The number of radial canals in hydrozoans varies from one species to the next, however individuals within the
Aequorea genus have many more than average (Ruppert
et al., 2004).
Aequorea sp. was observed to be blue in colour, allowing it to blend in well with the surrounding water. Forty tentacles were counted on
Aequorea sp., however, this cannot be used as a distinguishing feature due to the fact that it was not known whether it was a juvenile or an adult. It should also be noted that while
Aequorea sp. did indeed have nematocysts, they did not appear to have an effect on humans.
It was found that
Aequorea sp. was inside-out. This is a process known as jellyfish eversion syndrome and it is found to occur only in captivity (Freeman
et al., 2009). Due to its rather unusual orientation,
Aequorea sp. was observed to exhibit a very strange feeding behaviour. For further information, jump to:
