Study involved whales off Californias coast •  The responses are complex and depend on a number of interacting factors Some blue whales off the coast of California change their behavior when exposed to the sort of underwater sounds used during U.S. military exercises, according to a study funded by the U.S. Navy Chief of Naval Operations Environmental Readiness Division and the U.S. Office of Naval Research.

At this point, some old conservative guys should step in and tell us that this isn't really happening, and top it off with a couple of empty platitudes about liberty.

NO but I would point out, that fish finders and cruise sonar navigation systems, also play some role in this.

Sperm whales (Physeter macrocephalus) are highly social mammals that communicate using sequences of clicks called codas. While a subset of codas have been shown to encode information about caller identity, almost everything else about the sperm whale communication system, including its structure and information-carrying capacity, remains unknown. We show that codas exhibit contextual and combinatorial structure. First, we report previously undescribed features of codas that are sensitive to the conversational context in which they occur, and systematically controlled and imitated across whales. We call these rubato and ornamentation. Second, we show that codas form a combinatorial coding system in which rubato and ornamentation combine with two context-independent features we call rhythm and tempo to produce a large inventory of distinguishable codas. Sperm whale vocalisations are more expressive and structured than previously believed, and built from a repertoire comprising nearly an order of magnitude more distinguishable codas. These results show context-sensitive and combinatorial vocalisation can appear in organisms with divergent evolutionary lineage and vocal apparatus.


Seems to say that whales have a language.
