Furthermore, it is explained about the type / phylum kingdom animalia

Kingdom Animalia phylum

1. Phylum Porifera

Porifera comes from the word shaft and ferre. Shaft means a small hole. Meanwhile, ferre means to carry. So porifera is an animal that carries or has small holes in its body.

Porifera is the first multicellular metazoa. The characteristics possessed by porifera are as follows.

  • The body is multi-celled and has radial symmetrical properties
  • His body is hollow or porous
  • Living in water, sticking to a base
  • General body morphology resembles plants
  • Excretion and respiration are carried out by means of diffusion by the entire surface of the body.
  • Reproduction is done vegetatively by budding or budding and gemmule. While reproduction generatively by conjugation.

Porifera classification

  • Where the frame is a spicula formed from lime or CaCO 3. Spicules are monoaxone, triaxone, and tetraaxone. The examples are Clathrina, Lecosolenia, Schypa, Sycon, and Grantia.
  • Where the frame is a spicula formed by grit or silicate. Having a thorn with six branches or hexaxone. The examples are Aspergillum, Pheronema, Hyalonema, and Euplectella.
  • Where the frame is not spicules, but spongin fibers. Having thorns mixed with silicate monoaxone, triaxone, tetraaxone, and hexaxone. The examples are Euspongia, Hippospongia, and Spongilla.

The role of porifera in human life is as follows.

  • Sppons or demonospongiae can be used by humans for bathing and as a glass cleaner.

2. Phylum Coelenterata

Coelenterata comes from coelos and enteron. Coelos is a cavity. Meanwhile, enteron is the intestine. Thus, the coelenterata is an animal that has a cavity.

Coelenterata are sometimes medusae and polyps. The characteristics possessed by the coelenterata are as follows.

  • The body is radially symmetrical or cylindrical, globular, or spherical.
  • The diploblastic body wall consists of ectoderm and edoderm which have nettle or stinging cells.
  • Does not have anus, only has a mouth that is equipped with tentacles around it.
  • The digestive system is incomplete, only in the form of a gastrovascular cavity.
  • Do not have a respirator, circulation apparatus, or a special excretion tool.

Coelenterata classification can be explained as follows.

  • Hydrozoa class. Where this class is living solitary or colonizing. Its life cycle consists of the polyp and medusa phases. Gastrovascular cavity is not equipped with stomedeum and mesentrium, or nettle cells.

The mesoglea layer is a non-cellular layer which forms a paste. Gonadnya can be found in the epidermis layer. The examples of the Hydrozoa class are Hydra sp., Obelia sp., And Physalia pelagica.

  • Scyphozoa class. Where the body resembles a bowl. Its life cycle consists of the polyp and medusa phases. However, the media phase is more prominent. Examples from this class are Pericolpa Quadrigata, Lucernaria, and Aurelia aurita or jellyfish.
  • Anthozoa class. Where the shape resembles a flower. The media phase has been reduced so that there is only a polyp phase. The Google layer is cellular. Examples of this class are Metridium or sea anemone, Tubifora musica or distilled coral, Antipathes dichotoma, Gorgonia flegellum or sea fan, Arcophora sp., Meandrina sp., Fungia sp., Astrangia danae, and Renilla reniformis.

The role of co -enterata in human life is as follows.

  • Jellyfish can be used for jellyfish flour, then processed into cosmetic ingredients.
  • In Japan, jellyfish are used for food.
  • Atolls, coastal corals, and barrier reefs can protect the beach from abrasion and are a breeding and hiding place for fish.

The platyhelminthes classification can be described as follows.

  • Turkish class. Where the body is stick-shaped, the ciliated epidermis, has two eyes, has no suction device. It lives in clear fresh water, sea water or a damp place, and rarely as a parasite. Can regenerate by cutting the body and high regeneration power. The examples are Planaria sp., And Alaurina couposita.
  • Cestoda class. Where the body is flat like a ribbon, consisting of the head or skoleks and the body or strobila. Have a hook sucker. Each body segment or proglotid is an individual and has its own breeding tool. Cestoda has hemaphrodite properties. The examples are Taenia saginata, Taenia solium in human intestine, Choanotaenia infudibulum in chicken intestine, Echinococcus granulosus in dog intestine and Dipylidium latum which attacks humans.
  • Trematoda Class. Where the body is covered by cuticles, it does not have bilateral cilia and symmetries. The mouth has a suction device. Trematodes have hermaphrodite and parasitic properties. For example, Fasciola hepatica is a parasite in sheep’s liver, Fasciola gigantica is a parasite in cow’s liver, Chlonorchis sinensis is a parasite in humans, Polystomum sp., Octobothrium and Schistosoma japonicum.

The role of Platyhelminthes can be human life, which is as follows.

  • In general platyhelminthes is harmful, because it has parasitic properties in humans and animals, except planaria sp.
  • Planaria can be used as food for fish.

4. Phem Nemathelminthes

Nemathelminthes comes from the words nemathos and helminthes. Nemathos means yarn. Meanwhile, helminthes means worms. Thus, nemathelminthes is a worm in the form of a thread, has an intestine, and has no probosis.

  • Nematophora class. Where the body is shaped like a small round hair, also called a hair worm. The examples are nectonema sp and gordiust sp. is a parasite on arthropods.

The role of nemathelminthes in human life can be explained as follows.

  • Most nemathelminthes have parasitic properties both in humans and animals.
  • But there are also worms that have an important role in maintaining the balance of nature through food webs, such as ascaris lumbricoides and ascaris suillae.

5. Phylum Annelida

Annelida is derived from the words annulis and oidos. Annulus means a small bracelet or ring. Whereas oidos means form. Thus, annelids are worms whose bodies are jointed like rings or rings.

The characteristics possessed by annelida are as follows.

  • As an ocean cleaner, because echinoderms help in cleaning the ocean
  • Used as food, such as sea cucumbers or sea urchin eggs
  • Used as decoration
  • Echinoderms can also be harmful because they eat oysters or pearl oysters and coral animals so that many die

9. Phylum Chordata

Chordates are animals that have four anatomical structures that emerge during the embryonic period. These structures are the notokorda or temporary body strap or axis, perforated dorsal nerve cord, pharyngeal cleft, and muscular anal peg tail.
