ZF_2_05 — Whale Biology and Cetacean Communication

Cetaceans — the order comprising whales, dolphins, and porpoises (~90 living species) — are among the most cognitively sophisticated and communicatively complex animals on Earth. Evolved from terrestrial artiodactyls tha

ZB_1_15 — Infrasound Communication in Wildlife

Infrasound (frequencies below 20 Hz) and low-frequency communication (<100 Hz) are used by elephants, whales, okapi, cassowaries, alligators, and other species for long-range signaling across distances exceeding 10 km. K

ZB_1_18 — Infrasound Communication in Animals: Elephants, Whales & Seismic Signaling

Infrasound — acoustic frequencies below the typical lower limit of human hearing (~20 Hz) — serves as a long-range communication channel for some of Earth's largest animals, enabling coordination over distances of kilome

R_4_08 — Echolocation and the Evolution of Sensory Systems

The evolution of sensory systems represents some of the most striking convergent solutions to ecological challenges across the animal kingdom. Echolocation — the ability to emit sound pulses and interpret returning echoe
