Our Kid - Scouse Rhino

The one that got away. Tracked this rhino down at Liverpool Lime St station. Got me wondering how he got there. Did he swim across the Mersey or just go through the tunnel like the rest of us?o
Which got me thinking. Can rhinos swim? The answers I have found on the web vary from yes, no and not very fast about 3 miles an hour. Can someone please answer this question once and for all?
