The Spot the Jellyfish campaign aims to increase awareness, especially amongst the younger generations, about the local diversity of jellyfish species, through a hands-on exercise involving the reporting of sightings of jellyfish that often swarm close to our shores and beaches. In so doing the initiative would be supplying useful data for local marine scientists and tourist authorities, through a citizen science approach... and aid to avoid those stinging jellies!

A stinging 'snake'....

This is the red-spotted siphonophore.....Forskalia edwardsii....a gelatinous colony made up of hundreds of individual, specialized polyps working together within the same gelatinous mass—some catch food, others handle defense or reproduction

Photos courtesy of veteran SCUBA diver Andrew Zammit, whom I thank....this colony was recently spotted in Maltese waters....and this colony, being a close relstive of the Portuguese man o' war, packs a dangerous sting.....

Return of the mauve stinger?

This Pelagia noctiluca individual was observed by veteran SCUBA diver Dr. Andrew Zammit, whom we thank, at a depth of 10m off the coast of Gozo…..this was the second summer in a row with almost no sightings of the mauve stinger jellyfish species, with most individuals seeking to venture into deeper waters to escape damage from the surface heat…..the species normally returns to the surface to spawn/reproduce in early winter…..one has to wait and see how this unfolds…..

Great photo indeed….

This is Geryonia proboscidalis…… It’s characterised by its translucent bell, or umbrella, that may reach a maximum diameter of 8cm, but its length can stretch up to a whopping 150cm!

It prefers warmer seas, which would explain its increasing appearances in the Mediterranean in the recent years, albeit still considered rare in these areas.

Salp bloom, off the western coast of the island of Gozo.....salps are actually much more evolved than your regular jellyfish and are closer to humans in terms of complexity....they help transfer carbon-rich waste from the surface to the bottoms of the sea, as they are constantly filtering food out of the water and hencrle they assist us in mitigating climate change....Spot the Jellyfish citizen science campaign....

Wow...this is a rare find indeed...the hula skirt siphonophore...Physophora hydrostatica....had recorded it for the first time from Maltese waters way back in 2018....stinging colony, like most siphonophores....heartfelt thanks to Cliff Pace and to Peter Wirth for such an interesting report......Spot the Jellyfish citizen science campaign....

Jellyfish in season.....the Mediterranean box jellyfish.....Carybdea marsupialis.....

This transparent, four-tentacle jellyfish, which is nowhere as venomous as its dreaded Australian cousin – the Australian box jellyfish (Chironex fleckeri) – prefers bays with a heavy boat presence and is common in places like Marsaxlokk, Pretty Bay, Qawra and Xemxija (i.e. it is limited to the eastern coastline of the islands)......its sting is best treated through the application of vinegar....this family of jellyfish (Cubozoa) have the best ‘eyesight’ of all, being able to form an image through a proper ‘eye, enabling the species to hunt generally at night......great photo by Danile de Castro, curator at the Malta National Aquarium, a dear friend whom I thank wholeheartedly....

Harmless comb jelly (ctenophore) bloom in our seas at the moment.....no need to panic, as these bioluminescent species are non-stinging, unlike regular jellyfish, by virtue of their sticky and NOT stinging tentacles......Spot the Jellyfish citizen science campaign.....
