As apex predators, orcas can prey on whichever marine animal they choose—large or small. During a recent expedition off the coast of the Kamchatka Peninsula, scientists captured rare footage of orcas attacking a 40-foot-long minke whale.
Earlier today, four ships from Japan’s Institute of Cetacean Research returned to their home port after a “scientific” expedition to the Antarctic region. The fleet claims to have captured 333 minke whales—including pregnant females—in blatant disregard of an international ruling.
The "bio-duck" noise is a mysterious sound that submarine operators and scientists have been hearing in Antarctic waters since the 1960s. Nobody was sure what generated the repeated, quack-like pulsing sound — until now.
The anti-whaling group Sea Shepherd has released a disturbing video showing four dead minke whales aboard a Japanese whaling vessel located in protected waters. Conservationists are outraged at the Australian government which doesn't appear to be doing anything about it.
All whales and dolphins are descended from terrestrial mammals, ancient creatures that were very similar to the modern hippopotamus. Now, a fascinating new genetics study shows the incredible evolutionary changes these animals had to experience to become the perfectly adapted marine animals we see today.
