    The Cobia (Rachycentridae) and Remoras (Echeneidae) have been placed together under one initial group, mainly because the Cobia is the sole member of its family, but also because its closest relatives happen to be the Remora family

    Other good reasons for placing these two families together are, their similar appearance, similar habits and the overall lack of individual species in local waters.

  • Jacks, Jack Mackerels, Pompanos & Scad (Carangidae)

    A large and diverse family comprising various subfamilies found in local water. These include the Mackerels, Trevallies (Jacks), Scad Pompanos along with various other species.

    Most species are fast moving, predatory fish which can be found at both inshore reefs and deeper, offshore sites.

    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.

    Elasmobranchii is one of the two subclasses of cartilaginous fish in the class Chondrichthyes, the other being Holocephali (Chimaeras).

    The main features that set Elasmobranchs apart from the vast majority of other fish groups are the lack of a swim bladder, a cartilaginous skeleton and skin comprising tiny "tooth-like" structures called dermal denticles, rather than the typical scales found on most other fish species.

    Due to the relatively small number of species found in local waters, i decided to group the sharks, skates and rays together.

    I've also added the family group to all three categories (Reef, Pelagic and Benthic) as there are species which inhabit one particular zone but not the others eg. Stingrays are obviously Benthic whilst Whale Sharks are typically Pelagic..
