Sperm Whales Adopt Malformed Dolphin Into Their Group

Herman Melville’s Moby Dick may paint a picture of the sperm whale as a terrifying, ferocious creature that destroys ships and attacks the sailors on them, but modern research shows that sperm whales are compassionate and social creatures, dangerous only to the fish and squid that the giant whale feasts on for dinner, or to the orca whales that prey on sperm whale calves. A heartwarming and unusual recent discovery does even more to distinguish the sperm whale from its deadly reputation, as a group of sperm whales were observed “adopting” a bottlenose dolphin with a spinal malformation.


Behavioral ecologists Alexander Wilson and Jens Krause discovered this unique phenomenon when they set out to observe sperm whales off the island of Pico in the Azores in 2011. Upon arriving there, they discovered a whale group of adult sperm whales, several whale calves, and an adult male bottlenose dolphin. Over the next eight days, the pair observed the dolphin with the whales six more times, socializing and even nuzzling and rubbing members of the group. At times, the sperm whales seemed merely to tolerate the dolphin’s affection, while at others, they reciprocated. "It really looked like they had accepted the dolphin for whatever reason," Wilson reports to ScienceNOW. "They were being very sociable."

Tiny Fish Climb Giant Waterfalls for Love

If you think the dating world is tough for a human, consider for a moment the Nopoli rock-climbing goby of Hawaii, which scales waterfalls up to 100 feet high in order to breed. To put this feat in perspective, it’s the equivalent of a man of average height scaling the 29,029 feet of Mount Everest!


The process leading to this incredible feat is, quite literally, jaw-dropping: the tiny one-inch goby propels itself up the waterfall rocks with two suckers – one, common to all gobies, on the belly, and a second, particular to one goby genus, that develops when the mouth migrates from the tip of its head to its chin over the course of 36 to 48 hours, before it embarks on its journey. The fish uses these dual suckers alternately to inch up the rocky substrate of waterfalls to the waters above where the goby mates and deposits eggs in streams. Upon hatching, these juvenile gobies are swept into the ocean where they develop for several months before they return to freshwater streams and pools upstream where they may live for several years. To mate, the gobies of this new generation must repeat the waterfall-climbing process themselves.

As 2013 rapidly approaches, we wanted to take a moment to reflect on the past year at Oceana. Thanks to your support, we were able to achieve more than a dozen major victories for the oceans! You signed petitions to lawmakers and companies, submitted seafood samples and participated in rallies and events, and it made a difference. Here are five of the major victories we won in 2012 as a result: 

1. Alibaba.com stops selling manta ray products

When Oceana discovered that the online international marketplace Alibaba.com was selling manta ray products, we asked for your help in stopping it. Nearly 40,000 of you responded by signing our petition, and Alibaba listened, removing manta ray leather products from the website.

2. Victories for the endangered Pacific leatherback sea turtle

2012 was a good year for endangered Pacific leatherback sea turtles. We helped establish the first permanent safe haven for leatherbacks in continental U.S. waters this year. The government designated nearly 42,000 square miles of critical habitat off the West Coast. The Pacific leatherback was also designated as California’s official state reptile following a bill sponsored and supported by Oceana with the support of thousands of California citizens and more than 30 conservation groups.

Chile Becomes First Country in World to Protect All Seamounts from Devastating Bottom Trawling!

Coral formations in Juan Fernandez archipelago lie among Chilean seamounts

As you enjoy those last holiday cookies before the New Year comes with its resolutions, we’d love to share one final present for you to enjoy: we are thrilled to announce that last week, the country of Chile became the first in the world to protect all of its seamounts from the devastating effects of bottom trawling! Oceana CEO Andrew Sharpless and actor and Oceana board member Ted Danson collaborated in an article published by the Huffington Post to share this excellent news with the world.


Seamounts are underwater mountain ranges that are home to an unbelievable array of sea creatures fed by the nutrient-rich water from the deep upwells. The destructive practice of bottom trawling, where large, heavy nets weighing as much as several tons each effectively clear-cut everything living on the seafloor,  causes more direct and avoidable damage to the ocean floor and its creatures than any other human activity in the world.  Although some of Chile’s seamounts have already been damaged or destroyed by the country’s fishing fleet, the December 20 decision closes any further trawling to Chile’s 118 seamounts until scientists have assessed these and other underwater ecosystems off the coast of Chile.

Harvard Dining Services Dishes Up Sustainable Seafood

It looks like r’s aren’t the only things getting dropped at Harvard: Over the last few years, Harvard University Dining Services (HUDS) has overhauled its operations to make its meals more ecologically friendly, and now unsustainable seafood is getting the chop.

In the last year, Dining Services began to examine the thousands of pounds of tuna, tilapia, salmon, and mahi-mahi being served to their seafood-hungry scholars, and realized that there was much room for change. These new changes reached their diners this fall, with students dining on new species like swai, and sustainable and regional versions of old favorites, like mussels from Prince Edward Island and shrimp caught in Maine waters.

“It’s part of our overall program in sustainable dining,” said David Davidson, managing director of HUDS. “We’re hoping we can come up with guidelines we can share with other schools.” To help guide them through the murky waters of seafood sustainability, Dining Services has enlisted the help of Barton Seaver, Washington DC chef, sustainable seafood advocate, National Geographic fellow, and frequent Oceana collaborator.

French Polynesia and the Cook Islands Create World’s Largest Shark Sanctuary

With as many as a third of all shark species in the world facing some threat of extinction, the future of sharks has been in peril for some time now. This month, however, French Polynesia and the Cook Islands have taken a stand for sharks, creating adjacent shark sanctuaries covering 2.5 million square miles of ocean – an area nearly equal to the continent of Australia! With this move, French Polynesia and the Cook Islands join Palau, the Maldives, Honduras, the Bahamas, the Marshall Islands, and Tokelau as countries that have created shark sanctuaries, more than doubling the area worldwide now off-limits to shark fishing. This largest sanctuary in the world also bans the possession, sale, or trade of shark products within its boundaries.


On December 6, French Polynesia created the world’s largest shark sanctuary at 1.5 million square miles, and the neighboring nation of the Cook Islands followed suit on December 19 with its designation of its entire exclusive economic zone – an area equal to the size of Mexico at 756,000 square miles -- as dedicated shark sanctuary waters. “We are proud as Cook Islanders to provide our entire exclusive economic zone…as a shark sanctuary,” Teina Bishop, Cook Island minister of marine resources told BBC News.

Endangered Sea Turtles Face Increased Threats

After a victory for Pacific sea turtles last week, here’s some not so good news. 

Two endangered species of sea turtle are facing an increased threat after the National Marine Fisheries Service (NMFS) approved a plan allowing a Hawaii-based shallow-set longline swordfish fishery to catch more endangered sea turtles while hunting for swordfish in the North Pacific Ocean.

Currently, regulations allow a capture, or “take,” of 16 endangered leatherback sea turtles and 17 endangered loggerhead sea turtles per fishery per year. If and when turtle catch limits are reached, the fishery must close for the year. However, the new rule, set to take effect November 5, will allow a 62 percent increase in allowable takes of leatherbacks for a total of 26 per year, and a 100 percent increase in the catch of loggerheads for a total of 34 per year. 

The timing for this approval is particularly paradoxical, as NMFS upgraded the status of the Pacific loggerhead sea turtle from “threatened” to “endangered” little more than a year ago, and designated almost 42,000 square miles of ocean waters off the coasts of California, Oregon, and Washington as critical habitat for leatherback sea turtles earlier this year. The leatherback sea turtle was also recently designated as the official state marine reptile of California.

Ben Enticknap, Pacific Project Manager for Oceana, said:

This decision is outrageous. On the one hand the federal government acknowledges Pacific leatherback and loggerhead sea turtles are endangered and that more needs to be done to protect them. At the same time they say it is okay for U.S. fishermen to kill more of them.”

We agree, it’s outrageous – and our campaigners are examining the available options in a plan to stop these measures before they take effect on November 5. We’ll keep you posted!
