The ninespine stickleback is a euryhaline and eurythermal species of teleost fish, occupying both freshwater and marine habitats in higher latitudes of the world. Recently, this species has been under great examination due to pond populations' adaptations of morphology, life history, and behavior which separates them from their marine ...
Fishes are a paraphyletic group and for this reason, the class Pisces seen in older reference works is no longer used in formal taxonomy.Traditional classification divides fish into three extant classes (Agnatha, Chondrichthyes, and Osteichthyes), and with extinct forms sometimes classified within those groups, sometimes as their own classes: [1]
The feeding habits of filefish vary among the species, with some eating only algae and seagrass; others also eat small benthic invertebrates, such as tunicates, gorgonians, and hydrozoans; and some species eat corals (corallivores). It is the latter two habits which have largely precluded the introduction of filefish into the aquarium hobby.
Artist representation of A. scriptus. Aluterus scriptus is a medium size fish which can grow up to 110 cm (3.6 ft) in length. [3] The body shape looks like an elongated oval, strongly compressed.
Fishes of the World is a standard reference for the systematics of fishes.It was first written in 1976 by the American ichthyologist Joseph S. Nelson (1937–2011). Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science.
The phylogenetic classification of bony fishes is a phylogenetic classification of bony fishes and is based on phylogenies inferred using molecular and genomic data for nearly 2000 fishes. [ 1 ] [ 2 ] [ 3 ] The first version was published in 2013 and resolved 66 orders. [ 2 ]
The three-spined stickleback appears to be a rather old species that has remained morphologically unchanged for more than 10 million years. The oldest record of the species is from the Alta Mira Shale of the Monterey Formation of California, which preserves an articulated skeleton that appears essentially identical to the modern G. aculeatus ...
FishBase is a global species database of fish species (specifically finfish). [1] It is the largest and most extensively accessed online database on adult finfish on the web. [2] Over time it has "evolved into a dynamic and versatile ecological tool" that is widely cited in scholarly publications. [3] [4] [5]
