What's the difference between pelagic and thresher?
Pelagic
Definition:
(a.) Of or pertaining to the ocean; -- applied especially to animals that live at the surface of the ocean, away from the coast.
Example Sentences:

(2) The involvement of active inorganic ion transport and Na+,K(+)-ATPase in oocyte hydration in Atlantic croaker (Micropogonias undulatus) and spotted seatrout (Cynoscion nebulosus), marine teleosts which spawn pelagic eggs, was investigated by examining changes in the inorganic ion content of ovarian follicles containing mainly oocytes, by performing in vitro incubations of the follicles with ion channel blockers, and by assaying membrane preparations of ovaries containing hydrating and non-hydrating oocytes for Na+,K(+)-ATPase activity and content.

(5) Brown weasels and white animals undergoing the spring change to the brown pelage and reproductive activity molted, grew a new white coat, and became reproductively quiescent after treatment.

(7) It is concluded that the white muscle of the pelagic species studied is functionally and structurally adapted for sustained aerobic activity with relatively abundant mitochondria being preferentially situated close to the source of gas and metabolite exchange.
(8) Pelagic threshers grow to nearly four metres long, around two metres of which is tail.
(9) In contrast, all or most of the Merkel cells that normally develop within collars or annular clusters in the pad epidermis (around both the vibrissal and intervibrissal or pelage hairs) either disappeared within a few days or failed to develop.
(10) Metabolic and vascular adaptation of teleost lateral propulsive musculature to an active mode of life was investigated in four pelagic teleosts (mackerel, yellowtail scad, pilchard and Australian salmon).
(11) Appropriate seasonal patterns and levels of torpor, body weight, pelage color stage, and food intake were exhibited after T implant removal although serum T was clamped to long-day levels during the preparatory phase.
(12) It is suggested that the pineal gland product, melatonin, initiates changes in the central nervous system and endocrines which result in molting, growth of the white winter pelage, and reproductive quiescence in the weasel.
(13) Two trials were carried out to investigate the potential of small pelagic fish (Rastriobola argenteus) locally referred to as omena, as a protein supplement for pigs.
(14) A previously undescribed morphological variant (completely red) was observed in one specimen of the east bank, where pelage color of the local population varied from completely black to completely red.
(15) Fresh water fishes are generally macrosomatic and microptic, marine fishes (especially coral reef fishes) are microsmatic and macroptic while piscivorous pelagic fishes are macrosmatic and macroptic.
(16) We suggest that tissue from within the ethmoid region of the skull in pelagic fishes is the only site yet identified where magnetite suitable for use in magnetoreception is concentrated.
(17) Pelage hair follicles were isolated by gentle microdissection from 8-12-day-old rats, and maintained in supplemented Williams E medium.
(18) About 60% of fluorescing eggs placed in the pelage were recovered in collecting trays underneath the host in 2 h. An average of 87.7 eggs per cat was laid during the last 8 h of the scotophase compared with 49.9 and 59.1 eggs during the other 8-h periods.
(19) Digested mixtures of squid (Loligo reynaudi), Pelagic Goby (Sufflogobius bibarbatus) and Cape Anchovy (Engraulis capensis) did not resemble the undigested standards of each species respectively.
(20) In addition to acting as a chemosignal, the Harderian material serves two major homeostatic functions: (1) the lipids on the pelage act to insulate the animal against cold and wetness, and (2) the lipids and pigments darken the pelage and increase radiant absorption.
Thresher
Definition:
(n.) One who, or that which, thrashes grain; a thrashing machine.
(n.) A large and voracious shark (Alopias vulpes), remarkable for the great length of the upper lobe of its tail, with which it beats, or thrashes, its prey. It is found both upon the American and the European coasts. Called also fox shark, sea ape, sea fox, slasher, swingle-tail, and thrasher shark.
(n.) A name given to the brown thrush and other allied species. See Brown thrush.
(n.) Same as Thrasher.
Example Sentences:
(1) Pelagic threshers grow to nearly four metres long, around two metres of which is tail.
(2) Marine biologists had long suspected that threshers used their tails to help capture their prey.
(3) Captured on handheld cameras in waters 10 to 25 metres deep, the film is thought to be the first to show thresher sharks using their tails to hunt in the wild.
(4) Understanding how thresher sharks feed will help with efforts to protect them, Oliver said.
(5) Threshers are not the only marine predators to use tail-slaps.
(6) Suggestions included a giant squid, whose eyes can be as large as soccer balls, a bigeye thresher shark, which can reach can reach 16ft, a marlin or a particularly large sailfish.
(7) Among both sexes, threshers had a significantly higher attack rate than did nonthreshers.
(8) The hunt is on to find a buyer for the troubled company behind the off-licence chain Threshers after the formal appointment of KPMG as administrators tonight.
(9) Simon Oliver, a marine biologist at the Thresher Shark Research and Conservation Project in the Philippines, said the sharks' "tail slaps" reached a speed of 24 metres per second, or more than 50mph.
(10) Measurements of ventricular volumes suggest that the ventricles of the great white, Atlantic shortfin mako and common thresher sharks are better adapted to respond to demands for increases in cardiac output via increased heartbeat frequency in comparison with ectothermic species of shark.
(11) The group, which trades as Threshers, Wine Rack, Haddows and The Local on the high street, has 1,300 shops.
(12) We keep the eyeball of a bigeye thresher in a jar in the laboratory here and people walking by it get spooked by this large, dead blue eye staring at them.

(14) The sharks in the footage are "pelagic" or "open water" threshers, one of three species of thresher shark.
(15) Ventricle weights of the warm-bodied great white shark, Atlantic shortfin mako, and the common thresher shark (the latter presumed to be warm-bodied) are similar to those of ectothermic blue sharks, sandbar sharks, dusky sharks, tiger sharks and scalloped hammerhead sharks.
(16) It shows how thresher sharks accelerate towards dense shoals of fish, then brake by throwing their pectoral fins forward, causing the back end of the fish to rise in the water.
