Temaki & Nigiri also are some intrested sushi's

Temaki (手巻)

"hand rolls") is a large cone-shaped piece of nori on the outside and the ingredients spilling out the wide end. A typical temaki is about ten centimeters (4 in) long, and is eaten with fingers because it is too awkward to pick it up with chopsticks. For optimal taste and texture, Temaki must be eaten quickly after being made because the nori cone soon absorbs moisture from the filling and loses its crispness and becomes somewhat difficult to bite.

Uramaki (裏巻)

 "inside-out rolls") is a medium-sized cylindrical piece, with two or more fillings. Uramaki differs from other makimono because the rice is on the outside and the nori inside. The filling is in the center surrounded by nori, then a layer of rice, and an outer coating of some other ingredients such as roe or toasted sesame seeds. It can be made with different fillings such as tuna, crab meat, avocado, mayonnaise, cucumber, carrots. Uramaki has not been so popular in Japan and most of makimono is not uramaki because it is easy to hold makimono with nori skin by fingers. However, since some Western people dislike the black impression of makimono with nori skin, uramaki has become more popular in Western countries than nori-skinned makimono.

 Narezushi

Narezushi (熟れ寿司)

 "matured sushi") is a traditional form of fermented sushi. Skinned and gutted fish are stuffed with salt, placed in a wooden barrel, doused with salt again, then weighed down with a heavy tsukemonoishi (pickling stone). As days pass, water seeps out and is removed. After six months this funazushi can be eaten, remaining edible for another six months or more.

Nigirizushi

Nigiri-zushi

Nigirizushi (握り寿司)

 "hand-formed sushi") consists of an oblong mound of sushi rice that the chef presses into a small rectangular box between the palms of the hands, usually with a bit of wasabi, and a topping (the neta) draped over it. Neta are typically fish such as salmon, tuna or other seafood. Certain toppings are typically bound to the rice with a thin strip of nori, most commonly octopus (tako), freshwater eel (unagi), sea eel (anago), squid (ika), and sweet egg (tamago). When ordered separately, nigiri is generally served in pairs. A sushi set (a sampler dish) may contain only one piece of each topping.

Gunkanmaki (軍艦巻)

"warship roll") is a special type of nigirizushi: an oval, hand-formed clump of sushi rice that has a strip of "nori" wrapped around its perimeter to form a vessel that is filled with some soft, loose or fine-chopped ingredient that requires the confinement of nori such as roe, natto, oysters, sea urchin, corn with mayonnaise, and quail eggs. Gunkan-maki was invented at the Ginza Kyubey restaurant in 1931; its invention significantly expanded the repertoire of soft toppings used in sushi.

Temarizushi (手まり寿司) "ball sushi") is a ball-shaped sushi made by pressing rice and fish into a ball-shaped form by hand using a plastic wrap. They are quite easy to make and thus a good starting point for beginners.
