A
A poriferan larva, composed of a hollow ball of cells, with one hemisphere ciliated (Ruppert & Barnes, 1994). +
Coastal salt water habitats with no surface connection to the sea. +
E.g. ''Ceratium'' spp. +
Having flagellate gametes of different size, shape or behaviour (from Bold, 1977 and Lincoln ''et al.'', 1998). +
Breeds every year but in one or more discrete periods initiated by some trigger (for example a lunar cycle). +
Breeds every year over an extended or drawn out period. +
Reproduction via single cells /eggs that are derived by mitosis (Barnes ''et al.'', 1993) - amictic. +
Swimming is effected one or more pairs of appendages (legs or paddles) e.g. the pleiopods of Isopod, Amphipod or Decapod crustaceans, or the legs of amphibious vertebrates. +
Alien and potentially invasive species that have accidentally escaped from containment/ aquaculture facility into the wild. +
Alien and potentially invasive species that have been intentionally introduced for aquaculture. +
Where the species alters boat traffic or impedes ability of boats to navigate waterways. +
a crystalline form of calcium carbonate, e.g. one of the constituents of mollusc shells. +
Having the shape or characteristics of a tree. +
Specialist - sea urchins +
Traits that describe specialized limbs or appendages used to catch or process food items. +
Haploid males develop from unfertilized eggs and diploid females from fertilized eggs (adapted from Lincoln 'et al.'', 1998). +
Jointed, arthrous (Holmes, 1979). +
E.g. wood, metal or concrete structures. +
A free-swimming tadpole-like larva of ascidians, characterized by a head (bearing internal organs and adhesive papilla) and tail (with notochord and neural tube) (Stachowitsch, 1992). +
Reproduction not involving the exchange of genetic material, amictic, individuals derived form a single parent (Barnes ''et al.'', 2006); not involving the fusion of gametes (Lincoln ''et al.'', 1998) +
Attached to the sediment surface e.g. by mucilagenous sheath such as used by necklace shells, and opistobranchs +
First free-swimming larval stage of the Holothuroidea. It is characterized by a continuous and curving flagellated band (Stachowitsch, 1992). +
Obligate self-fertilization (Lincoln ''et al.'', 1998) in which haploid eggs /gametes are produced by meiosis but diploidy is restored without fertilization. +
Self-feeding. An organism capable of synthesizing complex organic substances from simple inorganic substrates (Lincoln ''et al.'', 1998). +
B
Use of a length of silk to be carried by the wind (e.g. spiders) +
