Clinocottus analis is a species of fish in the family Cottidae, one of the families of sculpins. It is known commonly as the woolly sculpin in English and the charrasco lanudo in Spanish.[1] It is native to the eastern Pacific Ocean, where it occurs along the coastline of California and Baja California.[1]
Description
This fish reaches up to 18 centimeters in length.[1] Their characteristic elongated and speckled body ends with a large wide and flattened head.[2] Their eyes are found on the top of their head perpendicular to their large mouth aligned with many teeth.[2] They are scaleless, instead, they have gills covering their large spine ending in a pair of sharp spines.[2] They have dorsal, anal and caudal fins, each with 12 to 15 rays.[2] The caudal fin is rounded and darker than the rest of their body.[2]

Ecology and metabolism
This species lives on the seabed of intertidal waters up to 18 meters deep.[1] It is commonly found in tide pools amidst algaes, but it leaves the tide pool area at will.[1] It can breathe air and has been known to survive out of water for up to 24 hours.[3]
Habitat
They are commonly found near the sand, small rocks and bedrock, specially in intertidal areas at near 19 m.[2] They are found in water temperature ranges between 6ºC and 22ºC.[2] They are able to survive rapid temperature fluctuations and rapid changes in salinity.[2]
Predators
In the United States is depredated by the greaat blue heron (Ardea herodias), Leucophoyx thula i Catoptrophorus semipalmatus[4]
Feeding
The diet of this species includes mainly crustaceans, especially amphipods, as well as fish eggs and larvae, polychaetes, and molluscs.[2] Most of its food items are light-colored or clear, suggesting that these are easiest for the fish to see against the dark background of its habitat.[5]
Reproduction
Their reproduction is oviparous with internal fertilization and spawning occurs in shallow coastal waters. Each female lays several batches of 50 to 1,300 eggs multiple times per year.[2] These have a size ranging between 12 to 25 mm, settling the larvae in the tide-pools. In a few months, they mature to a length of 50-60 mm in total.[6]
Behavior
They are non-migratory species.[2] They can camouflage themselves due to their subtle changes in body color.[2] Their mottled specks are green, greenish-black, greenish-brown and reddish covering their body as well as their fins.[2] The fins are also colored according to their body color patterned with light thin bands.[2]
Supplementary information
They are harmless to humans.[7]
The population dynamics of Clinocottus analis is highly seasonal. In general, growth and fertility peak from early spring to summer. However, survival is not seasonal.[6]
This fish has green blood plasma, the color caused by biliverdin tightly bound in protein complexes.[2]
