Skulpins, also spelt as sculpins, belong to the superfamily Cottoidea which has 11 families with around 756 species of fish. Of these 11 families, Cottidae is the most elaborate with about 275 species in 70 genera.
The genus Cottus in this family of fish is the most popular one and these fish are often called by the name, freshwater sculpins. There are 68 recognized and separate species in this genus Cottus and we are going to study a few of the species of sculpins in it.
All sculpin species have a broad head. The mottled or the Beard's sculpin (Cottus bairdii) is a freshwater habitat species found throughout North America.
The slimy sculpin (Cottus cognatus) is also found in cold rocky streams and lakes across North America. The banded sculpin is seen in the southeastern and midwestern United States.
The identification of sculpins can be done by looking for a big head, wide fins, and tapering body. Some have mottled skin that ranges from light tan to dark brown in coloration.
Many species of sculpins are bottom-dwellers and are mostly found inactive at the bottom of marine habitats. Some are found in shallow sea waters and some live in deeper waters. The others left, mostly in the Cottus genus, are found in freshwater habitats.
Many sculpins are actually small, camouflaged fishes. All species are usually similar to each other. Identification can be done by a small range of minor differences in looks and the wildlife they inhabit.
All species are widely distributed across the world. Sculpin species are known to live in both ocean and freshwater zones like rivers and lakes.
The mottled sculpin food includes aquatic insects and organisms, mollusks, snails, other sculpins of the same kind, and trout. The diet consists of bottom-dwelling animals. Humans generally do not like eating sculpins, however there are cases of sculpins being on menus.

Skulpin Interesting Facts
What type of animal is a skulpin?
The sculpin is a fish species of the superfamily Cottoidea that is widely distributed across the world.
What class of animal does a skulpin belong to?
Sculpins belong to the class of Actinopterygii in the kingdom of Animalia.
How many skulpins are there in the world?
The population of sculpins in the world is not known. However, there are 756 species of sculpin fish known all over the world and there is no danger to the life of these fishes currently. They are often caught while fishing and many species of sculpins are also used as bait to catch other fishes like trout and salmon.
They are abundant in all freshwater rivers and lakes and marine habitats in the world.
Where does a skulpin live?
The sculpin fish species are known to be found all over the world. There are various different species found and all are categorized by habitual differences. The members of Cottidae are mostly seen in the northern regions of the world in streams and rivers.
The banded sculpin is found in 14 different states in the southeastern and midwestern United States. The sculpin fish is found in streams within the Mississippi River basin.
The mottled sculpin is found widespread in North America. These sculpins are most abundant in the Great Lakes region towards Hudson Bay and throughout eastern Canada and then south to northern Alabama and Mississippi.
The slimy sculpin is found throughout the northeastern United States and many parts of Canada.
What is a skulpin's habitat?
Sculpins are found in both marine habitats and freshwater habitats all over the world. They live at the bottom of the aquatic habitat with a rocky substrate. Deeper waters and shallow waters both are used.
Sculpins are known to prefer cool and clear streams with rocks at the bottom of a river or a lake. They can camouflage themselves very well in these rocky bottoms. It is easy to get confused between the rocks and the fish. The main distribution range is restricted to these habitats throughout history.
The mottled sculpin is found near gravel bottoms and sandy areas of small streams and small rivers. This fish is abundantly found throughout the Great Lakes.
The banded sculpin however is found in all freshwater areas from small streams to large upland rivers. Slimy sculpins prefer clear, cold, fast-moving water streams with gravel to cobble substrate. They are a bottom-dwelling species living under a cover.
As all sculpin fish inhabit areas with fast-moving water, their flattened body helps them save themselves from fast water currents among the rocks along the bottom. Sculpin fishes have small, closely spaced pelvic fins that help them to cling onto rocky areas.
Who do skulpins live with?
We do not know whether skulpins live alone or in groups.
How long does a skulpin live?
The average life span of a mottled sculpin is six years. The banded sculpin is known to live for four years.
How do they reproduce?
Male mottled sculpins defend the nest cavity in the spring season. Nest cavities as seen in history are below rocks and crevices. Males attract the females to the nest for spawning.
Females lay the eggs and the male species stays in the cavity until they hatch and the young leaves the nest. The average number of eggs while spawning is around 300-500 for most of the species. The eggs hatch in 17 days and young leave the nest in around 14 days.
Spawning in banded sculpins happens beneath rocks similar to the mottled sculpin. During the mating season of the slimy sculpin, males are dark on the backs and sides and they have an orange coloration on the first dorsal fin.
This orange coloration on the first dorsal fin is to show the females of their reproductive prowess. However, this is also a disadvantage for slimy sculpin males as predators can easily spot them with the orange dorsal fin.
All sculpins spawn in spring.
What is their conservation status?
The conservation status for the slimy, mottled, and beaded sculpin is Least Concern by the IUCN Red List. All other species of sculpin fishes are abundantly found all over the world and are currently not in danger. However, some are caught while fishing and some are also used as bait while fishing.
Skulpin Fun Facts
What do skulpins look like?
All sculpin species are characterized by a broad flattened head, scaleless bodies, and spiny dorsal and lateral fins.
The mottled sculpin (Cottus bairdii) as the name suggests has dark black-brown mottling all over its body. This pattern and spots are seen over the fin, sides, and the whole rear. The body is flattened like all other species.
Two dorsal fins are seen. The first one has black spots on the front and backside. A whitish belly is seen.
Large pectoral fins are seen on the banded sculpin. A rusty brown color is usually seen, however this brown changes according to the substrate. The slimy sculpin has free pelvic fins and has no scales. The first dorsal fin has seven to nine soft spines and the second has 16–18 fin rays.
How cute are they?
The broad head and flat shape of the body do not make this species cute.
How do they communicate?
Fishes communicate tactically and chemically.
How big is a skulpin?
The length of the mottled sculpin is around 2.99-4.02 in (7.5-10.2 cm). The length of the slimy sculpin is 2.48-3.58 in (6.3–9.1 cm). The length of the banded sculpin is up to 7.09 in (18 cm).
How fast can a skulpin swim?
They are not known to swim much due to the lack of swim bladders.
How much does a skulpin weigh?
The weight is not known for all the species. Adults of the slimy sculpin weigh up to 0.015 lb (6.8 g).
What are the male and female names of the species?
Males and females are not given different names.
What would you call a baby skulpin?
Baby skulpins do not have any special names.
What do they eat?
The slimy sculpin is known to have a diet of aquatic insects, crustaceans, fish eggs, trout eggs, and small fish. The fish is often hunted by brook trout, salmon, northern pike, and lake trout.
The mottled sculpin (Cottus bairdii) is known to have a diet of small fish, aquatic insect larvae, fish eggs, brook trout and brown trout eggs, and most crustaceans.
Are they poisonous?
Some sculpin species have spines on their fins that hold venomous poison. One prick from these spines can cause a terrible pain if you get pricked.
Would they make a good pet?
They are not considered pets because they thrive in the wildlife habitat.
Did you know...
Known predators of the banded sculpin (Cottus carolinae) include belted kingfishers, northern water snakes, and great blue herons.
Sculpin species have smooth pectoral fins on the upper edge. These pectoral fins are webbed with sharp rays along the lower edge. This phenomenon helps when gripping the substrate and anchor in fast-flowing water.
A sculpin fish does not have a swim bladder in the body as it always stays in a habitat at the bottom of the water. It generally does not need to swim.
Some sculpins are eaten in many parts of the world.
Do skulpins have teeth?
Yes, some sculpins are known to have teeth.
How did the skulpin get its name?
Sculpins are any fish that have wide, heavy heads. They are small fish in the family Cottidae.
