Marine mammal science is strengthened when we move beyond acknowledgement and toward responsibility, reciprocity, respect, and meaningful partnership.

Today is Red Dress day, a time for us to reflect on the fact that: -3 in 4 Indigenous women experience violence in their life, and that although we make up 2% of the population -40% of trafficking victims are Indigenous women. -murder is the 3rd leading cause of death for Native ♀️ #MMIW #MMIWG
A woman wearing a red shirt under a red attiqluq with white flowers holds a hand under earrings that look like red dresses. In some Indigenous tribes, red is a color that our ancestors can see. It's also a nod to the "what was she wearing" questions when a woman is sexually assaulted

Gray whales are dying in San Francisco Bay at an alarming rate – this isn’t normal
In the past, the gray whale population recovered fairly quickly. But data on baby whales show that isn’t happening, and a new study finds an alarmingly high mortality rate.

How incredible: “The full delivery took about 30 minutes. For hours afterward, pairs of whales held the baby above the water until it was able to swim… What struck the researchers was how many mother, sister and daughter whales united to support the new calf, even ones that weren’t related.”

Eastern Australian humpback whale population now well above pre-whaling levels, report finds - ABC News 🦑🧪🌎
abc.net.au
These whales were hunted to 150 individuals. Now there's 50,000 of them
Once hunted almost to extinction, the population of humpback whales currently migrating down Australia's east coast has bounced back and is now greater than before whaling.

The conservation world lost one of its guiding lights on Wednesday when renowned primatologist Jane Goodall passed away at 91. Over 65 years studying chimpanzees in the wild, Goodall proved that primates are a lot like people. But her impact goes far beyond chimps. 🧵
Close up of jungle plant life. There is a quote from Jane Goodall in white text over the image. It reads: "What you do makes a difference and you have to decide what kind of a difference you want to make."
