Needlefish (family Belonidae) or long toms [2] are piscivorous fishes primarily associated with very shallow marine habitats or the surface of the open sea. Some genera include species found in marine, brackish, and freshwater environments (e.g., Strongylura), while a few genera are confined to freshwater rivers and streams, including Belonion, Potamorrhaphis, and Xenentodon.

Kyphosus sectatrix, the Bermuda chub, Pacific drummer, beaked chub, grey drummer, Pacific chub or white chub, is a species of marine ray-finned fish, a sea chub from the family Kyphosidae. This species is found in tropical and subtropical coastal waters worldwide.
The seven native fish species regularly seen in fresh water are the flagtail (Kuhlia xenura), the mullet (Mugil cephalus), the gobies (Awaous stamineus, Lentipes concolor, Sicyopterus stimpsoni and Stenogobius hawaiiensis), and the sleeper goby (Eleotris sandwicensis).
Keeltail needlefish are found in the western Atlantic Ocean between North Carolina and Brazil, including the Gulf of Mexico, the Bahamas, and the Caribbean Sea. [6] In the Indian Ocean, they are known off of East Africa, with their range continuing into the Pacific, reaching the Hawaiian Islands and continuing north to the Ogasawara Islands. [7]
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups. Ambiguous common names are accompanied by their possible meanings. Scientific names for individual species and higher taxa are included in parentheses.
It is a benthic species, feeding on or near the seabed. Its diet includes crabs, shrimps, molluscs, sea urchins, starfish, brittle stars, sea cucumbers, tunicates and seagrasses. [2] The spotted trunkfish, like all trunkfish of the genus Lactophrys, secretes a colourless toxin from glands on its skin when touched. The toxin is only dangerous ...
While the houndfish has no spines, its dorsal fin has 21–25 soft rays, and its anal fin has 19–22. [2] They are also known to have 80–86 vertebrae. [2] A key way of distinguishing the houndfish from other members of the genus Tylosurus is that the houndfish's teeth point anteriorly when the fish is a juvenile.
These aggregations may also include other species such as the sleek unicorn surgeonfish, Naso hexacanthus. Oceanic triggerfish are currently thought to move as a group, migrating together from the open ocean to shallower waters for nesting purposes, and returning together to the open ocean once nesting is complete.
