Welcome to the Chapple Big Fish Lab
In the Chapple Big Fish Lab, we study sharks and other large marine predators around the world focusing on their movements, behaviors and population dynamics. From South Africa to Australia to California, using state-of-the-art technology and techniques, we sample and electronically tag animals to gain insights into their lives when we aren’t there to observe them. In Oregon, we leverage partnerships with industry, management, science and local communities to study the sharks off our coasts to better understand the roles these animals play in our marine ecosystems and economies. Relatively little is known about how sharks affect our coastal ecosystems and communities in the Pacific Northwest, but here in the Chapple Big Fish Lab, we are changing that.
Did you know?
The Pacific Northwest is home to at least 15 species of sharks?! They range in size from the Brown Catshark (~2.2 ft or 65cm) to the Basking shark (>30 ft or 10m), with lots of sharks in between. To learn more about the sharks of the PNW visit our Sharks of Oregon page and explore the different species off our coast.
Shark Sighting in Oregon or Washington?
Tell us all about it on our Shark Sighting page to help us better understand when and where sharks are along the PNW coasts.
Chapple Big Fish Lab DEI Statement
In the Chapple Big Fish Lab we acknowledge there are systemic barriers and inequality in STEM fields- especially in shark science- and are committed to increasing representation of historically underrepresented groups in science. We are committed to inclusivity and strive to make access to research, opportunity and experience more equitable. We value diverse thought, experience, preferences and skills and feel we are stronger and more powerful as an inclusive community. We also acknowledge that we still do not fully understand the impact of historic and systematic inequality and as a lab we continue to actively evolve and work to fully represent the diversity of the broader global community.
As a largely field-based lab, we appreciate that field work can be intimidating and unwelcoming and we strive to create safe and accessible work space for all. We also participate in the FieldSafe program at OSU, to ensure that field work is safe to people of all identities.
Our Specific Actions
- We acknowledge the diverse cultural context of our work and integrate various types of knowledge and value in our interpretations and presentations
- We strive to offer opportunities to recruit and mentor students from diverse backgrounds and experiences.
- We use science communication to make science and research more accessible to people of all abilities Learn more about our ORSEA and OCEANTRACKS curriculum.

Despite a marked sexual segregation between populations tagging data has indicated that the Salmon sharks (Lamna ditropis) migrate between subartic and subtropical regions in the Pacific and have dramatic vertical movements within the water column as well
(Weng et al., 2005)
The Dwarf Lantern shark (Etmopterus perryi) earns its name by its ability to "glow" using photophores, organs that can emit light, along the bottom of its body. Their light up belly serves dual purposes, when in deeper waters with low light their belly will attract prey but in shallower, lighter waters the belly acts as camoflauge to hide them from the predators beneath them

Not all sharks need to "just keep swimming"! Some sharks use buccal pumping to pass water over their gills to ensure that they continue to recieve oxygen while lying on the ocean floor.
(Butler and Metcalfe, 1988)
