a Beroe ovata, b unidentified cydippid, c "Tortugas red" cydippid, d Bathocyroe fosteri, e Mnemiopsis leidyi, and f Ocyropsis sp. [17]. Among animal phyla, the ctenophores are more complex than sponges, about as complex as cnidarians (jellyfish, sea anemones, etc.), and less complex than bilaterians (which include almost all other animals).
The leopard bush fish (Ctenopoma acutirostre), also known as leopard bushfish, [2] spotted ctenopoma, [1] leopard ctenopoma, [3] spotted climbing perch, spotted leaf fish, spotted cichlid or spotted bushfish, is a freshwater fish. It is a member of the family Anabantidae, which is part of a group popularly known as labyrinth fish (gouramies and ...
The vast majority of ctenophores, including Callianira bialata, feed on zooplankton (small organisms carried by currents) and ichthyoplankton (fish eggs and larvae). They capture their prey using sticky cells on their tentacles called colloblasts. [citation needed] These organisms are hermaphroditic, meaning they possess both female and male ...
Unlike cnidarians, Mnemiopsis does not sting. Their body comprises 97% water. They have a maximum body length of roughly 7–12 centimetres (3–5 in) and a diameter of 2.5 centimetres (1 in). It is euryoecious, tolerating a wide range of salinity (2 to 38 psu), temperature (2–32 °C or 36–90 °F), and water quality.

It is believed to have been the main cause of decline in these waters after dissection confirmed its stomach contents had large quantities of the local fish eggs and larvae.
