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.

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

The exact salinity range if known (psu), else salinity zone(s) according to the Venice system:
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]
6. Polymixohaline [18-30psu]
7. Euhaline [30-40psu]
8. Hypersaline [>40psu]

Sociability

Colonial. Descriptive of organisms produced asexually which remain associated with each other; in many animals, retaining tissue contact with other polyps or zooids as a result of incomplete budding.

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

Valid synonyms of a species (not all of them).

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:
Resistant resting stages (cysts) are formed during periods of nutrient stress which fall to the bottom sediments and may later germinate to establish a planktonic population when conditions are suitable. These cysts are highly resistant to physical and chemical attack, are long-lived (>10 years) under suitably anoxic conditions, and are therefore capable of long-distance (inter-continental) dispersal by a number of natural or anthropogenic vectors.
From combination of confirmed planktonic and benthic resting cyst reports, G. catenatum has now been documented within discrete areas along the coastlines of all continents

Comments:
The primary form of population growth is through mitotic binary division of planktonic cells. Cell division occurs typically along a dorso-ventral diagonal plane, with the right side daughter cell migrating to a position below the other daughter cell and remaining attached to form chains. Other forms of division (sexual and non-sexual) have been noted in laboratory cultures.
The sexual lifecycle of G. catenatum is typical of most dinoflagellates. Haploid vegetative cells are induced to act as gametes by as yet unknown mating factors produced by other sexually compatible cells. Gametes can be induced (or promoted) in laboratory cultures under nutrient limited conditions; however, some level of sexual reproduction is often evident even under nutrient-replete conditions.
Developmental trait (?) Resting stages
