Family take a dip, busy creatures (11)

I believe the answer is:

descendants

I'm a little stuck... Click here to teach me more about this clue!

'family' is the definition.
(thesaurus)

'a dip busy creatures' is the wordplay.
'a dip' becomes 'descend' (I am not sure about this - if you are sure you should believe this answer much more).
'busy creatures' becomes 'ants' (I've seen this in another clue).
'descend'+'ants'='DESCENDANTS'

'take' is the link.

Can you help me to learn more?

(Another definition for descendants that I've seen is " Grandkids, e.g.".)

I've seen this clue in The Telegraph.
