Marine vertebrates. Flashcards
Salmon and trout belong to this order. Both types of fish have their pelvic (ventral) fins located far back on the body. They also possess a forked tail. All members of this order are born in freshwater. They then migrate to the ocean, where they spend most of their lives. They return to their freshwater nurseries only to spawn.
Salmoniformes.
The order comprises eels. They have characteristically long, slender bodies. They lack pelvic (ventral) fins and most do not have pectoral (breast) fins.
Anguilliformes
The order includes herrings, sardines, and anchovies. Most fish in this order are smaller than 12 inches in length. Most fish in this group display an important behavioral characteristic called schooling. The fish swim together in groups, which may include up to a million or more individuals and appear to behave as one large organism as they move.
Clupeiformes
The well-known codfish belongs to this order. A common feature of fish in this order is that the pectoral fin is positioned behind the pelvic fin. The fins of these fish are also spineless.
Gadiformes
Tuna and mackerel are examples of this order. It’s the largest order of fish with diverse characteristics. However, a common characteristic is that all representatives resemble the body structure of the perch fish—thin and oval shaped, tapered at the front and back. Most have the leading ray on the dorsal and anal fin modified into a spine.
