Can you find the snakes? - A variant of X-Sums and Snakes, inspired by puzzles by Joseph Nehme, RockyRoer and Xenonetix. Note that in this version, the clued cell is not necessarily the head or tail of the snake!

Normal Sudoku rules apply.

• Cells separated by a grey dot contain digits in a 1:N ratio for some whole number N. The value of N can vary between dots.
• There are snakes hiding in the grid. A snake is a 1-cell wide set of orthogonally connected cells of length 1-9. A snake does not branch or touch itself orthogonally. Two snakes may not share cells but may touch each other. Digits along a snake may not repeat.
• A clue in the top-left corner of a cell indicates that the cell is part of a snake and gives the sum of the digits on that snake. '<6' in r6c4 means that the sum is less than 6.
• Additionally, the digit in the clued cell equals the number of cells of that snake. Note: The clued cell does not have to be the head or tail of the snake.
• The solver must find all clued snakes.
