+ AMBI ecological groupAZTI’s Marine Biotic Index ecological group
+ Asexual reproductionReproduction which does not involve formation and fusion of gametes and results in progeny with an identical genetic constitution to the parent and to each other. Reproduction may occur by binary fission, budding, asexual spore formation or vegetative propagation. In asexual division in eukaryotic organisms, all cell divisions are by mitosis.424973

+ Body shapeThe general shape of the body of an organism.
+ Life stage(click on Life stage at the bottom of the page to expand)
+ Body sizeA measurement of the size of the organism. The measurement used to express body size varies within taxonomic groups. For example, some disciplines measure diameter, others carapace length, total body length or wing span. Also, body size can vary with gender and life stage.
+ Body size (qualitative)Trait that describes the size class of an organism.
+ GenderThe sex of an organism. The sum of all structural, functional and behavioural characteristics distingiusing males, females and hermaphrodites. (Lincoln et al., 1998). The sum characteristics, structures, features and functions by which a plant or animal is classed as male or female. In some animals sex is entirely genetically determined, in others the sex may change in response to environmental conditions. (Henderson's dictionary of biology; Lawrence, 2005)416344

+ Generation time1: The average duration of a life cycle between birth and reproduction. 2: The mean period of time between reproduction of the parent generation and reproduction of the first filial generation. (Lincoln et al., 1998). Period of time to complete a life cycle in the lab. (Definition composed by Line Le Gall, Olivier De Clerck, Sofie Vranken and Marine Robuchon, based on diverse literature sources, in the framework of compiling macroalgae traits.) 416344

+ Irradiance preference380501
+ Life cycleThe type of life cycle an organism has. Life cycle according to Lincoln et al., 1998: 1: The sequence of events from the origin as a zygote, to the death of an individual. 2: Those stages through which an organism passes between the production of gametes by one generation and the production of gametes by the next.416344

+ Modes of reproductionThis trait describes which mode of reproduction animals use to produce their young.
+ Paraphyletic groupA group of taxa derived from a single ancestral taxon, but one which does not contain all the descendants of the most recent common ancestor; a category based on the common possession of plesiomorphic characters (symplesiomorphy) (Lincoln et al., 1998).416344

+ Species exhibits underwater soniferous behaviour

Does the species actively1 or passively2 produce sound under natural conditions3 while submerged in water?

Definitions for terms used in the values of this trait:

1Active sound: produced deliberately in association with a particular behaviour or situation, frequently with specialized sonic organs or structures, and are generally used for communication; also referred to as intentional, deliberate, or specialized sounds (Looby et al., 2022).

2Passive sound: may not be associated with specialized sound-producing structures nor with specific behaviours or situations, though they may still serve some signal function; also referred to as incidental, unspecialized, or mechanical sounds (Looby et al., 2022).

3Natural conditions: in the absence of artificial manipulation, such as an electrical current or direct handling.

4Acoustic study or documentation: documentation in the peer-reviewed or grey scientific literature of the presence or absence of audible sounds through listening live or on a recording in captivity or the field (Looby et al., 2022).

5Morphological or physiological study or documentation: documentation in the peer-reviewed or grey scientific literature of the presence or absence of morphological and/or physiological structures with sound production functions (Looby et al., 2022).

6Ancestral state reconstruction analysis: the extrapolation back in time from measured characteristics of individuals to their common ancestors using statistical techniques to, in this case, recover information on the likelihood of soniferous behaviour (Joy et al., 2016; Rice et al., 2022).

7Artificial conditions: involving human intervention or manipulation, such as an electrical current or direct handling.

8Uncertainty: doubt or uncertainty expressed by researchers conducting examinations for sound production about their conclusions (e.g., that the species they examined was correctly identified, that they correctly identified active versus passive sounds; Looby et al., 2022).

9Validated: The researchers’ conclusions have no associated uncertainty in the documentation (see above).
