Similarly, endangered dolphins like the Maui’s dolphin are on the brink of extinction due to entanglement in fishing gear. The Maui’s, a sub-species of Hector’s dolphin found in the waters of New Zealand, are teetering on the brink, with current estimates suggesting fewer than 100 members remaining in existence.
