Welcome to the Penguiness book of dive records!

The Penguiness book

This webpage is a scientific database where you will find official records of dive depth and duration for most diving species of vertebrates. This project was initiated to answer the questions regularly asked by school teachers, educators, journalists, scientists: "How deep can animals dive?". Such information is compiled here, using references from scientific articles from peer-reviewed journals, ensuring that these values are the most reliable and current estimates.
