In April 2022, mass stranding of weedy (common) seadragons occurred, with a total of over 200 individuals washed ashore on beaches in the Sydney, Australia region, recorded by citizens. Causes of the stranding, which is unprecedented, were likely related to a series of east coast low storm events, leading to record wave heights, record coastal rainfall, and potential loss of critical food sources (schooling mysid crustaceans). A significant proportion of the local population was likely lost in this series of events, indicating a future threat to seadragons, with east coast low intensity predicted to increase under human-caused climate change.
2022年4月，杂草海龙（普通海龙）发生大规模搁浅，澳大利亚悉尼地区海滩上共有200多头海龙被冲上岸，由市民记录在案。此次前所未有的搁浅事件的原因可能与一系列东海岸低压风暴事件有关，这些事件导致海浪高度创纪录、沿海降雨量创纪录，以及关键食物来源（成群的糠虾甲壳类动物）可能丧失。当地很大一部分海龙种群可能在这一系列事件中消失，这表明海龙面临未来威胁，预计在人为气候变化下东海岸低压强度会增加。
