透過觀察海膽的顏色與紋路，我們發現了世界上其實存在著種類繁多的海膽，每一種都擁有獨特的紋路特徵，顛覆大家對海膽只有黑色的固有觀念。隨著研究的深入，發現到海膽並非只有單一型態，而是展現了豐富的外觀跟生態多樣性。進一步的調查也意識到，海膽在數量上過多和過少都會對環境生態系統的平衡造成了顯著的影響，導致了生態失衡的棘手問題，這使得我們不得不更加重視其在整體生態系統中扮演的角色與影響。
許多海膽物種透過啃食過剩的藻類，維護珊瑚礁的健康，並在其生存空間內促進其他生物的多樣性。在台灣澎湖過度捕撈或生態失衡，海膽數量迅速減少，進一步導致珊瑚礁退化及整體生態失衡。小琉球地區海膽數量過多時，則可能因過度取食礁岩和藻類而破壞生態平衡，形成「海膽荒礁」的現象。
綜合以上觀察與研究，海膽不僅是一種生物，更是維護海洋生態平衡的寶貴角色。看待海洋生態價值，確保其在自然環境中維持適當的平衡，並持續保護整個海洋生態系統的健康與多樣性。
Overfishing or ecological imbalance in Penghu, Taiwan, has led to a rapid decline in the number of sea urchins, further leading to coral reef degradation and overall ecological imbalance. When there is a large number of sea urchins in the Xiaoliuqiu area, the ecological balance may be destroyed due to excessive feeding on reefs and algae, forming a phenomenon of "sea urchin barren reefs". Based on the above observations and researches, sea urchins are not only a living organism, but also a valuable role in maintaining the ecological balance of the ocean. Consider the ecological value of the ocean, ensure that it maintains the right balance in the natural environment, and continue to protect the health and diversity of the entire marine ecosystem.
