Typhlocaris ayyaloni is a species of troglobitic shrimp in the family Typhlocarididae. [3]
This species grows to 4 to 5 cm in length and is blind. [4]
Typhlocaris ayyaloni species was discovered in 2008 in the Ayalon Cave in Israel, 100 meters below ground, with no natural access to the surface. It was found living in a small pool of sulphide-rich, brackish water. It is one of eight new species recently discovered in the area, the others being Tethysbaena ophelicola , Metacyclops longimaxillis , Metacyclops subdolus , Akrav israchanani (a land species, only found dead and also in other parts of the cave), Ayyalonia dimentmani (land species), Lepidospora ayyalonica (land species), and a still-unnamed species in the genus Collembola . [4]
This species is endangered as it is known only in the Yarkon-Taninim Aquifer, which is experiencing diminishing water levels. It is one of the main sources of water in Israel. [3]
