MOLLUCS


Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and in anatomical structure, but also in behaviour and in habitat. The phylum is typically divided into 9 or 10 taxonomic classes, of which two are entirely extinct.

 Cephalopod molluscs, such as  cuttlefish and octopus, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species. The gastropods   are by far the most numerous molluscs in terms of classified species, and account for 80% of the total.

TIPOS DE ANIMALES

HERBIVOURS   ANIMALS .    A  herbivore  is an at  animal   adapted to eating   plant material ,  for example foliage for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding.Horses   and other herbivores have wide flat teeth   that are adapted to grinding  grass trek bark and other tough plant material. A large percentage of  herbivores   have mutualistic  gut flora   that help them digest   plant matter , which is more difficult to digest than animal prey. This flora is made up of  cellulose - digesting  protozoans   or  bac teria .

OMNI VORS    ANIM ALS.                                                 Omnivore is a consumption classification for animals that have the capability to obtain chemical energy and nutrients from materials originating from plant and animal origin. Often, omnivores also have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet as well. Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities.  For instance, dogs evolved from primarily carnivorous organisms  while pigs evolved from primarily herbivorous organisms . What this means is that physical characteristics are often not reliable indicators of whether an animal has the ability to obtain    and nutrients from both plant and animal m atter.     WORDS THAT YOU DON´T UNDERSTAND : COMSUMPTION:CONSUMO

ARTHROPODS They constitute the moust numerous and diverse edge of the animal kingdom,it includes invertebrate animals endowed with an external skeleton and articulated appendages; among others ,insects,arachnids,crustaceans,etc... There are more than 1.200.000 described species mostly insects, representing at least 80%  of all knonw animal species,severals groups of arthropods are perfectly adapted to live in the air,just like vertebrates amniotes ,unlike all other phyla of animals,which are       aquatic or requier humid enviroments.It´s anatomy physiology and behavior reveal a simple but admirably effective design.
