Chelon auratus
Silvery schooling fish logged at 22 sites in Murcia, Spain, in cool water down to 9.7C. Here's how to spot one and where divers find them.
Slim, torpedo-shaped body around 43 cm with bright silvery sides and a faint golden-yellow blush on the cheek and gill cover that gives the species its name. Swims in loose schools just off the bottom or mid-water, often near harbours, river mouths and shallow rocky ground. Look for the small mouth, blunt snout and the way the whole school wheels together rather than scattering individually.
Divers typically encounter it moving in loose, unhurried schools over shallow rocky bottoms, often close to the surface where light penetrates the water column. It tends to keep some distance from divers rather than approach, drifting off as a group if you get too close. Most sightings come from casual encounters on shallower dives rather than dedicated searches, suggesting it's a background species you spot while looking at other things.
Golden grey mullet feed by grazing algae and organic detritus off rocks and sediment, making them one of the reef's quiet clean-up crew rather than active hunters.
Sightings don't show a clear seasonal pattern, and the species tolerates a wide temperature range from 9.7 to 20.7C, so it's worth watching for on any dive in Murcia year-round.
Reef neighbours a diver could mistake it for. Use the identification notes above to tell them apart.
Currently a reliable sighting only in Spain, with every logged encounter coming from sites in Murcia. If you're diving that stretch of the Spanish Mediterranean coast, keep an eye on shallow rocky reefs and harbour margins where schools of mullet cruise the water column.
Mapping where Golden Grey Mullet is logged…
The strongest logged population is in Murcia, Spain, where divers have recorded it at a range of sites. Outside that region, confirmed sightings are sparse in the current data.
There's no strong seasonal pattern in the sightings, and the species copes with water from roughly 10 to 21C, so it can turn up on dives in Murcia at any time of year.
Look for a slim, silvery fish around 43 cm long with a subtle golden tint on the cheek, swimming in a loose school near the bottom or mid-water on rocky ground.
They typically reach around 43 cm in length, making them a mid-sized schooling fish rather than a giant.
No, they pose no danger to divers. They're a calm, schooling species that keeps its distance rather than interacting.
