Factcheck Notes

1. Reported estimates of same-sex pairings and divorce rates in penguins vary across species and populations. Some studies have found values similar to those mentioned here, although these should not be treated as general estimates.

2. Rostrum-to-genital interactions in dolphins have been interpreted in multiple ways. In addition to possible sexual functions, studies suggest they may facilitate the inspection of chemical cues, allowing dolphins to gather information such as identity or reproductive status. Therefore, describing this behavior solely as a form of oral sex may oversimplify its potential functions.

3. Although it has been suggested that dolphins may obtain information by listening to the echoes produced by another dolphin’s echolocation, there is currently insufficient evidence that dolphins can intentionally transmit complex 3D images or engage in "holographic communication". This remains mostly a speculative hypothesis rather than an established scientific theory.
