|
a) This is a slide of a sponge
b) ALL sponges are suspension feeders, meaning that their cells beat in a coordinated way to produce a water current that flows through small pores in the outer body wall, into chambers inside the body and out through a single layer opening. c) ADULT SPONGES ARE SESSILE but may produce larvae that swim w/the aid of flagella d) they have asexual reproduction, meaning fragments fall off and are able to produce a new individual e) some form radial symmetric tubes, in addition some like this one has branched spicules |
a) Identify this slide
b) how do they feed c) how do they move around d) how do they reproduce e) what is is shape or any extra additive features |
|
|
a) this is a sponge w/an asconoid body structure
b) in all sponge types, the body is designed to facilitate feeding. Water is pulled into the pores and canlas by the beating of the choanocytes flagella. It moves into the spongocoel and is eventually forced out through the osculum. As the water passes across the choanocytes, food particles (microscopic algae, bacteria, and organic debris) adhere to the cells and are eventually taken into food vacuoles for intracellular digestion. c) movements is limitted, they are sessile d) asexual reproduction occurs e) the opening is the OSCULUM, the many little lines are the SPICULES, the dark cells inside are OSTICA |

b) how do they feed c) how do they move around d) how do they reproduce e) what is is shape or any extra additive features |
|
|
This is a sponge w/an Ascon body type (Asconoid body structure) and the opening here is the Osculum, which is formed by little small spicules
|

|
|
|
This is a sponge w/an syconoid body structure. in the middle open space is SPONGOCOEL, open areas leading into or out of the sponge is called INCURRENT CANAL, closed sections w/in the sponge are called the RADIAL CANAL, little small circular cells are called CHOANOCYTES, inside the inner ring a cave-like section is called an APOPYLE, a small opening leading into a radial canal can be called an OSTIUM, longer cells on the inside are called PINACOCYTES, darker areas on the outside of the sponge is an area of darker cells called the MESOPHYL. The cell on the inside is a Amphiblastula larvae, which is a product of sexual reproduction.

|
This are tentacles from a HYDRA, a common fresh water hydrazoan.
Id. Class: Phylum Cnidaria |
Identify the slide?
|
|
|
This is an Anterior end of a hydra.
Located are Tenticles, on teh tenticles are Cnidocytes, the top of the hydra is the Hyptostome and the mouth. It is from the Phylum Cnidaria class. |
Identify the slide?
|
|
|
This is an Hydras mid section, the darker area is either the Testis or the Ovary, depending on the location of the lump. Testis are closest to the tentacles, and toward the end is the "BASAL DISC", which would be more closely directed to the Ovary.

This is a transverse cross section of a female hydra.
The outermost part is the EPIDERMIS, then the GASTRODERMIS, little cells w/in the gastrodermis are MESOGLEA, and the center is the COELENTERON. |

|
This is a from the class Scyphozoa, it is a common moon jelly called Aurelia.
This is a fertilized egg, the PLANULA, that may be retained on the oval armof the medusa |
Identify the slide?
|
|
|
This is close visual of an Aurelia's gastric pouch, the GONAD. W/in each GONAD there are gastric filaments.
These four gonads are branched together w/radial canals. Located on the outside is called circular canals that continue around the perimeter of the body. |

|
|
|
this is a moon jelly, Aurelia, from the Class Scyphozoa.
This jelly is known as the scyphistoma, which is the planula larvae metamorphose into a feeding polyp. The Aurelia is similar to the hydra, just that is possesses many more tentacles. The scyphistoma feeds and grows for awhile, then transforms into a reproductive polyp called a strobila |
Identify the slide?
|
|
|
This is an Aurelia scyphistoma. This is the developing stage in the life cycle of the jellyfish.
|
Identify the slide?
|
|
|
This is a Aurelia Strobila. ONLY under favorable condition do the scyphistoma develop into a strobila. It consists of many upside down little medusa's that are popped off rythmically when ready. These new medusa are called EPHYRAE.
|

|
|
|
This is a Aurelia Strobila. It has newly developed medusa's developing one on top of another. They are rythmically popped off when ready. The new medusa are called Ephyra.
|
Identify the slide?
|
|
|
this is a Aurelia ephyra larva, which gradually develops into adult jellyfish, it has located on the outer arms sensory organs called RHOPALIA and located in four areas around the center is the GONADS
