Whale food chain. They have large reserves of blubber, more so for toothed whales as they are higher up the food chain than baleen whales. Lactating mothers can pass the toxins on to their young. These pollutants can cause gastrointestinal cancers and greater vulnerability to infectious diseases. They can also be poisoned by swallowing litter, such as plastic bags. Advanced military sonar harms whales. Sonar interferes with the basic biological functions of whales—such as feeding and mating—by impacting their ability to echolocate. Whales swim in response to sonar and sometimes experience decompression sickness due to rapid changes in depth. Mass strandings
Toothed leaf chameleon Toothed leaf chameleon The toothed leaf chameleon, Brookesia dentata, is a species of chameleons endemic to northwestern Madagascar. It was first described by Mocquard in 1900: 345, and has been described numerous times since then, most recently by Townsend "et al." in 2009. It is affected by the collection of charcoal, forest fires, and the grazing of cattle. The toothed leaf chameleon is endemic to northwestern Madagascar, and its type locality is Sberbieville. It has been confirmed to be found at Andasibe, Mandraka, and Angavo-Anjozorobe. At the highest, the species can be found at above sea level. The International Union
