On Feb. 11, 2015, Barbara Lloyd, Founder of Ocean Sanctuaries, presented an abstract called: IDENTIFYING SEVENGILL SHARKS IN SAN DIEGO WITH ‘WILDBOOK

Barbara Lloyd and Michael Bear, Citizen Science Director, Ocean Sanctuaries.org;

“Our goal is to attempt the identification of Sevengill sharks (Notorynchus cepedianus) that may be returning to San Diego from year-to-year, using the pattern recognition algorithm provided in “Wildbook,”a web-based application for wildlife data management, designed by Jason Holmberg. “Wildbook” has been successfully used to ID Whale Sharks (Rhincodon typus) by their spotting patterns.1, 2Sevengill sharks (Notorynchus cepedianus), are currently listed as Data deficient (DD) on the IUCN Red List: This assessment is based on the information published in the 2005 shark status survey (Fowler et al. 2005).3

The genesis of this project was the apparent increase of encounters and sightings reported by divers with this species in the San Diego area, from 2009 to the present, to provide a long-term population dynamics study to examine the possible reason for this, as well as to provide a baseline study for future researchers.”
