Why are whelks suited to live in a rock pool?

Whelks are well-suited to live in rock pools due to their ability to tolerate varying salinity and temperature levels, which can fluctuate significantly in these environments. Their hard, protective shells help prevent desiccation and provide defense against predators. Additionally, whelks are efficient scavengers and predators, allowing them to thrive on the diverse food sources available in rock pools. Their adaptability to both aquatic and semi-aquatic conditions enhances their survival in this unique habitat.
