    en.wikipedia.org/wiki/Loricifera

    Loricifera (from Latin, lorica, corselet (armour) + ferre, to bear) is a phylum of very small to microscopic marine cycloneuralian sediment-dwelling animals with 43 described species. [3] and approximately 100 more that have been collected and not yet described. [4] Their sizes range from 100 μm to ca. 1 mm. [5]

  3. Pseudoruminant - Wikipedia

    en.wikipedia.org/wiki/Pseudoruminant

    Pseudoruminant is a classification of animals based on their digestive tract differing from the ruminants. Hippopotami and camels are ungulate mammals with a three-chambered stomach (ruminants have a four-chambered stomach) while equids ( horses , asses , zebras ) and rhinoceroses are monogastric herbivores.

  4. Ruminant - Wikipedia

    Digestive system of ruminants [ edit ] Hofmann and Stewart divided ruminants into three major categories based on their feed type and feeding habits: concentrate selectors, intermediate types, and grass/roughage eaters, with the assumption that feeding habits in ruminants cause morphological differences in their digestive systems, including ...

    These are subdivided into two groups based on the relative size of various digestive organs in relationship to the rest of the system: colonic fermenters tend to be larger species such as horses and rhinos, and cecal fermenters are smaller animals such as rabbits and rodents. [4]

  7. Rotifer - Wikipedia

    en.wikipedia.org/wiki/Rotifer

    Rotifers have a small cerebral ganglion, effectively its brain, located just above the mastax, from which a number of nerves extend throughout the body. The number of nerves varies among species, although the nervous system usually has a simple layout. [17] The nervous system comprises about 25% of the roughly 1,000 cells in a rotifer. [18]

  8. Ungulate - Wikipedia

    Nevertheless, artiodactyls were far from dominant at that time: the perissodactyls were much more successful and far more numerous. Artiodactyls survived in niche roles, usually occupying marginal habitats, and it is presumably at that time that they developed their complex digestive systems, which allowed them to survive on lower-grade food ...

  9. Insect physiology - Wikipedia

    en.wikipedia.org/wiki/Insect_physiology

    An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
