Some branchiurans are able to withstand rapid changes of salinity and will also switch hosts from marine to non-marine species.

Some diversification has taken place, with the city now having an industrial base formed of marine, education, information communication and technology, food, tourism, creative, environment and sports industries.

Some orders of heterotardigrades are marine, others are terrestrial, but as for all tardigrades, all are aquatic in the sense that they must be surrounded by at least a film of moisture in order to be active-though they can survive in a dormant state if the habitat dries out.

Some species, called zooxanthellae, are endosymbionts of marine animals and play an important part in the biology of coral reefs.

Some studies suggested the haplosporids, mostly parasites of marine invertebrates, might belong here but they lack alveoli and are now placed among the Cercozoa.

Some polychaetes, marine annelid worms in the family Serpulidae, secrete a hard tube made of calcium carbonate, adhering to stones or other shells.

Some tags added religion, e. g., Công Giáo for Catholic

Some linguists do not differentiate between languages and dialects, i. e. languages are dialects and vice versa.

Some of them are not main-stream types, but most of them have received special attention ( e. g., in research ) due to end-user requirements.

Some of them are much simpler than full fledged DBMSs, with more elementary DBMS functionality ( e. g., not supporting multiple concurrent end-users on a same database ), with basic programming interfaces, and a relatively small " foot-print " ( not much code to run as in " regular " general-purpose databases ).

Some DBMSs cover more than one entry in these categories, e. g., supporting multiple query languages.

Some such units employ batteries that can provide power for several hours in case of external power interruption ( e. g., see the EMC Symmetrix ) and thus maintain the content of the volatile storage parts intact.

Some are deeper, e. g. 6m for the diving pit at Sheffield, England.

Some DBMSs cover more than one entry in these categories, e. g., supporting multiple query languages.

Some such units employ batteries that can provide power for several hours in case of external power interruption ( e. g., see the EMC Symmetrix ) and thus maintain the content of the volatile storage parts intact.

Some professional dominatrices are also " lifestyle " dominatrices-i. e., in addition to paid sessions with submissive clients they engage in unpaid recreational sessions or may incorporate power exchange within their own private lives and relationships.
