Association with vessel vectors

Actual evidence of being found in samples in a particular vector from any world region.

Anchor and anchor chains. Organisms found on anchors, anchor chain or within attached sediments, including anchor chain lockers.

Ballast water. Ballast water means water with its suspended matter taken on board a ship to control trim, list, draught, stability or stresses of the ship.

Biofouling. Biofouling means the accumulation of aquatic organisms such as micro-organisms, plants, and animals on surfaces and structures immersed in or exposed to the aquatic environment. Biofouling can include microfouling and macrofouling.

Biofouling comprised of only microfouling is commonly referred to as a slime layer.

Allogenic ecosystem engineers. Organisms which modify the environment by causing physical state changes in biotic and abiotic materials that, directly or indirectly, modulate the availability of resources to other species (e.g. excavating deep burrows which other organisms co-occupy, damming the water flow, etc).

Keystone species. A keystone species is crucial in maintaining the organization and diversity of its ecological community, by determining the types and numbers of other species.

Semelparous. Organisms breeding once in their lifetime.

Reproductive type

Asexual. Budding, Fission, Fragmentaion, including parthenogenesis. A form of asexual multiplication in which:
a) a new individual begins life as an outgrowth from the body of the parent. It may then separate to lead an independent existence or remain connected or otherwise associated to form a colonial organism;
b) the ovum develops into a new individual without fertilization;
c) division of the body into two or more parts each or all of which can grow into new individuals is involved.

Self-fertilization. Selfing or autogamy. The union of a male and female gamete produced by the same individual.

Sexual. Permanent hermaphrodite, Protandrous hermaphrodite, Protogynous hermaphrodite, Gonochoristic.
Capable of producing both ova and spermatozoa either at the same time. A condition of hermaphroditism in plants and animals where male gametes mature and are shed before female gametes mature or vice versa.
Having separate sexes.

Salinity

1. Limnetic [<0.5psu]
2. β-Oligohaline [0.5-3psu]
3. α-Oligohaline [3-5psu]
4. β-Mesohaline [5-10psu]
5. α-Mesohaline [10-18psu]

Gregarious. Organisms living in groups or communities, growing in clusters.

Solitary. Living alone, not gregarious.

Sub-species level

A geographical subset of a species showing discrete differences in morphology, coloration or other features when compared with other members of the species. Subspecies may also differ in their habitat or behavior, but they can interbreed. Often the lowest taxonomic level within a classification system.

Synonym

Toxicity

Poisonous. An organism capable of producing poison that gains entry to another organism body via the gastrointestinal tract, the respiratory tract, or via absorption through intact body layers.

Comments:
The invasion of the Pacific oyster has diverse effects on native parasite-host interactions and among those is a potential spillback of the shell-boring polychaete Polydora ciliata to native molluscs. This worm is a shell parasite that drills holes in the shells of epibenthic bivalves and gastropods, and infected organisms have to spend energy on repairing these holes.
P. ciliata is a polydorid polychaete (Spionidae) with a pelagic larval stage and has probably a preference for mollusc hosts inhabiting the lower intertidal and subtidal.

Comments:
The worms are either male or female; sperm is liberated into the water column and drawn into the burrow of the female by means of the respiratory current. Up to 60 eggs are enclosed in a capsule, and several capsules are suspended by threads inside the female's tube.
Developmental trait (?) Brooding

Wilson, W. H. 1991. Sexual reproductive modes in polychaetes: classification and diversity. Bulletin of Marine Science, 48(2), pp. 500-516.

Comments:
The eggs hatch in about one week and are planktonic for up to six weeks before settling. When the worms bore into the shells of oysters, mussels and periwinkles, they do not feed on the mollusc's soft parts, but they weaken the shell and make the mollusc more vulnerable to attack by crabs and other predators.

Comments:
When feeding, the worm extends its head out of the tube and uses its two long palps to feed on detritus. It has been observed feeding on dead barnacles and other small dead invertebrates, and can also filter plankton from the water.

Comments:
The burrow of P. ciliata is U-shaped, and the presence of these worms can be recognised by the sets of small, double perforations they make. The worm is believed to burrow by abrading the substrate with its bristly chaetae, but there may also be some chemical action involved in burrowing.

Comments:
Polydora ciliata is a spionid polychaete found below mid-tidal level burrowing in a variety of rocks all of which contain calcium carbonate.
