Globigerina bulloides is a species of heterotrophicplanktonicforaminifer with a wide distribution in the photic zone of the world's oceans. It is able to tolerate a range of sea surface temperatures, salinities and water densities, and is most abundant at high southern latitudes (up to 40° S), certain high northern latitudes (up to 80° N), and in low-latitude upwelling regions. The density or presence of G. bulloides may change as a function of phytoplankton bloom successions,[1] and they are known to be most abundant during winter and spring months.[2]
At one point in the 19th century, researchers of the life-histories of this genus came to the firm conclusion that these animals lived and died in the ooze in which they were found, many hundreds of feet below sea level.[5][6] This has now proved to have been an incorrect assumption,[when?] despite the thoroughness of those investigations.
