New species of deep-sea shark and crab found off Australia

Meanwhile, it was Dr Andrew Hosie, curator of Aquatic Zoology from the Western Australian Museum, who was concerned in describing the brand new crab species. 

“The new species of porcelain crab lives a symbiotic life with sea pens, which are a group of soft corals related to sea fans, where they will hide among the ‘leaves’ of the host,” Dr Hosie mentioned. 

The crab is small, measuring at round 15mm in size, and is an opalescent white-yellow in color. This makes it well-adapted to cover inside the white leaves of its sea pen host. The new crab was discovered throughout surveys alongside the Ningaloo coast at depths to 122 metres.

“Porcelain crabs are known as filter feeders, feeding on plankton by using modified mouthparts with long hairs to sweep the water for small pieces of food such as plankton, rather than the typical crab method of grabbing and pinching food with their claws,” Dr Hosie continued. 

The lanternshark and porcelain crab are the most recent in a protracted line of almost 20 new species to have now been described with the assistance of specimens collected on the 2022 voyage, together with the Carnarvon Flapjack Octopus which was introduced earlier this 12 months. Incredibly, researchers estimate that there are probably as much as 600 new species nonetheless ready to be described from the voyage. 

The deep-sea continues to be largely unexplored and biodiversity surveys of those habitats are very important to extend our understanding of the marine life that dwells within the depths of our oceans.

Researchers anticipate to find extra species new to science throughout an upcoming CSIRO-led voyage on RV Investigator to survey the deep-sea biodiversity of the Coral Sea Marine Park for Parks Australia. The voyage brings collectively most of the similar researchers from the 2022 voyage, together with new collaborators and companions.

RV Investigator is a part of the Marine National Facility, nationwide collaborative analysis infrastructure funded by the Australian Government and operated by CSIRO, Australia’s nationwide science company.
