Could you have a whelk for a pet?

Yes, you can have a whelk as a pet, though they are not common choices. Whelks are marine snails and require specific care, including a suitable aquarium environment with saltwater and appropriate tank mates. They can be interesting to observe, but potential owners should research their habitat needs and diet to ensure a healthy life. Overall, they are more suited for experienced aquarists rather than casual pet owners.
