  • Relative Growth and Sexual Dimorphism in the Red Frog Crab Ranina Ranina (Decapoda: Raninidae)
    Nippon Suisan Gakkaishi 59(12), 2025-2030 (1993) Relative Growth and Sexual Dimorphism in the Red Frog Crab Ranina ranina (Decapoda: Raninidae) Megumi Minagawa* (Received July 9, 1993) The relative growth of several body parts and the morphology of pleopods were examined in reared and captured individuals of Ranina ranina. Sexual dimorphism occurred in the pleopods at instar I, on the abdomen of individuals over 34mm carapace length, and on the cheliped in individuals over 70mm carapace. In females puberty molt was estimated to occur at 40-45mm carapace length, using the relative growth of abdomen width . In males the relationship between dactylus or propodus length of the cheliped and the carapace length was described by two or three power regression equations. The point of contact of the logarithmical ly transformed linear equations was 26 and 74mm in dactylus length and 73mm in propodus length. A growth-reproduction model of R. ranina based on changes in the relative growth is discussed. The red frog crab Ranina ranina Linnaeus is a commercially important crab found on sandy bot toms in the Indo-West Pacific.1,2) Some aspects of the reproductive biology of R. ranina have been reported, including information on the reproduc tive cycle, ovigerous season, and minimum size to maturity in Hawaii, Japan, the Philippines, and Australia.3-8) However, information on the re lationship between growth and reproduction is fragmentary. The relative growth of several body parts shows different patterns, associated with sex and maturity in Decapoda.9,10) Hartnoll11) summarized relative Fig. 1.

  • (Linnaeus) . (Brachyura
    Pacific Science (1976), Vol. 30, No.2, p. 131-145 Printed in Great Britain Sex Ratio, Size at Reproductive Maturity, and Reproduction of the Hawaiian Kona Crab, Ranina ranina (Linnaeus) . (Brachyura, Gymnopleura, Raninidae) I ANN FIELDING2 and SA~1UEL R. HALEy3 ABSTRACT: Sex ratio and size at reproduction of Ranina ranine (Linnaeus) in Hawaii were investigated. A sample of 1596 Kona crabs collected over 1 year in Hawaiian waters was examined to determine sex ratio and size at reproduction. Males constituted 55 percent of the overall samples and a similar proportion in all size classes. Males attain a larger maximum size than do females and have mature spermatozoa when their carapace length exceeds 60 mm. Secondary sexual characteristics in the male develop at a carapace length ofabout 75 mm. Females are ovigerous from May to September. Most ovarian growth occurs between February and May. In May, at the beginning of the spawning season, the number of eggs ovulated is a function of maternal body size: a 25-percent increase in carapace length is associated with a 200-percent increase in number of eggs ovulated. This is not so later in the spawning season (August-September). Larger females appear to ovulate at least twice each season, withthe primary effort going into the first ovulation. The smallest 5-mm size class in which at least 50 percent of the females are ovigerous during the spawning season is 70.0-74.9 mm in carapace length. The mean minimum size of ovigerous females is 86 ± 8 mm in this dimen­ sion. The spermatheca in females is open to the outside at carapace lengths exceed­ ing 60 mm.

FoR'r~Y, London* With 12 figures K u r z f a s s u n g: Die Typusart der ordovizischen Trilobiten-GattungSymphysurus, S. palpebrosus DAL- MAN 1827, wird anhand des schwedischen Typusmaterials neu beschrieben. Die Gattung tritt, verglichen mit der damals meist engeren geographischen Bindung anderer Trilobiten, in auffallend welter Verbrei- tung auf, n~imlich sowohl in peripheren Bereichen des Skandinavischen Paliiokontinents als auch des (heute siideuropliisch-vorderasiatischen) Gondwana-Nordsaums, und zwar in relativ bathyaler Fazies. S. palpebrosus besitzt an enge Einrollung angepaflte Organisationsmerkmale. Die funktionsmorpho- logische Analyse zeigt, daft sich diese Art zeitweilig in bumastoider Stellung, also mit eingegrabenem Py- gidium und Thorax, aber freiem Cephalon im Sediment aufhielt, der Nahrungssuche aber auflerhalb ihres Baus nachgegangen sein diirfte. Die Funktion der auf manchen Partien der Cuticula wohl ausgebildeten Terrassenlinien ist noch immer ein in mancher Hinsicht offenes Problem.

Abstract: The type of the widespread Ordovician trilobite Symphysurus, S. palpebrosus DALM^N, 1827, is redescribed from the type Swedish material; its distribution is documented. Symphysurus is one of very few trilobite genera to be found in both Ordovician Baltica and Gondwana, in more peripheral sites relative to the platform areas.

The description of the morphological features of the species is given. Spanner crabs inhabit coastal waters of several coun- tries in the Indian and Pacific oceans, from the east coasts of southern Africa to Hawaii and the Great Barrier Reef. They prefer bare sandy areas and inhabit intertidal waters to depths more than 100m. They aggregate to spawn during the warmer months and mate at any stage in the moult cycle (Brown, 1986) and females store the sperm until the eggs are extruded.During spawning the females often bury themselves to incubate and protect the eggs. Large females produce at least 2 batches of eggs, each season with an average number of 1,20,000 per batch. The eggs remain attached to the female for 4 – 5 weeks before hatching (Brown, 1986). They pass through 8 larval stages during the following 5 to 8 (longest in higher latitudes) weeks of their life, and then they settle before metamorphosis to the recognizable spanner crab form Fig. 1. Ranina ranina landed at Pamban (Brown, 1986).

SQUIRES Department of Geological Sciences, California State University, Northridge 91330 ABSTRACT—Rare specimens of the nautiloids Nautilus and Aturia and extremely rare specimens of a sepiamorph sepiid are described from the late Eocene Hoko River Formation, northern Olympic Peninsula, Washington. The well-preserved partial phragmocones are from channel-fill clastics deposited on the inner and middle slopes of a submarine-fan system. The Nautilus specimen is allied to N. cookanum Whitfield from middle Eocene strata, New Jersey, and is probably conspecific with Nautilus sp. (Miller) from late Eocene strata, northwestern Oregon, both of which were previously assigned to Eutrephoceras. This is the first record of Nautilus in the northeastern Pacific. The Aturia specimen is tentatively identified as A. cf. A. alabamensis (Morton), a species previously only known from late Eocene strata in the Atlantic-Gulf Coastal area and northeastern Mexico. Aturia alabamensis may be the same as numerous Eocene North American aturiid species. The two sepiamorph sepiid specimens resemble Belosepia Voltz but are probably generically distinct.
