So, in this photo the far enclosure is the one for the Small-clawed Otters and the nearest one is for the Capybara. There is a passageway under the boardwalk to the dry half of the Capybara enclosure where they are fed and where their shelter is (shown in the other photo). Formerly, before the Capybara arrived, the two enclosures in this photo were both for otters and there was no boardwalk because the dry half of the Capybara enclosure did not exist then.
