These slow lorises are not officially on show - not labelled and with no viewing other than these little portholes behind the Owston's Palm Civet exhibit.
They were imported from Asia - most are good old [i]Nycticebus coucang[/i] but the second one along (shown here) is very much darker and with a different texture of fur - I understand it is believed to be a Bengal Slow Loris, [i]Nycticebus bengalensis[/i]. A lifetime first for me, if so.
