Threats to Orcas
Recent studies have found that orcas are amongst the most contaminated marine mammals in the world. Pollution and chemical contamination make orcas more susceptible to disease and likely cause reproductive difficulties.
Size: Male orcas can grow up to 23 feet long, while females top out around 21 feet.
Weight: Males weigh seven to ten tons, and females weigh 4 to 6.
Lifespan: Orcas live 30 to 50 years in the wild.
