Abstract This study contributes a preliminary checklist of commercial marine shrimps collected along Peninsular Malaysia coastal waters. Samples collection were carried out between November 2021 to August 2022 either by using bag-net or purchasing from local landing sites if their capture locations could be confirmed. In total, 375 individuals 18 species and 7 genera, belonging the Family Penae...

Recordings of narwhal (Monodon monoceros) echolocation signals were made using a linear 16 hydrophone array in the pack ice of Baffin Bay, West Greenland in 2013 at eleven sites. An average -3 dB beam width of 5.0° makes the narwhal click the most directional biosonar signal reported for any species to date. The beam shows a dorsal-ventral asymmetry with a narrower beam above the beam axis. Thi...

A bioenergetic model for two narwhal (Monodon monoceros) sub-populations was developed to quantify daily gross energy requirements and estimate the biomass of Greenland halibut (Reinhardtius hippoglossoides) needed to sustain the sub-populations for their 5-month stay on wintering grounds in Baffin Bay. Whales in two separate wintering grounds were estimated to require 700 tonnes (s.e. 300) and...

Isopod parasites of the subfamilies Ioninae and Pseudioninae infest the branchial chambers of brachyuran crabs. In total, 19 species of parasitic isopods infest crabs from China; they belong to 6 genera from the Ioninae and 1 genus from the Pseudioninae. Specifically, the following genera are represented: Allokepon Markham, 1982 (three species), Apocepon Nierstrasz and Brender à Brandis, 1930 (...
