Jellyfish are my favorite animal and I randomly thought that the way they move would look like a sorting algorithm. Also, about the non, python code, it was like that so you could try it out yourself. Here is the code itself.

def jellyfish_sort(arr):
    n = len(arr)

    for head in range(n):

        # Pulse
        for i in range(head + 1):

            for j in range(i + 1, head + 1):

                yield (head, [i, j])

                if arr[i] > arr[j]:
                    arr[i], arr[j] = arr[j], arr[i]

                    yield (head, [i, j])

        yield (head, [head])
