As is customary at this time of year, hundreds of fried egg jellyfish (Cotylorhiza tuberculata) have been spotted and reported by the public as part of the Spot the Jellyfish campaign along different Maltese coastal areas, especially around Comino, the north coast of Gozo, Wied iz-Zurrieq and Marsascala. Testimony to the precise timing of the occurrence of the fried egg jellyfish swarms, the species is also known in Maltese as ‘tal-lampuki’ (in clear reference to the dolphin fish, which is caught at this time of year) as well by the descriptive monicker of ‘qassata’, which is a traditional Maltese pastry. Despite its size, the fried egg jellyfish is innocuous and its occurrence is short-lived, normally extending till the start of October at most.
Last year, thousands of the creatures were fished out of the water by boaters and bathers alike, who feared that they might be stung by the qassata, as it is known locally. The truth is that these creatures do not sting and are benign. Their stingers do not aggravate human skin and they are harmless.
Interestingly enough, juveniles of mackerel are frequently observed sheltering amongst the purple-tipped tentacles of the jellyfish. Way back in 1977, Guido Lanfranco reported the occurrence of large numbers of the fried egg jellyfish in Maltese bays, especially in those facing the south and south-east. The size of fried egg jellyfish aggregations so far are nowhere near the staggering dimensions of those observed in September of last year. Sightings of the fried egg jellyfish received so far make up five per cent of the over 300 jellyfish sightings reports received so far. A total of nine gelatinous plankton species have been recorded so far as part of the Spot the Jellyfish initiative. |
