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.

Rhinochimaera pacifica, commonly known as the Pacific spookfish, knifenose chimaera, narrownose chimaera, Pacific long-nosed chimaera, or Pinocchiofish, is a species of chimaera in the family Rhinochimaeridae. [2] It lives in various parts of the Pacific Ocean and can be characterized by its long snout.
Long-nosed chimaeras are found in temperate and tropical seas worldwide, from 200 to 2,000 m (660 to 6,560 ft) in depth. [4] In August 2020, a long-nosed chimaera was brought up from 460 fathoms (2,760 ft; 840 m) off the Grand Banks of Newfoundland. [5] They range from 60 to 140 cm (2.0 to 4.6 ft) in maximum total length, depending on species.
Ogcocephalus corniger is a demersal fish, [10] of which little is known of its biology. Batfishes are ambush predators and their prey typically compises small gastropods, bivalves, crustaceans, worms and the occasional small fish. The eggs and larvae are pelagic, the larvae undergo metamorphosis when they settle on the bottom. [1]
The rays of the second dorsal fin and the caudal fin are black and yellow striped like the color pattern along the lateral line. This fish can be characterized by a long, pointed snout that can be darker colored than the rest of its body and has been recorded to reach lengths of up to 11 cm.
Alepisaurus ferox, also known as the long snouted lancetfish, longnose lancetfish, or cannibal fish, is a species of lancetfish found in the ocean depths down to 1,830 m (6,000 ft). [ 3 ] [ 4 ] This species grows to 215 cm (85 in) in total length and a weight of 9 kg (20 lb).
Longnose gar have a typical lifespan of 15–20 years with a maximum reported age of 39. This long lifespan allows the female to sexually mature around 6 years old. Males mature sexually as early as 2 years of age. Longnose gar are sexually dimorphic; the females are larger than the males in body length, weight, and fin length.
F. longirostris has a compressed yellow body with a black triangular region on its head, and as the name implies, a long, silvery snout. Usually 10 or 11 dorsal spines, a black spot on the anal fin, and rows of small black spots on the breast are found. The fish grows to about 22 cm (8.7 in) in length.
