New paper on sicklefin lemon sharks at Palmyra

We have been working at Palmyra atoll since 2003 and frequently see sharks; primarily blacktip, grey and whitetip reef sharks. We sometimes see other species such as Galapagos sharks and scalloped hammerhead sharks. However, we only started seeing sicklefin lemon sharks from 2010 onwards. Since that time the number of lemon shark sightings has really started to increase. We likely witnessed a recent colonization event as previously lemons were only recorded as far north as Fanning Atoll. We document the presence of lemon sharks at Palmyra in a new paper in Marine Biodiversity Records.
