Took a picture, capturing animal (5)
I believe the answer is:
okapi
'animal' is the definition.
(African mammal)
'took a picture capturing' is the wordplay.
'capturing' indicates a hidden word (some letters captured or held by the clue).
'OKAPI' can be found hidden inside 'took a picture'.
(Other definitions for okapi that I've seen before include "African ruminant" , "creature" , "Shy Zairean ruminant" , "Mammal of giraffe family" , "Native of Central Africa" .)
