This paper analyzes sperm whale foraging behavior using acoustic and movement data to show two distinct prey-capture tactics within persistent search patterns.

This paper shows sperm whale codas resemble human vowels in acoustic properties and pattern similarly across multiple dimensions, suggesting a close parallel to human phonology.

This study identifies structured formant patterns in orca vocalizations, showing convergent spectral structures with human speech and sperm whale calls.

The paper identifies and characterizes velamins, a new class of Ca2+-regulated photoproteins from Velamen parallelum that emit green light, with potential applications in analytical systems.
