Here I have created both non-tiled and tiled DynamicMapLayer version for comparison  using plain esri-leaflet and esri-leaflet with plugin.

" Freshwater Ecoregions of the World, (FEOW)  provides a new global bio-geographic regionalization of the Earth's freshwater biodiversity.  Covering virtually all freshwater habitats on Earth, this first-ever ecoregion map, together with associated species data, is a useful tool for underpinning global and regional conservation planning efforts, particularly to identify outstanding and imperiled freshwater systems; for serving as a logical framework for large-scale conservation strategies; and for providing a global-scale knowledge base for increasing freshwater biogeographic literacy. " "Over a decade of work and contributions by more than 200 leading conservation scientists have produced a first-ever comprehensive map and database of the diversity of life in the world’s freshwater ecosystems. The map and associated fish data – a collaborative project between World Wildlife Fund and The Nature Conservancy."   For the fish lovers, the map i...
