Taxonomy is recognized as an important infrastructure of biodiversity research and nature conservation. However, taxonomy itself has been declining in terms of number of taxonomists and expertise covering various taxonomic groups. The animal taxonomy in Japan is not an exception. How can animal taxonomists improve this situation? This paper provides several suggestions including basic assessments on animal taxonomy in Japan (e.g., number of taxonomists and number of specialists on various animal taxa), making a nation-wide list of animals in Japan, research projects by groups of different specialists covering different animal taxa, and using biodiversity databases to implement new researches on distribution and phylogeography.
There have been few reports on the ecology of settled larva of the feather star in the field. In order to identify the natural substrate on which the larva of feather star settles, submarine explorations were performed once a month from June 2009 through to July 2010 at Futatsujima-Islands and Koajiro Bay in Misaki, Kanagawa Prefecture, Japan. From March to July, settled larvae of Antedon serrata were observed at a depth of 3.5 to 8m at the holdfast of Ecklonia cava and Eisenia bicyclis. Up to 120 larvae clung to the basal part of a holdfast. The larvae observed on June 26th, 2009 were in different developmental stages from cystidean to late pentacrinoid. This is the first report that the larva of A. serrata settles preferentially on the holdfast of the brown algae in the field.
Ten carangid specimens belonging to the genus Selar, collected by small set net at Kadogawa Bay, Miyazaki Prefecture (eastern coast of Kyushu Island), Japan, were identified as Selar boops (Cuvier in Cuvier and Valenciennes, 1833), on the basis of scales in curved part of lateral line 22-24 and chord of the curved part of lateral line 2.2-2.7 times in straight part. These specimens represent first record of the species from Japan. Specimens are described and a new Japanese name "Teru-meaji" is proposed for the species.
A single specimen of a carangid fish, Alepes kleinii (125.1mm in standard length), was collected by a small set net at depths shallower than 8m off the northeastern Kadogawa Bay, Kadogawa-cho, Miyazaki Prefecture, Pacific coast of Kyushu Island, Japan. Alepes kleinii is distinguishable from its congeners by the following combination of characters: two rows of small conical teeth arranged irregularly in a narrow band on upper jaw but those on lower jaw in a single series, a diffuse dusky blotch present on upper margin of opercle, and straight part of lateral line starting behind below origin of second dorsal fin. The specimen represents the reliable record of the species from Japan.
