CITIZEN SCIENCE
Sunfish in the NE Pacific - California to Alaska

Background

The first ever report of a Hoodwinker sunfish (Mola tecta) in California in 2019, less than two years after the species was first described in New Zealand, came as a huge surpriseMola tecta was thought to be a temperate southern hemisphere species with the warm equatorial waters presenting a major barrier to its distribution. Only lost individuals were thought to turn up in the northern hemisphere on an extremely limited basis. However, since 2019, numerous hoodwinkers have “surfaced” in the NE Pacific. What on earth are they doing there?? Have they always been there, or did they arrive recently? Are they a signal of our changing climate, or is the NE Pacific a natural range extension for this species?

Whatever the answer, it is now clear that Mola tecta has a presence in the Californian Current System beyond infrequent, chance occurrences. Here, they co-occur with the “usual sunfish suspect” in these waters, the famous Ocean Sunfish, Mola mola

To better understand the spatial extent of Mola tecta in the NE Pacific, we are using crowd-sourced information from citizen scientist to collect and curate sunfish photos from California to Alaska. The information is used to map species level occurrences of both Mola tecta, and its congener, Mola mola. Our aim is to better understand how common Mola tecta is in this area, relative to Mola mola, and (through genetic analysis) examine the connectivity with Mola tecta in South America and New Zealand.

Submit sunfish photos (all species!) from California, Oregon, Washington State, British Columbia and Alaska. We are interested in all sunfish photos and video – of any sunfish species – not just Mola tecta.

We need data, but we also need software! Please support our endeavours to raise funds for software licenses to develop a robust database, and manage the many citizen science photo submissions. All donations are hugely appreciated, big or small or tiny. Thank you!
