Dissections
Sponge:
Sponge are the ideal habitats for marine animals because they are able to thrive in most environments and 99% of sponges live in marine water. Also, they are important in nutrient cycles and also lower the nitrogen levels in their environment during their filtering process. The lesser levels of nitrogen are beneficial for other organisms to live in and recycle food food for other organisms as well.
how do they get enough light to carry out photosynthesis and why is this adaptation important

Jellyfish:
Jellyfish, hydra, and sea anemone are part of the phylum Cnidaria. The two basic body plans in these phylum are known as a medusa form and a polyp form. The medusa is the sexually reproducing, motile form commonly know as the jellyfish. The polyp is usually asexual and reproduces by budding. Hydras and sea anemones are polyps.
Jellyfish have two true tissue layers, an outer epidermis and an inner gastrodermis. A noncellular matrix called the mesoglea lies between these layers and makes up most of the jellyfish. It serves as a storage site for nutrients and a site for gas exchange. The epidermis is made up of only one layer of cells. The gastrodermis lines an incomplete digestive system called the gastrovascular cavity. Food enters through the mouth of this digestive system, and waste exits through the mouth as well. The gastrodermis is also only one layer thick, but it is made of darker cells.
I also observed that jellyfish posses radial symmetry.

Squid:
Both squid and jellyfish are called "cepholopods". This word comes from cephalization, which is defined as "the concentration of sense organs, nervous control, etc., at the anterior end of the body, forming a head and brain, both during evolution and in the course of an embryo's development". Mollusks usually have four body parts: the foot, mantle, shell and visceral mass. A cephalopod is soft bodied and is a head attached to a foot divided into arms and tentacles. Squids use the siphon to feed, respirate, circulate, excrete, and breed. They also have a close circulatory system. Squids have specialized cells called chromatophores which allow the squids to change colors quickly. Squids also use jet propulsions to move around. They reproduce sexually by external fertilization.

Earthworm:
The earthworm is a long tube shaped organism with an anterior end and a posterior end. The earthworm's basic internal anatomy includes both male and female sexual organs, though the earthworm reproduces with an other earthworm than themselves. They also have a "heart" that regulates the two veins located inside the earthworm on top of the intestines. It also has a stomach for storing food and a gizzard to break the food down. There are a few similarities between an earthworm and a sponge, they are both multicellular but the similarities mostly end there. Squid, jellyfish, and earthworms are all segmented.

Grasshopper:
The grasshopper is segmented organism. It's divided into three sections: head, thorax, and abdomen. It's six legs are attached to its thorax. Grasshopper have compound eyes and have chemical receptors on their mouthparts for taste and smell. Grasshoppers have a pair of mandibles that is an adaption for feeding. Grasshopper have two legs adapted for jumping and two pairs of wings: a soft one and harder, protective one.

Perch:
The perch is part of the phyla Chordata. The perch has 4 different types of fins: pectoral, pelvic, dorsal, and caudal fins. The perch has all the basic organs: a heart and intestines as well as reproductive organs. Instead of lungs, the perch has gills. The perch has eyes and nostrils. The perch's body shows many adaptations for life underwater, like the swim bladder or its gills. Gills are a very efficient respiratory organ because of their ability to filter air out of water as it passes through them. The purpose of the swim bladder is allow the fish to control it's own density in order to enable it to rise up or sink down in water. The scales of the perch face away from the head of the perch. Because the scales all face the same direction, the fish can move from side to side without impediment. Also, the scales form a sort of shield layer to protect the perch. The lateral line of a perch is long line that stretches form the anterior to posterior end of the fish. Its function is to allow the perch to sense movement in the surrounding water.

Frog:
The frog is part of the phyla chordata. It is a vertebrae that lives both in water and land. The larvae of the frog are fishlike and live in the water using gills. The adults are terrestrial and respire using lungs and skin. Its moist skin contains mucous glandes. They don't have scaled or claws. Tadpoles are usually filter feeders or herbivores that feed on algae, eating nearly constantly. Their intestines are long and cold which helps break down plant material filled with food. Frogs are almost entirely carnivorous, eating nearly anything they can catch and swallow. They have long, sticky tongues that are specialized to catch insect. Food goes from the mouth into the esophagus into the stomach, and continues in the small intestine. Then it travels to the large intestine and exits through the cloaca. Through the cloaca, wastes, urine, and eggs or sperm exit the body. Their circulatory system forms a double loop. They reproduce sexually with internal fertilization. They have a well developed nervous and sensory system. Their legs are developed to help then make lengthy jumps.
