A Lot of Info about the Hound Needlefish
Tylosurus crocodilus crocodilus
This is one of the most widespread of the needlefishes, occurring in all three major oceans- often well offshore, including around remote island groups. This species is one of the largest of the group, growing to at least 1.5 metres in length, sometimes cited up to 2 metres. I has a relatively stout, cylindrical body and a shorter head compared with other needlefishes.
This species has been implicated in injuries and even deaths caused by startled fish leaping from the surface at night and accidentally impaling people travelling in open boats. As with other needlefishes, the hound needlefish is quite edible, but their greenish coloured bones tend to dissuade fussy eaters.

A Lot of Info about the Snake Mackerel
This information is taken from "Fishes of the Open Ocean" by Julian Pepperell.
Gemplyus serpens
The snake mackerel gives its name to the family, Gempylidae. It is an elongated, sinuous fish with well set back dorsal and anal fins and a series of finlets in front of a broad, forked tail. At the other end, it has a long snout and a large mouth equipped with very large, sharp teeth. Fishes with these features which include barracuda and needlefish, are "hover predators" - meaning that when they detect prey, they remain motionless before making a sudden forward lunge to grab the prey in their, long, toothed jaws.
This is probably the most widespread of the gempylids. It occurs globally in tropical, subtropical and, less frequently temperate waters. In contrast to many of the gempylids, which are benthopelagic, the snake mackerel is often found in the surface layers of the world's oceans and is a common bycatch of oceanic longline fisheries. Catches of intermittent, single fish on a longline suggest that this is a solitary hunter.
The snake mackerel grows to a length of about 1.2 metres.

A Lot of Info About the Unicron Leatherjacket
This information is taken from "Fishes of the Open Ocean" by Julian Pepperell
Aluterus monoceros
The leatherjackets and filefishes, members of the large family Monacanthidae, are nearly all inshore or estuarine fishes. However, some, including the unicorn leatherjacket, have entered the pelagic environment via their habit of associating with floating objects such as logs and kelp.
Presumably as a result of this life-style, this is one of very few species of leatherjacket that has a global distribution. It is found on both sides of all three major oceans, and around a number of oceanic islands. Juveniles often associate with jellyfish, while adults commonly associate with floating weeds, algae and debris.
The unicorn leatherjacket can be identified by its upturned mouth and its dull gray to brown color covered on the dorsal surface by numerous small brown spots.
This is a relatively large monocanthid, growing to about 75cm and a weight of at least 2kg.
