Littoral Pycnogonida from Oman

Magnetic susceptibilities of chromites from Oman

MINERALOGICAL and physical characteristics of natural chromites from Oman ophiolites have been recently investigated using M6ssbauer spectrocopy (MS), X-ray diffraction (XRD) and Scanning electron microscopy (SEM) by Al-Alawi et al. (1996). From the MS analysis together with the SEM data, they derived the chemical formula for specimens collected from two separate chromite deposits named Tawiyah...

The Swimming of Nymphon Gracile (pycnogonida)

Most arthropods move by means of metachronal waves of activity passing over the paired appendages, and the resulting gaits have been studied extensively, with regard both to their locomotory effectiveness (Manton, 1953) and to co-ordination (Beth6, 1930; von Hoist, 1935). Most attention has been focused on terrestrial or benthic arthropods and the mechanism of co-ordination of insect walking es...

Terrestrial Ages of Some Meteorites from Oman

A new species of Melithaea (Anthozoa, Octocorallia, Melithaeidae) from the Oman Sea, off Oman

A new species, Melithaea davidisp. n., is described from the eastern coast of Oman, Oman Sea, in the northwestern Indian Ocean, where it differs from its congeners in lacking capstans and having predominantly spindles in the coenenchyme. A molecular phylogenetic analysis of mtMutS and 28S rDNA genes suggests that it is genetically distinct from similar species in the Red Sea. Furthermore, a spe...

A new species of Hemichela Stock, 1954 from the South China Sea (Arthropoda, Pycnogonida, Ammotheidae)

A new species of pycnogonid collected by the Chinese research vessel, R/V HY IV, during deep sea cruises to the South China Sea in 2013, is described. The new species, Hemichela nanhaiensis, obtained from more than 1300 m depth, is distinguished from the other two species in the genus by the characters of the chela dactylus with 12 denticulations on the inner margin and by the presence of talle...
