Why are there so many dead sting rays on the shore during mating season?

During mating season, stingrays often congregate in shallow waters, leading to increased interactions with human activities and environmental factors. As they come closer to shore, they may become more vulnerable to stress, entanglement, or predation, resulting in higher mortality rates. Additionally, mass strandings can occur due to environmental changes or disturbances that disorient them. These factors contribute to the noticeable presence of dead stingrays on the shore during this time.
