<tabber>
|-|Sponges=The following is a list of '''sponges'''.
==[[Sponge]]s==
{{Link|SpongeBob SquarePants}} and his [[SquarePants family|family]] are sea sponges. In real life, sea sponges cannot walk or swim on their own, so they eat by [[:wikipedia:filter-feeding|filter-feeding]] (straining the surrounding water for nutrient particles). Many sea sponges reproduce by "[[:wikipedia:budding|budding]]," which is when a portion of the sponge breaks off and becomes a complete animal.

In ''[[SpongeBob SquarePants (musical)|The SpongeBob Musical]]'', SpongeBob's exact species name is identified: ''[[:wikipedia:Aplysina fistularis|Aplysina fistularis]]'', a yellow sea sponge commonly found in open waters.

The character was named "Squidward" instead of "Octoward" because the second name "just didn't work," according to [[Rodger Bumpass]].{{Citation needed}}

The [[Tentacles family]] and most of the other cephalopods are octopuses. Other octopuses who appear are {{Link|Squilliam}}, [[Squilvia]], and some of the members of the [[Cephalopod Lodge (location)|Cephalopod Lodge]]. Different species of octopuses make occasional appearances, such as a [[mom octopus]] and her children from "[[Sailor Mouth]]," an [[octopus vendor]] from "[[Walking Small]]," and a dancer from "[[Slimy Dancing]]." The only species allowed in [[Tentacle Acres]] are octopuses.
