Mostly traipse about with Malayan mammals (6)
I believe the answer is:
tapirs
'malayan mammals' is the definition.
'tapirs' can be an answer for 'mammals' (tapir is a kind of mammal). I'm not sure about the 'malayan' bit.
'mostly traipse about' is the wordplay.
'mostly' means to remove the last letter.
'about' indicates an anagram.
'traipse' with its final letter removed is 'traips'.
'traips' with letters rearranged gives 'TAPIRS'.
'with' acts as a link.
Can you help me to learn more?
(Another definition for tapirs that I've seen is " Creatures with heavy bodies and short flexible snouts".)
