Water and sediment characteristics influence the distribution of ghost shrimps (axiidea) in the Persian and Oman Gulfs.

Ghost shrimps (Crustacea: Decapoda) demonstrate remarkable levels of niche selection and habitat diversity. Due to their cryptic life style, interactions between ghost shrimp assemblages and environmental parameters that potentially shape their local distribution are poorly understood. In the present study, ghost shrimp assemblages from the Persian Gulf (PG) and the Gulf of Oman (GO) were investigated to assess the main drivers determining their assemblage structure along a wide niche type and at a large geographic scale.

A new species of the ghost shrimp genus Andamancalliax Sakai, 2011 from Iran (Crustacea: Decapoda: Axiidea: Eucalliacidae).

A new species of eucalliacid ghost shrimp is described from the Gulf of Oman, Iran. Andamancalliax poorei sp. nov.

Host specificity and microhabitat preference of symbiotic copepods (Cyclopoida: Clausiididae) associated with ghost shrimps (Decapoda: Callichiridae, Callianideidae).

We examined the host specificity of two ectosymbiotic Kossman, 1874 copepods Cyclopoida: Clausiididae on two co-occurrence species of host ghost shrimps. Our results revealed that both species of symbiotic copepod demonstrated extremely high host specificity. Moreover, within a single host shrimp species, each symbiont species displayed strong spatial patterns in microhabitat selection on their hosts' bodies.

A new species of ghost shrimp of the genus Michaelcallianassa Sakai, 2002 (Crustacea: Decapoda: Axiidea: Callichiridae) from subtidal waters of the Persian Gulf, Iran.

A third species of Michaelcallianassa Sakai, 2002 is described based on two specimens from subtidal waters of the Persian Gulf. Michaelcallianassa persica sp. nov.

A new species of Clausidium Kossmann, 1874 (Copepoda: Cyclopoida) associated with ghost shrimps from the Persian Gulf, including female-male interlocking mechanisms and remarks on host specificity.

A new clausidiid copepod was found associated with the ghost shrimp Neocallichirus jousseaumei (Nobili) in the Persian Gulf, on the Iranian coast. The new species shares the armature formula of swimming legs 2 to 4 with C. persiaensis, but can be easily distinguished from its congeners by unique characteristics of the females: the prominent spine on endopodal segment 1 of the antenna, the armature of the maxilliped, and the elongated basis of the swimming legs.

A new species of the ghost shrimp genus Neocallichirus Sakai, 1988 from Iran, and new record of N. manningi Kazmi Kazmi, 1992 (Decapoda: Axiidea: Callianassidae).

Two species of the callianassid ghost shrimp genus Neocallichirus Sakai, 1988 are newly recorded from Iran. Neocallichirus darvishi n. sp.

Callianassa ehsani, a new species of Callianassidae (Crustacea, Decapoda, Axiidea) from Gulf of Oman, Iran.

Callianassa ehsani sp. nov. is described as a new species from the Gulf of Oman, Iran.

Cheramus iranicus, a new species of ghost shrimp (Decapoda: Axiidea: Callianassidae) from the Persian Gulf, Iran.

A new species of callianassid ghost shrimp is described from the Persian Gulf, Iran. Cheramus iranicus sp. nov.
