Acestrorhynchus falcatus is a species of fish in the family Acestrorhynchidae.[2] It was described by Marcus Elieser Bloch in 1794, originally under the genus Salmo.[1] It inhabits the Orinoco and Amazon Rivers in the regions of Suriname, Guyana, and French Guiana. It reaches a maximum total length of 30 cm (12 in), and a maximum weight of 255 g (9.0 oz).[2]
Two shell valves that are not equal adhere to one another along the edges to form the ellipsoidal spore body. Each valve has a lengthy tail that is 20.5m in length. On its entire length, a uniform sheath encircled the tail. Three to four spirals of the arctic thread are contained in the 1.2 m polar capsules. A tightly adhering, uniform structural coating covered every surface of the immature and mature spores; it was predominantly thicker at the tails. Piscinoodinium pillulare was the major parasite for A. falcatus.
Acestrorhynchus falcatus feeds on finfish.[3] It is of minor interest to commercial fisheries.[2]
