Pages: 11 (including cover and credits). Sizes: A4 (210 × 297 mm) and US Letter (8.5 × 11 in), both PDFs included in one zip.

Printing: Print at 100% / actual size on A4 or US Letter. Inside pages use light backgrounds and print well in black and white; covers are dark, so start from page 2 to save ink.

Every fact is checked against named source pages (including Smithsonian Ocean, the Monterey Bay Aquarium, MBARI, NOAA, the Natural History Museum, the Australian Museum, the American Museum of Natural History, Shedd Aquarium, Britannica and peer-reviewed research; checked 28 Oct 2026), and the sources are listed on each pack’s credits page. Facts that can change, such as species counts, sizes and depth records, are printed with that date. Where sources give different figures, both are shown with their source.
