Recently, a new article was published by Dr. Danny Golani, the curator of the fish collection at the Hebrew University's National Nature Collections - an up-to-date list of the fish species of the Mediterranean Sea of Israel. The list includes 469 fish species, an addition of 62 species since the previous list published in 2005. Most of the species added to the list - 38 of them - are immigrants (invaders) to the Sapsians (named after Ferdinand de Lesseps - thinker and initiator of the digging of the Suez Canal), which came from the Red Sea to the Mediterranean Sea through the Suez Canal.

Dr. Golani speculates that the dramatic increase in the Lessepsian species - 2.5 species every year during the last 15 years - is probably due to the increase in water flow between the Red Sea and the Mediterranean Sea, following the recent opening of the new 72 km "parallel canal" and the expansion of other sections in the Suez Canal. In other works, many species of Sapsians that are not fish have also been described, such as the jellyfish from the wandering filamentous species.
In the photographs - two examples of species that migrate to the Mediterranean Sea:
