You may not know the name of Helen Battle, but she had a big impact on the history of marine biology in Canada. The first Canadian woman to earn a PhD in marine biology, she taught over 4,500 students in her half-century career. This is her story. 📸 Western University 🧵 1/8

talking about vertebrates like how people talk about invertebrates: I saw a blue jay today! This beautiful bird is native to North America. While its bite is painful, it is nonvenomous & harmless to humans. Unlike most tetrapods, the gray squirrel broods its young internally and gives live birth!

Earthenware crab vessel with two spouts flanking a round handle on its back. It's painted a reddish-orange color and its stumpy claws are closed in front of its cute little face. It's standing up on its six non-claw legs, which are also stumpy. Insanely adorable.
