    Shark Anatomy (50693674756) The gill slits of a whale shark flaring as it expels water from its pharyngeal cavity. ... Lamellae in the gill slits are thin, membrane ...

  3. Lamella (surface anatomy) - Wikipedia

    en.wikipedia.org/wiki/Lamella_(surface_anatomy)

    Lamellae on a gecko's foot. In surface anatomy , a lamella is a thin plate-like structure, often one amongst many lamellae very close to one another, with open space between. Aside from respiratory organs, they appear in other biological roles including filter feeding and the traction surfaces of geckos .

  4. Gill - Wikipedia

    en.wikipedia.org/wiki/Gill

    The gills are composed of comb-like filaments, the gill lamellae, which help increase their surface area for oxygen exchange. [5] When a fish breathes, it draws in a mouthful of water at regular intervals. Then it draws the sides of its throat together, forcing the water through the gill openings, so it passes over the gills to the outside.

    Lamella (surface anatomy), a plate-like structure in an animal; Lamella of osteon, the concentric circles around the central Haversian canals; Lamella (cell biology): (i) part of a chloroplast (thin extension of thylakoid joining different grana) (ii) the leading edge of motile cells, containing the lamellipodia

    The megamouth shark is an extremely rare species of deepwater shark, and the smallest of the three filter-feeding sharks. Since its discovery in 1976, only a few megamouth sharks have been seen, with 55 specimens known to have been caught or sighted as of 2012, including three recordings on film.

  7. Cardabiodon - Wikipedia

    en.wikipedia.org/wiki/Cardabiodon

    The corpus calcareum and radial lamellae, the two outermost layers of a mackerel shark vertebra, which are associated with the relationship between length and weight, were thicker than those of other large predatory mackerel sharks, suggesting that Cardabiodon was significantly heavier and stockier, although no estimation of its weight has been ...

  8. Lamnidae - Wikipedia

    en.wikipedia.org/wiki/Lamnidae

    The Lamnidae are the family of mackerel sharks known as white sharks. [2] They are large, fast-swimming predatory fish found in oceans worldwide, though they prefer environments with colder water. The name of the family is formed from the Greek word lamna , which means "fish of prey", and was derived from the Greek legendary creature , the Lamia .

  9. Lamellar structure - Wikipedia

    en.wikipedia.org/wiki/Lamellar_structure

    Fine lamellae solve this problem by shortening the diffusion distance between phases, but their high surface energy makes them unstable and prone to break up when annealing allows diffusion to progress. A deeper eutectic or more rapid cooling will result in finer lamellae; as the size of an individual lamellum approaches zero, the system will ...
