Harbor Branch Oceanographic Institution, Fort Pierce, Florida. U.S.A. (Received 24 March 1987; revision received 9 December 1987; accepted 22 December 1987) Abstract: In the San Juan Islands, Washington, solitary ascidians .that occur in dense monospecific aggregations demonstrate gregarious settlement as larvae, whereas species that occur as isolated individuals do not. All gregarious species reject their own eggs and larvae as food, but nongregarious species consume conspecific eggs and larvae. Moreover, the rejection mechanism is species-specific in some cases. Correla­ tion analysis suggests that species specificity of the rejection response has a basis in siphon diameter, egg density, and larval size, but not in number of oral tentacles, or tentacle branching. One strongly cannibalistic species, Corella inflata Huntsman, avoids consuming its own eggs and newly released tadpoles by a unique brooding mechanism that involves floating eggs, negative geotaxis after hatching, and adult orientation. Key words: Ascidian; Cannibalism; Distribution; Larva; Settlement behavior INTRODUCTION Many sessile marine invertebrates, including filter-feeders such as mussels, oysters, barnacles and ascidians, occur in discrete, dense aggregations.

  • Observations on the Gorgonian Coral Primnoa Pacifica at the Knight Inlet Sill, British Columbia 2008 to 2013

    Observations on the Gorgonian Coral Primnoa Pacifica at the Knight Inlet Sill, British Columbia 2008 to 2013

    Observations on the Gorgonian Coral Primnoa pacifica at the Knight Inlet sill, British Columbia 2008 to 2013 By Neil McDaniel1 and Doug Swanston2 May 1, 2013 Background The fjords of British Columbia are glacially-carved troughs that snake their way through the coastal mountains, attaining depths as great as 760 m. Knight Inlet is especially long, extending 120 km northeast from an entrance located 240 km northwest of Vancouver, near the north end of Vancouver Island. Despite a maximum depth of 540 m it has a relatively shallow sill lying between Hoeya Head and Prominent Point with a maximum depth of only 65 m. Due to the shallow nature of the sill, tidal currents frequently exceed 0.5 m/second. ____________________ 1 [email protected] 2 [email protected] 1 The site has been of particular interest to oceanographers as the classical shape of this sill results in the presence of internal gravity waves and other interesting hydraulic phenomena (Thompson, 1981). As a result, university and federal government scientists have undertaken a number of oceanographic surveys of these features. In the early 1980s researchers surveying the depths of Knight Inlet with the submersible Pisces IV encountered large fans of gorgonian coral on the flanks of the sill at depths of 65 to 200 m (Tunnicliffe and Syvitski, 1983). Boulders of various sizes were found scattered over the sill, many colonized by impressive fans of Primnoa, the largest 3 m across. The fact that this gorgonian coral was present was noteworthy, but the scientists observed something else extremely curious. Behind some of the boulders were long drag marks, evidence that when the coral fan on a particular boulder became big enough it acted like a sail in the tidal currents.

CALIFORNIA MARINE FISH LANDINGS FOR 1972 LEO PINKAS Marine Resources Region 1.1. INTRODUCTION The protection, propagation, and wise utilization of California's living marine resources (established as common property by statute, Section 1600, Fish and Game Code) is dependent upon the welding of biological, environment- al, economic, and sociological factors. Fundamental to each of these factors, as well as the entire management pro- cess, are harvest records. The California Department of Fish and Game began gathering commercial fisheries land- ing data in 1916. Commercial fish catches were first published in 1929 for the years 1926 and 1927. This report, the 32nd in the landing series, is for the calendar year 1972. It summarizes commercial fishing activities in marine as well as fresh waters and includes the catches of the sportfishing partyboat fleet. Preliminary landing data are published annually in the circular series which also enumerates certain fishery products produced from the catch.

Internal phylogeny and relationships between Styelidae and Pyuridae 37 were inconclusive however. In order to clarify these points we used mitochondrial and 38 nuclear sequences from 31 species of Styelidae and 25 of Pyuridae. Phylogenetic trees 39 recovered the Pyuridae as a monophyletic clade, and their genera appeared as 40 monophyletic with the exception of Pyura.
