  • cavity
  • Bluefin tunas are obligate ram ventilators: they drive water into the buccal cavity through their mouth, then over the gills, while swimming. (wikipedia.org)
  • Our model took into account the transfer of heat between the portions of the myotomes comprising red muscle fibers adjacent to the spinal column and served by vascular counter current heat exchanges (henceforth referred to as `red muscle') and the water, as well as between the red muscle and the temperature sensor of the archival tags in the visceral cavity. (biologists.org)
  • Our model successfully predicted the recorded visceral cavity temperatures during vertical excursions provided that the rate constants for heat transfer between the ambient water and the red muscle during cooling ( k low ) and those during heating ( k high ) were very dissimilar. (biologists.org)
  • In this host, once infected oligochaetes, which serve as the first intermediate host, are ingested, Eustrongylides migrates through the intestine and is frequently encountered within the musculature, free within the body cavity, or encapsulated on the viscera. (biomedcentral.com)
  • relatively

  • Labyrinth fish (such as gouramis and bettas) have a labyrinth organ above the gills that performs this function. (wikipedia.org)
  • Fish are the gill-bearing aquatic craniate animals that lack limbs with digits. (wikipedia.org)
  • Ram ventilation is said to be obligatory in southern bluefin tunas, because the buccal-opercular pump system used by other teleost fish became incapable of producing a stream of ventilation vigorous enough for their needs. (wikipedia.org)
  • They are: The tuna is a sleek and streamlined fish, adapted for speed. (wikipedia.org)
  • Tuna have hearts that are much larger than other fish, they are about 10 times as large, relative to the size of the body. (sea-ex.com)
  • The declining production does not what so ever represent the depletion of neritic tuna fish stocks. (docplayer.net)
  • organisms
  • Tunas have highly specialized gills, with a surface area 7-9 times larger than that of other aquatic environment organisms. (wikipedia.org)
  • We seek to determine how different environmental factors, notably temperature and the threat of desiccation, affect organisms, and how organisms respond adaptively to these perturbations. (stanford.edu)
  • A primary focus of these studies is to determine how changes in environmental temperature affect the latitudinal and depth distribution patterns of marine organisms. (stanford.edu)
  • large
  • If such aspiration becomes successful, Thailand will be able to reduce its dependency on importing of a large quantity of tunas around the world and is capable of providing raw material to its tuna canning industry. (docplayer.net)
