Morphology: Scale type Scales have evolved over time and are of major importance in classifying fishes. Cyprinids like these prefer riffles and rapids--shallow, fast-flowing water. 1. flat or depressiform They normally live on the bottom of the sea floor flap their fins up and down to swim through the water in the same way a bird flaps its wings. See Table 4.4 for additional descriptions of fish body shapes. Anguilliform means eel-like (Fig. Distant from the most anterior point of the body to the deepest, Greatest vertical depth of the body. Other fish with this body type include pikes, gars, topminnows, killifish, needlefish, and barracuda. o Many bony fishes become sexually mature between one and five years.

Our study examines the evolution of characiform body shape in the context of shifts among different trophic ecologies and against the backdrop of independent evolution on two continents to reconstruct the history of the radiation and infer the relative influence of determinism versus contingency. Diversity in Gender o The vast majority of fish are dioecious meaning that there are male and female genders in separate bodies o Hermaphrodism, is the alternative to dioecism o Species can be either hermaphroditic simultaneously or sequentially o If simultaneous then they are both genders at the same time o If sequentially then the species changes genders due to environmental cues o Species that are born male are called protandrous o Species that are born female are called Protogynous, Modes of Sexual Reproduction o There are three primary ways that fish reproduce o Ovopartity lay undeveloped eggs, external fertilization (90% of bony fish), internal fertilization (some sharks and rays) o Ovovivparity internal development without direct maternal nourishment advanced at birth (most sharks & rays) Larval birth (some scorpeaniforme rockfish) o Viviparity Internal development direct nourishment from mother fully advanced at birth (some sharks, surf perches).

MOSQUITO FISH KILLIFISH, BOTTOM FEEDING FISHES Swim bladder absent or greatly reduced Most body shapes flattened dorsoventrally Bottom fish exhibit several types of feeding behaviors: bottom rovers bottom clingers bottom hiders flatfish deep bodied eel like rattails, Laterally compressed Deep bodied Dorsal and anal fins are relatively long Pectoral fins high on the body Pelvic fins moved forward Some have ventral keel DEEP BODIED FISH, Snake-like form Blunt or rounded heads Small or absent pectoral fins Dorsal and anal fins may be elongated SADDLED SNAKE EEL EUROPEAN EEL, Fish scales are dermally derived Vary greatly on bony fishes Can be armor like to no scales at all Bony plates slow movers Protection Weight issues, Also called dermal denticals Common in sharks GANOID SCALES, Bichirs, Bowfin, gars, sturgeons Usually rhomboid in shape CYCLOID AND CTENOID SCALES, Found in majority of bony fishes (Teleostei) Anterior usually overlapped by posterior of scale in front Gives fish more flexibility than fish with ganoid or cosmoid scales As a fish with cycloid or ctenoid scales grows, its scales also grow results in a pattern of concentric growth rings on the scale, Are often round flat and thin CTENOID SCALES, Often found on spiny fish Similar to cycloid except for tiny projections, Fins Other Structures Skeletal System Muscular System Locomotion, Varied and many forms Aid in locomotion, stability Generally located high up on sides of deep bodied fish which rely on precise movement to pick up food from bottom or in water column In rover predators these fins tend to be more toward or below the midline In slower moving rover predators or fish needing more surface area for stablility fins tend to be more rounded, Generally long on rover predators and deep bodied fish to provide stability while swimming Modified for swimming, reproduction (mosquitofish) May be continuous in eel like fish, Fleshy dorsal found in Salmonidae, smelts (Osmeridae), lanternfish (Myctophidae), catfish and CHARACINS Small size and lack of rays make it a mystery fin May be important post-larval when other fins poorly developed, tail fins Size and shape is dependent upon ecology and lifestyle, Developed independently in several groups Spines are effective, lightweight means of protection Increase the effective size of a fish May be poisonous (scorpionfish), MOUTH STRUCUTRES Reveals much about fish and its habit Position, shape size all related to what fish do Bottom feeding fish have downward pointing mouth inferior Surface oriented fish have upward on superior pointing mouth Most fish however fall into the category of terminal mouth that is location at end of snout Size and shape of mouth usually reflects shape of preferred food organism, are covered in most bony fish by thin flexible bony structure called the operculum little variability but size varies (bigger on active fish; smaller on less active fish), Vertebral column Skull Appendicular skeleton VERTEBRAL COLUMN - The vertebral column of fishes ranges in complexity from the very primitive notochord found in hagfishes, the cartilaginous vertebral column of the Chondrichthyes to the totally ossified vertebrae of the Osteichthyes The vertebral column provides fish with the basic structural basis for swimming and there is generally one vertebra per body segment, Compared with the vertebral column, the skulls of fishes are much more variable Functions of the Skull: Entry point for food Entry point for water needed in respiration Site of major sensory organs A protective structure for the brain, gills, eyes, etc. Ex: eel6.

Globiform globe-like These fish do not usually move quickly and depend on spines and/or toxins for protection. Eel-like fish include taeniform, anguilliform, and filiform shapes all in one category. o In general, species of a small maximum size begin reproducing at a younger age than those that have a large maximum size. These shapes represent miscellaneous fish. Globiform "Globe-like. " Blue Gill Body Shape Compressiform shape like that of angelfish looks thin when viewed from the front. Species with this Tag Distance between the highest. Su kirliligi genel olarak okyanuslar, denizler, nehirler, goller ve yeralti sulari gibi su kaynaklari uzerinde dogal ve insan faaliyetleri sonucu olusmus bir tur kirlilik olarak adlandirilabilir. C. This tail has a non-differentiated caudal fin. depressiformfish. Bottom fish is a very broad category that includes bottom rovers like catfishes, suckers, and sturgeons, bottom clingers like sculpins, bottom hiders like darters and blennies, and depressiform body types, like flatfish.
