The Atlantic needlefish (Strongylura marina) is a common demersal needlefish species common in marinas and other areas with minimal currents. Body very elongated, rounded; extremely elongated jaws form a long beak, with numerous needle-like teeth; rear of the top jaw-bone by being exposed when the mouth is closed. It has no gill rakers, the fins without spines; low lobes at the front of the dorsal and anal fins. Its dorsal fin is composed of 14–17 rays, anal fins is composed of 16–20 rays, and pectorals 10–12. [3] Atlantic needlefish are found from Maine to Brazil and have been known to venture into fresh water for short periods, water columns, estuary, and reef associated. [3]

Geographic range

S. marina is found along western Atlantic coastal waters from Maine to southern Brazil, including areas along the coast of the Gulf of Mexico and Caribbean. [4] [5] Atlantic needlefish are not restricted to ocean waters; they can be found in various estuaries and are capable of ascending well upstream into fresh water. S. marina is found in shallow waters throughout the Chesapeake Bay [6] there depth max is 5ft [3] . In Texas, S. marina is known to inhabit these drainage units: Sabine Lake (including minor coastal drainages west to Galveston Bay), Galveston Bay (including minor coastal drainages west to mouth of Brazos River), Brazos River, Colorado River, San Antonio Bay (including minor coastal drainages west of mouth of Colorado River to the mouth of Nueces River), and Nueces River. [7] S. marina has also been introduced and now inhabits parts of the Tennessee River drainage throughout Alabama and Tennessee. [8]

Ecology

As juveniles, the diet of S. marina consists of 70% shrimp, mysids, and amphipods and 30% fish, while adults are exclusively piscivorous. [9]

The predators of S. marina include larger piscivorous fish such as the Atlantic tarpon (Megalops atlanticus). [10] Less common predators include the common bottlenose dolphin (Tursiops truncatus) and juvenile lemon sharks (Negaprion brevirostris). [11] Since they are surface swimmers, Atlantic needlefish are also preyed upon by some birds. The competitors of S. marina include similar-sized piscivorous fish species such as bonefish. Although the maximum salinity S. marina can tolerate is 36.9 ppt, [10] they are able to adapt to a wide range of salinities, regularly venturing into fresh water. [5]

Diet

The Atlantic Needlefish eat a variety of things based on their body composition. Their diest can range from feeding on shrimp, small fish such as killifishes and silversides. Besides shrimp, small fish, they eat various zooplankton, ranging from zoobenthos to nekton.Their ability to eat is to patiently stalk their prey then goes into the attack by tilting its long pointed mouth sideways into its scissor-like jaw. [12]

Swimming behavior

Anguilliform locomotion is widespread among various aquatic animals and it represents a convergent strategy for being able to move through the water. Elongated fishes in various phylogenetic and ecological disparate families exhibit undulatory locomotion. The Atlantic Needlefish elongated teleost is related to the flying fishes that reside in the surface of water of coastal marine environments. Needlefishes possess a posterior arrangement of dorsal, anal, and caudal fins. The Atlantic Needlefish is a unique anguilliform swimmer that possesses through it prominent fins, which lives in coastal surface-waters, and can be able to propel itself across the surfaces of water to be able to escape predation. There has been no kinematic studies to date that has described the axial kinematics of anguilliform locomotion. Additionally, there has not been any data on the fin kinematics of anguilliform in swimming fishes, despite the fact the median fins may have some contribution substantially to the lateral body profile. [13]

Life history

Spawning typically occurs in late spring and summer. Spawning mostly inshore bays and estuaries. Evidence has suggested that they spawn in river mouths. [12] In Texas, near ripe females have been reported in February. [10] This species is believed to be an iteroparous springtime spawner which mature roughly at the age of 2. The Atlantic Needlefish lays demersal, transparent eggs 3.5-3.6 mm in diameter with chorionic filaments that protrude from the eggs being made. The filaments allow the eggs to remain within tangled mass that attach to submerged plants or other surfaces. [12] Females lay eggs that have many long, filamentous tendrils which attach to floating vegetation or other submerged objects and organisms. S. marina reaches reproductive maturity two years after being hatched. Spawning activity occurs in shallow, inshore habitats with submerged algal masses. [4]

S. marina depends on submerged vegetation for breeding and shelter. In the Gulf of Mexico, the eggs of S. marina attach to sargassum seaweed.

Conservation

S. marina is not currently considered to be a threatened species. It is not of high commercial importance, but a fishery exists for it and it is sometimes taken as bycatch. Sport fishermen take it by angling and seining, and then use it as bait. [1] Located is Golfo Dulce, Costa Rica, the Atlantic Needlefish spend majority of their time offshore. However, few days before the full moon, large schools of the Atlantic Needlefish gather at particular beaches around the gulf to spawn. [14] This event tends to occur in a specific time during the lunar cycle, and it only occurs in a few locations. This event has been occurring for a long time, and for generations, local families have taken advantage of the opportunity to fish, which has been now a tradition that is now limited to preserve local needlefish populations. [15]

Danger To humans

The Atlantic needlefish are predatory schooling fish with an elongated slender jaw that have been known to leap out of the surfaces of water at incredible fast speeds. There have been multiple documents of instances that the Atlantic Needlefish has caused injuries to humans, and the injuries can be more severe that their external appearances would indicate. There have been few cases of penetration of head or neck trauma that has been caused by the fish. However, the report which caused injury to the human is reported to cause partial spinal cord injury, which was caused by the Needlefish. Which has led to beneficial aspects, such as neurosurgical intervention and antibiotic prophylaxis. [16]

The bowfin is a bony fish, native to North America. Common names include mudfish, mud pike, dogfish, grindle, grinnel, swamp trout, and choupique. It is regarded as a relict, being one of only two surviving species of the Halecomorphi, a group of fish that first appeared during the Early Triassic, around 250 million years ago. The bowfin is often considered a "living fossil" because they have retained some morphological characteristics of their early ancestors. It is one of two species in the genus Amia, along with Amia ocellicauda, the eyespot bowfin. The closest living relatives of bowfins are gars, with the two groups being united in the clade Holostei.

<span class="mw-page-title-main">Needlefish</span> Family of fishes

Needlefish or long toms 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, while a few genera are confined to freshwater rivers and streams, including Belonion, Potamorrhaphis, and Xenentodon. Needlefish closely resemble North American freshwater gars in being elongated and having long, narrow jaws filled with sharp teeth, and some species of needlefishes are referred to as gars or garfish despite being only distantly related to the true gars. In fact, the name "garfish" was originally used for the needlefish Belone belone in Europe and only later applied to the North American fishes by European settlers during the 18th century.

<i>Strongylura</i> Genus of fishes

Strongylura is a genus of needlefishes from the family Belonidae which is distributed throughout the tropical and warmer temperate waters of the world, including some species which live in freshwater.

<i>Tylosurus</i> Genus of fishes

Tylosurus is a genus of needlefish, one of ten in the family Belonidae. They are found worldwide in tropical and warmer temperate seas and two species have been recorded as Lessepsian migrants in the eastern Mediterranean Sea.

The short-beaked garfish is an uncommon species of needlefish in marine waters of the eastern Atlantic Ocean. This pelagic needlefish is present off the coasts of Ireland, Spain, Portugal, and the United Kingdom, and possibly in the Mediterranean Sea, as well. This species was thought to be the same as the garfish because they share the same waters. The short-beaked garfish matures at 30 cm (12 in) and can grow to a maximum of 65 cm (26 in) while Belone belone can be 95 cm (38 in). Like all needlefish, this one has an elongated body with beak-like jaws that are lined with razor sharp teeth. The short-beaked garfish's lower jaw is longer than the upper. Its body is silvery like most needlefish and has a black stripe running across its lateral line. The dorsal and anal fins are very close to the caudal peduncle. These fish are oviparous. Eggs may be found attached to objects in the water by tendrils on the egg's surface. These spherical eggs are dispersed on the sea floor (demersal). Not much is known about this fish's feeding habits. It likely preys on small oceangoing fish. It has been caught using mackerel. Needlefish tend to be surface fish, so are preyed upon like Atlantic mackerel, European pilchard, sand smelt, etc. The specific name honours Anatolii Nikolaevich Svetovidov (1903–1985) who was an ichthyologist at the Zoological Institute in Saint Petersburg, Russia and a colleague of N.V. Parin.

<i>Tylosurus choram</i> Species of fish

Tylosurus choram, the Red Sea houndfish, is a species of needlefish from the family Belonidae. A marine fish bluish in color with a long slender body, and a pointed long toothed beak, found in most temperate, warm seas, and sometimes rivers, it is found in abundance in the Red Sea. It is a fast predator swimming in small schools near the water surface. Like other species of needlefish this species is oviparous, laying eggs which attach themselves to objects in the water by means of filaments which cover the outer layer of the egg. Tylosurus choram is found in the Red Sea and in coastal waters around the Arabian Peninsula to the Gulf of Oman. It has been reported twice, forty years apart, in the Mediterranean Sea off Israel. This species was described as Belone choram by Eduard Rüppell in 1837 with the type locality given as the Red Sea, the specific name choram is Arabic for needlefish.

<i>Eugerres plumieri</i> Species of ray-finned fish

Eugerres plumieri, commonly referred to as the striped mojarra or mojarra rayada, is a demersal fish from the Gerridae family. The family Gerridae is nicknamed the silverbodies because many of the species, this species included, have a silver-sheen to their bodies. This fish is often confused with other species from the Gerridae family such as the Irish Mojarra. It has been grouped in the order Perciformes due to its resembles of perch-like fishes. This species was discovered by French naturalist and zoologist, Georges Cuvier. It can be found in most areas of the Western Atlantic, excluding the Bahamas and West Indies.  

The long tom or freshwater longtom is a species of euryhaline needlefish native to Northern Australia and Papua New Guinea.: This species occurs in the coastal rivers of tropical Australia and New Guinea. In Australia it has been recorded from the Fitzroy River in Western Australia to the Dawson River in Queensland. It is found in areas of still or flowing water in larger rivers from the tidal reaches to far inland and adults are infrequently recorded in coastal marine waters. Preferred habitats include river channels, floodplain lagoons, muddy creeks and billabongs where it often shelters below overhanging vegetation or among submerged roots. It is a nocturnal hunter of small fishes, crustaceans and insects with the adults being almost exclusively piscivorous, ambushing their prey from cover. Strongylura krefftii was described as Belone krefftii by Albert Günther in 1866 with the type locality given as "Australia ". The specific name honours the Australian zoologist Gerard Krefft (1830-1881) who presented Günther with the type.

Strongylura strongylura, the spottail needlefish or blackspot longtom, is a species of needlefish from the family Belonidae. It is found in the Indian and western Pacific Oceans from the Persian Gulf east to Australia and the Philippines. This species occurs in coastal waters and in mangrove-lined lagoons as well as being recorded in estuarine areas and it has even entered freshwater. Living S. strongylura have been found alive and buried in mud during low tide. It is piscivorous, feeding mainly on clupeoids. This species is oviparous and the eggs adhere to objects in the water which catch the tendrils which cover the surface of the egg. Strongylura strongylura under the synonym of Strongylura caudimaculata is the type species of the genus Strongylura. It as originally described as Belone strongylura by Johan Coenraad van Hasselt in 1823 with the type locality given as Vizagapatam, India.
