The smallest dolphin is the New Zealand Tonin, also known as Hector's dolphin.
This endemic species lives in New Zealand around the South Island and west of the North Island. The largest individual measured so far was 150 cm long and weighed 57 kg.
The risk of death from the bite of these spiders is low, especially outside South America.
Phoneutria boliviensis is the most commonly detected Brazilian cottonmouth in transport, and no deaths from bites by this species have been documented to date.
