A new tellinid species, Pharaonella amanyusp. n., is described from sand banks around Amami Islands, the Ryukyu Archipelago, in southern Japan. A molecular phylogenetic analysis suggests that this new species is closely related to P. sieboldii. This species has long siphons and lives buried deep in well-sorted white sand syntopically with Tonganaella tongana. These rare, large tellinid species ...

The Pycnogonida from Uruguayan waters are scarcely known, and their reports are markedly discontinuous. In this paper, several individuals of two previously unrecorded pycnogonids at the shallow rocky subtidal and lower intertidal fringes of Cerro Verde (Rocha, Uruguay) are reported. The specimens were assigned to Pycnogonum pamphorum Marcus, 1940 and Anoplodactylus petiolatus (Kroyer, 1844). T...

Heterodina Schotte & Kensley, 2005 is revised with Heterodina qeshmensis sp. nov., described from the subtidal zone of the Qeshm Island, southern Iran. Heterodina qeshmensis sp. nov. is characterized by: unornamented dorsal surfaces, wide and anteriorly concave epistome, and the appendix masculina with sub-parallel margins and not extending beyond the distal margin of the endopod. A key to the ...

Behavioral responses of organisms with respect to changing environment have a wide area research possibility. For palaeontologist it is challenge interpret the organism-sediment interaction from study trace fossils preserved in ancient rock record. The ethological significance which derived out different intentional or accidental activities may be within and largely controlled by substrate stab...

The genus Pullosquilla Manning, 1978, including P. litoralis, P. thomassini, and P. pardus, has been found in Taiwan for the first time. All three species live in a subtidal sand flat north of the Bitou fishing port within the Kenting National Park, Taiwan. Adult specimens were examined, illustrated, and photographed. The habitat, which all three species share, is described. The implication of ...
