Author/Opus: This is the 177th puzzle from our contributing puzzlemaster Murat Can Tonta.
Rules: Blacken some cells and then locate two snakes (1-cell wide paths). The snakes do not touch themselves or each other, not even diagonally. All remaining white cells must be part of the snakes with the heads and tails given in the grid. Outside clues indicate the size of all groups of blackened cells in that row or column in order. There must be at least one white cell between each of these groups. When no clues are given, any number of cells may be shaded in that row/column.
