Tag: Jellyfish & Salps - Gelatinous Zooplankton

In the Gulf of Thailand we encounter various species of free-swimming "jellies" belonging to a variety of families.

Although not all are related, they often have a similar appearance and are therefore mistaken for each other.

For this reason, I have created two separate galleries which contains members or the phylum Cnidaria in order to distinguish species more easily by physical appearance, rather than their biological relationship.

Although Salp (Salpidae) are NOT related to the either Jellyfish or Comb Jellies, they are often mistaken as such due to their similar appearances. It is due to this physical similarity that they are sometimes grouped together under the term

"Gelatinous Zooplankton"

.

For this reason, this gallery will contain the "medusozoa" Jellyfish from the phylum Cnidaria, the Comb Jellies of the phylum Ctenophora and the Salps of the family Salpidae.

The other members of the phylum Cnidaria that are physically dissimilar, such as the Corals and Anemones will be grouped within a separate gallery.

The species shown in this photograph belongs within the Carybdeidae family which is distinguished by the presence of four retractable tentacles, with one attached to a muscular base at each corner of the body.
