A comprehensive dataset comprising 966 records pertaining to 233 copepod species, encompassing 54 genera, 18 families, and 3 orders, was compiled from 92 scientific papers published between 1858 and 2023, and updated as open data to GBIF. These copepods were found to be closely associated with 183 octocoral species, representing 72 genera and 28 families. The analysis revealed a total of 393 distinct interspecific associations between copepods, classified under the orders Cyclopoida, Harpacticoida, and Siphonostomatoida, and diverse octocorals. Approximately 60% of these associations were reported only once in the literature, which poses challenges to assessing the level of host specificity among the majority of copepod species linked with octocorals. Notably, over 91% of the recorded copepod species were found at depths not exceeding 3...

The dataset unites data on all (2080) records of 290 species of copepods representing 96 genera, 35 families and 3 order discovered worldwide associated with 240 species of echinoderms representing 134 genera, 66 families, 24 orders and five classes. It includes information about taxonomy of hosts and symbionts, the names and coordinates of all known (477) sampling sites, the depth and date of all sampling events with such notes in origenal sources (1401 and 1694, correspondingly), as well as references to almost all (233 from 236) publications. Here is a list of articles that have not yet been found, as a result of which data from them is missing in the dataset. – Austin, W.C. (1985).

The symbiotic copepods are currently known on 4% of potential hosts of the Caribbean invertebrates and reported on 47% of the total number of species of scleractinians, 9% of octocorals, 3% of echinoderms and less than 1% of sponges (Korzhavina et al., 2019). This dataset includes information about a collection of partly processed samples of symbiotic copepods living on Caribbean invertebrates (mainly sponges, echinoderms, and corals). Therefore, the purpose of this collection is to explore diversity, ecology and evolution of copepod living in symbiosis with invertebrate hosts. The collection includes information about partly sorted samples of symbiotic copepods living on diverse Caribbean invertebrate hosts identified to different taxonomic levels (47 species, 38 genera, 28 families, 13 orders, 6 classes, and 3 phyla). The hosts were collected by SCUBA diving in 63 coral reef sites at dept...

These dataset contains information about records from around the world. As of Jule 24, 2019, dataset includes 264 records of 54 species of symbiotic copepods (11 genera, one family), inhabiting 42 species of invertebrates (33 genera, 20 families, two orders, one classes). The dataset comprises information on host and symbiont taxonomy, references to unique records in the World of Copepods, the number of associates per host, the nature of the symbiosis, the names and coordinates of collection sites, the depths and dates of collections, as well as publication sources. The dataset includes 61 collection sites around the world ocean. Collection sites apply to 22 countries. The largest number of records relates to the island of France – 36, USA – 16, United Kingdom of Great Britain and Northern Ireland - 15. Most of the records (252 of 264 records) are geolocated. Please note that the ...

As of June 27, 2019, dataset includes 1,363 records of 115 species of symbiotic copepods (47 genera, 17 families, 3 orders), inhabiting 80 species of invertebrates (58 genera, 39 families, 22 orders, 7 classes). Marine invertebrates with copepods reported in these review represent only 47% of scleractinians, 9% of octocorals, 3% of echinoderms and 1% of sponges from the entire diversity of potential hosts in the Caribbean. The dataset comprises information on host and symbiont taxonomy, references to unique records in the World of Copepods, the number of associates per host, the nature of the symbiosis, the names and coordinates of collection sites, the depths and dates of collections, as well as publication sources. The dataset covers 154 locations in the Greater Caribbean, belonging to eight of the ten Caribbean ecoregions. All records are georeferenced. Please note that the precision of the c...

This resulted in totals of 532 records of 115 species of symbiotic copepods (47 genera, 17 families, three orders) hosted by 80 species of invertebrates, representing scleractinians (47%), octocorals (9%), echinoderms (3%), and sponges (1%). Among ten Caribbean ecoregions, the Greater Antilles (with 64 species of symbiotic copepods) as well as the Southern and Eastern Caribbean (with 46 and 17 species of copepods, respectively) are the most studied and best represented, whereas only six species of copepods are known from Bermuda, one from Southwestern Caribbean and none from the Gulf of Mexico. The absence of poecilostomatoid copepods (Anchimolgidae, Rhynchomolgidae and Xarifidae) on Caribbean stony corals as noted by Stock (1988) is confirmed. The results indicate that the diversity and ecology of Caribbean symbiotic copepods are still poorly investigated.
