JOURNAL FREE ACCESSGeographic variation between populations of the anemonefish, Amphiprion clarkii (Bennett) from the Bonin Islands, Yaeyama Islands, Okinawa, and Miyake-jima, Japan, is described, and relationships between color patterns and social dominance of the species at Miyake-jima are discussed.Yaeyama populations show the greatest degree of variation in color, but sexual dichromatism is not always pronounced.In Okinawan populations, adult males can be consistently recognized by orange borders on the caudal fin, compared to uniformly yellow caudal fins in adult females.Populations from Kyushu to Miyake-jima show subdominant fish of both sexes displaying orange caudal borders, similar in appearance to Okinawan males.Dominant males have solid orange or nearly solid orange caudal fins, whereas dominant females show pale yellow caudal fins.Anal and pelvic fins darken with dominace.Miyake fish are slightly larger than those from Okinawa, with slightly greater meristic counts and narrower body bars.Variations in color patterns appear to be related to selective pressures imposed by differences in habitat.A melanistic form occurs in the Bonin Islands.Sexual dichromatism is not present in populationsfrom the Bonin Islands.Melanistic individuals from the Bonin Islands inhabit Radianthus anemones. Fish inhabiting the anemone, Stoichactis haddoni, at Okinawa and Miyake-jima are of the dark phase.View full abstractDownload PDF (9126K) -

JOURNAL FREE ACCESSThe reproductive behavior of the anemonefish, Amphiprion clarkii (Bennett) is described from the island of Miyake-jima, Japan.Host anemones of the genus Parasicyonis provide nesting habitats which vary considerably in size, resulting in differences in social behavior.Agonistic behavior is more pronounced in large, crowded colonies than in small ones with a single dominant pair and 2-3 subdominant fish.Only dominant fish are sexually active.Courtship behavior is initiated by the male and consists merely of nest cleaning, sometimes with bodies touching, and nipping at the tentacles of the anemones.Head-shaking, dorsal and ventral leanings, and jawclicking, often described as courtship displays, are considered here as agonistic behavior, occurring more regularly in newly established pairs where the pair bond is weak than in established“veterans” . Spawning takes place between 9 AM-3 PM.The male assumes most of the responsibility for egg-care, the female only rarely fanning eggs.Nocturnal egg care is lacking except on the night of hatching.Eggs hatch between 34-70 min after sunset.View full abstractDownload PDF (5529K) -

JOURNAL FREE ACCESSThe osteology, mode of life, and reproduction of Hypoptychus dybowskii were compared with a species of the family Ammodytidae, two species of the family Aulorhynchidae, and a species of the family Gasterosteidae.Hypoptychus resembles gasterosteids and aulorhynchids in osteological features, mode of life, and reproduction.Although Hypoptychus resembles ammodytids in higher number of vertebrae, the family Hypoptychidae should be transferedfrom the suborder Ammodytoidei of the order Perciformes to the suborder Gasterosteoidei of the order Syngnathiformes.View full abstractDownload PDF (4440K) -

JOURNAL FREE ACCESSPostlarvae of the gonostomatid fish, Pollichthys mauli (Poll), are described and the early life history is studied for the first time.It is shown that sequence of development is divided into two distinct forms, i.e., white-bait form changes into adult form through marked metamorphosis. White-bait larvae are slender and are devoid of pigmentation except eyes;eyes are oval and possess underlying choroid tissue;anus and anal fin are situated very posteriorly of the body.Buds of photophores appear late in the larval stage.Adult form shows the features of mesopelagic inhabitants; photophores develop prominently;forebody is elongated and/or deepened;pigments spread on the head and along the back;eyes are rounded and lost the choroid tissue;anus and anal fin are set anteriorly.Developmental stages are subdivided as follows: white-bait form, into prelarval (not included in this study), postlarval (this stage is further separated into early, middle, and late stages), and metamorphic stages;adult form, into juvenile and adult stages.View full abstractDownload PDF (2126K) -

JOURNAL FREE ACCESSRecently I examined one specimen of a scorpaenoid fish which was identified Snyderina yamanokami Jordan et Starks, 1901(Japanese name:Yamahime).This specimen was taken from off Amami-Oshima, Kagoshima Prefecture, on June 1972 and has been deposited in the collections of the Kochi Senior High School (cat.no.15082).The holotype of this species is 217 mm in standard length, collected from Kagoshima, Japan.No other collecting record are available.I wish to report here the occurence of this congiopodid species and its external characters.View full abstractDownload PDF (416K) -
