![]() The construction of dams, pollution from industrial activities and shipping, and the degradation of the river’s water quality resulted in the degradation and fragmentation of the dolphin’s natural habitat. Habitat degradation also played a role in the decline of the Baiji Dolphin. The Baiji Dolphins’ low reproductive rate and small population size further exacerbated their vulnerability to such incidental capture. These fishing nets posed a significant threat to the species, as they were not selective and had a devastating impact on the dolphin population. The primary factor contributing to the decline of the Baiji Dolphin was the use of fishing nets with hooks, which inadvertently caught and drowned the dolphins as bycatch. Its coloration ranged from light gray to bluish-gray, and it had a prominent white belly, giving rise to its alternative name, the white fin dolphin. It possessed a unique and graceful appearance, with a long and slender body, a distinctively long snout, and a characteristic curved dorsal fin. The Baiji Dolphin was once native to the Yangtze River in China. Its disappearance was officially recognized in 2020. Tragically, it is believed to be the first dolphin species to have been driven to extinction directly due to human activities. The Baiji Dolphin, also known as the Chinese river dolphin, Yangtze river dolphin, Yangtze dolphin, and white fin dolphin, was a possibly extinct species of freshwater dolphin. However, these measures proved insufficient to counteract the rapid pace of habitat destruction and the associated impacts on the frog’s population. The loss of connectivity between fragmented habitats further limited the frog’s ability to disperse and find suitable areas for survival.Įfforts were made to conserve and protect the Splendid poison frog, including establishing protected areas and implementing conservation programs. It became increasingly vulnerable to predation, disease, and the disruption of its reproductive cycles. As the forests were cleared, the frog lost its shelter, breeding grounds, and food sources. The destruction of the Splendid poison frog’s habitat had severe consequences for the species. Additionally, the growth of urban and suburban areas, along with the construction and use of rail lines, further fragmented and destroyed the remaining forested areas. The expansion of human activities, such as logging and the conversion of forests into agricultural land, resulted in the loss of the frog’s natural habitat. The primary factor contributing to its demise was deforestation and habitat degradation. Unfortunately, the Splendid poison frog faced numerous threats that ultimately led to its extinction. These toxins, derived from the frog’s diet of ants, beetles, and mites, made it one of the most poisonous amphibians in the world. This combination of colors served as a warning to potential predators, as it signaled the presence of potent toxins in the frog’s skin. It possessed a brilliant array of colors, with a predominantly blue body and contrasting black markings. One of the most distinctive features of the Splendid poison frog was its striking coloration. This frog inhabited the humid lowland and montane forests of the region, adding a vibrant touch to the diverse ecosystems it called home. It was endemic to the eastern end of Cordillera de Talamanca, located in western Panama. The Splendid poison frog, also known as the splendid poison-arrow frog (scientific name: Dendrobates speciosus), was a strikingly beautiful species of poison dart frog that was sadly declared extinct in 2020.
