31 animals

I've never before heard of spatial dynamics, but "dynamics" is about how things move and "spatial" is about space, so I would guess that sharks' spatial dynamics means the way a group of sharks move together - e.g. when they travel or hunt prey, do they tend to take up the same formation every time? how much "personal space" does each shark take up? do members of the group make way for dominant members? Stuff like that.

And based on just 31 animals means that this study is based on observation of a group of only 31 animals.

And based on just 31 animals means that this study is based on observation of a group of only 31 animals.

You mean 31 sharks? Please make it clear and accurate. For a foreigner may think it to be 31 makerels, simons, etc.

This may be the largest-ever study of great white sharks' spatial dynamics, but it's still based on just 31 animals.


They studied thirty-one white sharks to discover the details of how they use the space around them.

Yes, 31 sharks. How could a research project on sharks' spatial dynamics possibly be based on a study of 31 mackerel or salmon?

Easy there, syntinen, he's learning English and we are learning a bit about making thing clearer.

Yes. Hehe. Thank you. And thank you Joe for explain that for me.

One thing to watch for for, especially with American writers, is the use of synonyms. They try not to use the same word for something more than once in the same sentence, hence the "study of sharks" based on "thirty one animals" instead of sharks and sharks.

Thank you. And that make it more difficult for a foreign writer for we must use different words when we express something. Hehe.
