Sagenista

From Wikipedia, the free encyclopedia


Sagenista is a protist organism found in Costa Rica.

Sagenista belongs to the Protophyta category due to its plant like characteristics. It is only found in desolate regions of Costa Rica. It belongs to: Domain Eukaryota, Kingdom Chromista, Phylum Opalozoa, and Sub-Phylum Sagenista, generally described as slime nets and Bicoecids.

It has a special organelle called a Bothrosome. It is usually found in a marine environments rich in algae and sea grass. They are capable of movement by use of this organelle. They are generally decomposers.

Contents

[edit] Bothrosome

Capable of excreting an extoplasmic net of filaments for cells to glide upon. These tiny filaments provide a network for cells to travel upon to soak up nutrients from the surrounding environment.

[edit] Uses of Sagenista and Labyrinthulomycota

Are cultivated for their active production of Omega-3 fatty acids. These acids are used as an approved additive for animal feed.

[edit] Labyrinthula

Possesses a bothrosome, Is being studied for its pathogenic nature in marine environments. Has killed an entire species of Sea grass as well as some species such as a particular snail that relies on the grass.

[edit] Caecitellus

Roughly spyhrical, Only 2-7 meters in diameter, Has two flagellum, Glide on filaments produced by bothrosome, The two flagella provide a wrap around the organism to form a sort of exoskeleton,

[edit] Cafeteria

Planktonic species which has only been found in salt water. The two flagellum propel the cell. Reproduce asexually through binary division. Feed on bacteria and small Eukaryotes.

[edit] Other info

Until recently Sagenista was labeled as a Fungus. It produces Asexually and sexually through use of spores. There is a debate about whether some species of Sagenista contains a photosynthetic pigment labeled chlorophyll C.
