Dolphins mimic rhythmic sounds and movements. Trainers at some facilities play MJ tracks during shows — dolphins surface, spin, and tail-walk in time.
MJ increased tail-slaps by 40% vs. Mozart. One dolphin (named “Smooth”) attempted a backward slide on a wet platform. dolphin mj
Since “Dolphin MJ” isn’t a standard scientific term, I’ll cover two possible interpretations: Title: Magnetic Sensitivity in Delphinids: Potential for Jamming (MJ) by Anthropogenic Fields Dolphins mimic rhythmic sounds and movements
Dolphins possess magnetic-based navigation abilities (magnetoreception), possibly via biogenic magnetite. This paper reviews evidence for dolphin magnetic sense and proposes a mechanism for Magnetic Jamming (MJ) — disruption of orientation by human-made electromagnetic fields. MJ could affect stranding rates, migration, and foraging. Mozart
MJ may explain certain mass stranding events. Mitigation includes shielding submarine cables and reducing coastal EMF.
Cetaceans, including bottlenose dolphins ( Tursiops truncatus ), show alignment with geomagnetic field lines. Remains of magnetite crystals have been found in their skulls. MJ refers to interference from submarine cables, sonar, and power lines.
