Groups of Pilot Whales Have Their Own Dialects

Groups of Pilot Whales Have Their Own Dialects

In humans, different social groups, cities, or regions often have distinct accents and dialects. Those vocal traits are not unique to us, however. A new study from the Woods Hole Oceanographic Institution (WHOI) has found that short-finned pilot whales living off the coast of Hawai’i have their own sorts of vocal dialects, a discovery that may help researchers understand the whales’ complex social structure.

Coral Larvae Use Sound to Find a Home on the Reef

Coral Larvae Use Sound to Find a Home on the Reef

Choosing a place to call home is one of the most consequential choices a coral can make. In the animal’s larval stage, it floats freely in the ocean, but once it settles down, it anchors itself permanently to the rocky substrate of a reef, and remains stuck there for the rest of its life. Exactly how these larvae choose a specific place to live, however, is largely unclear.

Sentry Completes Its 500th Dive

Sentry Completes Its 500th Dive

WHOI’s free-swimming robot Sentry completed its 500th dive on October 16, 2018, off the Pacific Coast of Costa Rica. The autonomous underwater vehicle has used its sonar systems to help scientists map the seafloor, track the Deepwater Horizon oil spill, locate the voyage data recorder on the sunken El Faro cargo ship, and carry out advanced research on many other missions to help us better understand our ocean and our planet.
