## 题目原文

00:00:00,099 
 Part four: The Seahorse. 
 00:00:04,079 
 The seahorse might have developed as a result of movements in the Earth's crust. 
 00:00:09,479 
 These geological changes led to the formation of new habitats. These environments included stretches of shallow water and different types of vegetation, such as a specific kind of grass. 
 00:00:23,260 
 Seahorses have several unique characteristics. They swim in an upright position and have skin that stretches over bony plates. 
 00:00:31,619 
 A distinctive crown sits on top of their head. For movement, they rely on their dorsal and pectoral fins. They use their snout to catch food, and their favorite prey is shrimp. 
 00:00:45,659 
 In seahorse reproduction, the female places her eggs into the male's pouch. 
 00:00:51,399 
 Once they hatch, the young remain in the pouch for a period. 
 00:00:55,919 
 During this time, the salt level is regulated to help them adjust to life in the ocean. 
 00:01:02,359 
 Newborn seahorses face several challenges to survival. They can be eaten by predators or swept away by ocean currents. 
 00:01:11,739 
 Among human-related dangers, fishing poses the greatest threat. In captivity, many seahorses struggle due to stress, which has been a major cause of low survival rates. However, captive breeding programs have helped lower the risk of disease.
