Due to high levels of ciliate infestations can affect respiration, feeding, growth, survival and also irritation behaviour of larvae (zoea, mysis and post larvae) was observed. Protozoan diseases in P. monodon was global problem in hatcheries mainly affect the e...
Symbioses between chemoautotrophic sulfur-oxidizing (thiotrophic) bacteria and protists or animals are among the most diverse and prevalent in the ocean. They are extremely difficult to maintain in aquaria and no thiotrophic symbiosis involving an animal host has ever been successfully cultivated. In contrast, we have cultivated the giant ciliate Zoothamnium niveum and its obligate ectosymbiont...
Abstract Shore-based submersible operations, from 2006 to 2020, have allowed us examine megabenthic assemblages along the island margin of Isla de Roatán depths about 150 750 m, including repeated observations same organisms. These dives were used photo-document a diverse benthic assemblage and observe health condition sessile fauna in well-explored but relatively undocumented area Mesoamerican...
