There are some new markets around for animals (9)
I believe the answer is:
marmosets
'there are some new markets around for animals' is the definition.
I can't tell whether this definition defines the answer.
'some new markets around for animals' is the wordplay.
I cannot really understand how this works, but
an anagram of 'some' is 'mose' which is within the answer.
'markets' could be 'marts' ('mart' can be a synonym of 'market') and 'marts' is found in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for marmosets that I've seen before include "Monkeys with silky coats and long tails" , "The monkeys could give Moms a rest" .)
