This is a math problem that can be solved by setting up an equation. According to the first search result¹, the answer is **64 jellyfish** in total. Here is the explanation:
Let's call the number of jellyfish Spongebob has **3x** and the number of jellyfish Patrick has **5x**. We know that Spongebob receives 16 less jellyfish than Patrick, so we can set up the equation **5x - 16 = 3x**. Solving for x, we get **x = 8**.
Now that we know x, we can find the total number of jellyfish by adding up Spongebob's and Patrick's jellyfish. Spongebob has **3x = 3 (8) = 24 jellyfish**. Patrick has **5x = 5 (8) = 40 jellyfish**. The total number of jellyfish is **24 + 40 = 64**.
So there are **64 jellyfish** in total.
