Pueruli of Panulirus longipes bispinosus (Crustacea, Decapoda, Palinuridae) stranded on the beach of Kuroshima Island, Ryukyu Archipelago, southern Japan

Abstract

Stranded organisms were observed on the sandy beach of Kuroshima Island, Ryukyu Archipelago, in the early morning of 28 January 1993. Stranded organisms of 525 individuals were classified into 74 species. These organisms included 13 individuals of Panulirus pueruli, which were identical to P. longipes bispinosus. Kuroshima Island is located near Ishigakijima and Iriomote islands, Ryukyu Archipelago, where coral reefs develop. Coral reefs are common and develop in the Ryukyu Archipelago, southern Japan, with the exception of Yakushima and Tanegashima islands. Panulirus japonicus in Japanese waters has not been found in coral reef regions where P. longipes bispinosus are mainly found. The present study describes and identifies to species level puerulus specimens that were stranded on the beach of Kuroshima Island.

Identification of Mid- To Final Stage Phyllosoma Larvae of the Genus Panulirus White, 1847 collected in the Ryukyu Archipelago

“…in the spring sample, while aggregation of more advanced stage larvae of P. japonicus may be reasonable. Settlement of P. longipes has been observed to occur after October in Japanese waters (Tanaka et al, 1984;Tanaka, 1987;Yoshimura et al, 1999;Inoue et al, 2002). Our data coincide well with these field observations and indicate that the metamorphosis and settlement of P. longipes sspp.…”

Mortality Sensitivity in Life‐stage Simulation Analysis: A Case Study of Southern Sea Otters

“…Thus, the approach described in this paper would work best for cases in which death assemblage data truly represent a snapshot of causes of death (i.e., recoverability is not biased for age classes or cause). A review of the published literature suggests several species that would be amenable to this approach (e.g., manatees, Bonde [2000]; bottlenose dolphins, Ewing et al [2002], Eguchi [2002]; asteroids, Thorpe and Spencer [2000]; gastropods and bivalves, Inoue et al [2002], Warwick and Light [2002], Gonzalez et al [2001]; beetles, Connor [1988]; pronghorn, Lubinski and O'Brien [2001]). In addition, there are other candidates that could be examined from the fossil record (e.g., clams, Green et al [1984]; tetrapods, Rogers et al [2001];ungulates, Berger et al [2001]), which could shed light on demographic correlates of observed extinction patterns.…”
