Biology
As the common name would suggest, this ghost shrimp was previously only known from Western Port however there is one record of the species from Swan Bay at the mouth of Port Phillip Bay. As in most ghost shrimps the claws are unequal but in this species alone, the moveable finger of the smaller claw is longer than the fixed finger. The species (as Eucalliax tooradin) was listed as "vulnerable" under IUCN criteria.
