Education, Science

I recently unveiled a new tier of Patreon rewards: 3D printed shark and ray models! For $17 per month, you will get a monthly 3D printed educational model of different shark or ray parts in the mail, and you’ll be supporting my efforts to provide these models to schools for free.

The first month’s reward comes from one of the most (in)famous sharks of all time, Carcharocles megalodon! The first 3D printed Patreon reward is a meg tooth, an exact copy of the meg tooth that has been used to educate thousands of students at UBC’s Beaty Biodiversity Museum!

Here are some things to know about Carcharocles megalodon!

Have you heard the good news about shark populations? Shark population increases are cause for #OceanOptimism

February 28, 2018February 28, 2018 David Shiffman

Conservation, Science

Did you know that some shark populations have declined due to overfishing? Did you know that some once-declined shark populations have recovered? If you’re like my twitter followers, it’s likely that you’ve heard the bad news, but have not heard the good news.

Why does this matter?
It’s important to share bad news so that people know there’s a problem, and that we need to act to solve that problem. However, it’s also important to share good news so that people know that a problem is solvable! This idea was behind the birth of the #OceanOptimism online outreach campaign.

Dear Shark Man, do open ocean sharks use nursery areas?

February 14, 2018February 14, 2018 David Shiffman

Welcome to Dear Shark Man, an advice column inspired by a ridiculous e-mail I received. You can send your questions to me via twitter (@WhySharksMatter) or e-mail (WhySharksMatter at gmail).

Dear Shark Man,

I know that sharks that live close to the coast sometimes use “nursery areas” when they are young. Do open ocean sharks also use nursery areas?
Sincerely,
Nosey in North Carolina
