Do I need ETH to send USDC?

I've been exploring the world of cryptocurrency, and I'm particularly interested in using stablecoins like USDC. However, I'm a bit confused about the process of sending USDC. Do I need to own Ethereum (ETH) in order to send USDC? I've heard that USDC is an ERC-20 token, which suggests some kind of association with Ethereum, but I'm not entirely sure how it works. Could you clarify this for me? Is ETH a prerequisite for sending USDC, or is there another way to do it? I'd appreciate any information you can provide to help me understand this better.
