larvae were equally prevalent in spring (May) and late summer (September) samples.
This middle-sized scombrid
is restricted on the continental shelves of tropical and subtropical regions of the Pacific Ocean.
This species is an elongate scombrid
and the posterior end of the maxilla is concealed under the pre-orbital bone.
If so, this would indicate quite a slow growth rate for a Scombrid
The Pacific bluefin tuna (Thunnus orientalis) is a large pelagic scombrid
fish distributed widely in temperate parts of the northern Pacific Ocean (Collette and Smith, 1981).
The most abundant genera of medium-sized fish belong to the scombrid
family (Scombridae), the mackerel (Scomber) and the Spanish mackerel (Scomberomorus), or to the carangid family (Carangidae), such as the saurel (Trachurus) and jacks or kingfish (Seriola).
Endothermy has evolved in birds and mammals, or their ancestors, as well as in some reptiles (e.g., brooding pythons, large sea turtles, and maybe dinosaurs), scombrid
fishes (e.g., tunas and billfishes), lamnid sharks, insects, angiosperms (families Annonaceae, Araceae, Cyclanthaceae, and Palmae), and cycads (Hutchison et al.
Size, seasonal abundance, and length-weight relation of some scombrid
fishes from southeast Florida.
Finlets, which are small non-retractable fins located on the body margins between the second dorsal and anal fins and the caudal fin of scombrid
fishes, have been hypothesized to improve swimming performance.
Wahoo (Acanthocybium solandri) is a pelagic scombrid
with a tropical and subtropical distribution in oceanic waters worldwide (Collette and Nauen, 1983).
