A similar blue crab appeared in "Lion 3: Straight to Video". Rose Quartz recorded the crab with a video camera before Greg was ready to introduce himself to Steven. A bunch of blue crabs were seen in "Say Uncle" when Uncle Grandpa showed up in the beach.
They strongly resemble the Chesapeake Blue Crabs.
The "Butt Lobster" is a lobster that clings onto Pearl's posterior in "Steven and the Stevens", prompting Garnet to point out that she has a lobster on her butt.
The Crystal Gems warped back from the Sea Shrine and, as a result, the lobster came along with them, along with a fish, an octopus, and a crab. Pearl was not aware that the lobster was on her and was startled when Garnet pointed it out. Its current whereabouts are unknown.
It strongly resembles The Australian Lobster.
Cat Steven's Siblings
They were put up for adoption at the end of "Pool Hopping" with their current whereabouts being unknown.
The Dog appears in Steven's dream sequence in "Steven Floats". The dog is brown and short and has 3 teeth showing as well as its tongue sticking out. It bears a resemblance to a chihuahua.
In the dream Steven has, Steven is afraid that he will not get his donut. Steven imagined that Sadie fed his donut to the dog.
Mask Island Fish
There are at least two species of these fish inhabiting the island; a more common trout-like species, and a larger predatory species with sharp teeth similar to a barracuda. Similar to the rest of the creatures on Mask Island, these fish are magenta in color, and seem to bear a smiling expression, even after being speared by Sadie while she's fishing. However, after being cooked by Lars, these fish instead appear to have sad expressions on their faces.
Seagulls have appeared in various episodes including "Monster Buddies", "Watermelon Steven", "Sworn to the Sword", "Steven Floats", and "Bismuth". They look like typical seagulls, having white feathers and yellow beaks. They are often seen searching for food. Unlike many seagulls in real life, the seagulls that occur in Steven Universe are not afraid of the close presence of humans, and will only cower if threatened.
They strongly resemble American Herring Gulls.
It strongly resembles the Bluestripe Garter Snake.
Steven the Third
"Steven the Third" is one of Steven Jr's goat kids.
Steven the Third lives with its parents and one sibling at the Sky Spire. As Steven The Third was not seen when the Crystal Gems first visited the location in the episode "Giant Woman", but rather made its first (and so far only) appearance in "Warp Tour", its date of birth probably occurred some time between the two episodes.
It strongly resembles a Fainting Goat.
In the episode "On the Run", the Raccoon was seen traveling along with Steven and Amethyst. It is gray, with a black and white, striped tail. It has white eyes with black circles around them and white ears along with black fur on their outsides.
It strongly resembles the North American Raccoon.
Onion was originally going to feed the mouse to his pet snake, upsetting Steven. To make him feel better, Onion did not kill the mouse, and instead hid it in his mouth for the duration of the episode.
It strongly resembles the Common Field Mouse.
Onion's Snake is a pet that Onion currently owns. The snake made its debut in "Onion Friend". It lives in a darkened terrarium that sits on a dresser across the room from Onion's bed. It is unknown what the snake's name is.
It strongly resembles the Blue Python.
"Party Guy" is an unseen snake mentioned in "Gemcation". Residing at Cool Ranch, Pearl and Amethyst encounter Party Guy. Pearl starts screaming, and Amethyst informs Steven and Greg of the snake, referring to it as a 3-foot-long, hissing, reptilian "party guy".
Strawberry Battlefield Butterflies
The Strawberry Battlefield Butterflies are white and pink butterflies native to the Strawberry Battlefield, first seen in "Serious Steven". They get in Steven's eyes when he becomes covered in strawberries.
A duck is seen in "Lars and the Cool Kids", sitting on a log in Dead Man's Mouth. It is a brown duck with a green head and a white "collar". It flies off quickly when the Magic Moss swallows the log it is sitting on.
It strongly resembles the Mallard Duck.
They strongly resemble Terns.
Whales are seen in "Lion 2: The Movie". Their silhouettes are briefly shown underwater while Lion runs across the ocean.
Mask Island Worm
The Mask Island Worm was seen in the episode "Island Adventure". It is a dark purple worm with the same "mask" as the fish on the island. Steven and Sadie use it as bait to catch fish.
A frog is seen in "The Answer". It appears in Garnet's retelling of Ruby and Sapphire's story. The frog eats a butterfly that Sapphire is admiring, before being picked up by Ruby and shown to an excited Sapphire.
It is likely based off of the Arctic Hare, due to its location, though it lacks the black tips on its ears characteristic of the species.
Rose's Lions are a pack of lions that live in the desert, and were tamed by Rose Quartz. There are seven in total, 3 lions and 4 lionesses. They are first seen in "Buddy's Book," in a flashback where Buddy Buddwick encounters Rose in the desert. Among the pack is Lion.
Onion's Gang's Bugs
Onion's Gang's Bugs consists of several bugs, that were put into a race with each other. They consist of a grasshopper, a stinkbug, a pillbug, a caterpillar, a ladybug, and a stag beetle. A centipede was also seen coming out of Soup's hat/pot.
A rattlesnake briefly appears in "The Question". Ruby has a short standoff with it, before it slithers away.
It appears to be based on a Western diamondback rattlesnake.
Bluebirds are a nest of wild birds that appear in the episode "Little Homeschool". The babies are saved by Steven during his fight with Jasper. Later, the mother can be seen.
The River Fish appears in the episode "Fragments". It is caught by Steven during his training montage, and subsequently cooked and eaten.
It appears to be a species of trout.
