What was the cause of death revealed in a recent necropsy of an endangered Indian Ocean humpback dolphin that washed ashore on Kozhikode beach?
The necropsy revealed fatal plastic fishing net ingestion, highlighting the growing threats of marine pollution and 'ghost nets' to India's marine life.
Consider the following statements regarding Marine Mammal Strandings in India: 1. The number of marine mammal strandings in India is decreasing. 2. Coastal dolphins are among the species most vulnerable to marine pollution. 3. CMFRI data show that 50% of stranded marine mammals are dead before washing ashore. How many of the above statements are correct?
The statement about decreasing strandings contradicts CMFRI data showing high marine mammal strandings. Coastal dolphins being vulnerable is supported by the source. The 50% mortality rate claim is not supported as there is no specific data mentioned in the text.
Consider the following two statements: Statement-I: Marine pollution is a growing threat to Indian Ocean humpback dolphins. Statement-II: The ingestion of plastic fishing nets by these dolphins is a major cause of their death due to marine pollution. Which one of the following is correct in respect of the above statements?
Statement-I is supported by the fact that the necropsy of an Indian Ocean humpback dolphin revealed fatal plastic fishing net ingestion. Statement-II provides a causal explanation for why marine pollution is a growing threat to these dolphins, as it highlights one of the specific ways in which they are being harmed.
