Sicyases sanguineus is a species of amphibious marine clingfish in the family Gobiesocidae. It lives in the Southeast Pacific along the entire coast of Chile and southern Peru. [1] [2]
Locally, it is known as pejesapo (literally, toad-fish). It inhabits shallow waters, including the intertidal zone. It can often be seen on exposed rocks above water, where it is able to breathe via the branchial surfaces and the skin. As long as it is kept moist by the splash of the wave action, it can survive for up to three days on land. [2] [3] Together with Chorisochismus dentex of southern Africa, it is the largest species of clingfish at up to 30 cm (12 in) long. [3]
The fish is characteristic of vertical rock walls in the middle and upper rocky intertidal community along the exposed coasts of Pacific coast of South America, ranging from southern Peru to southern Chile. [4] Its niche is unique, with no known parallel development in other rocky intertidal communities. The most likely determinants of the distribution of Sicyases sanguineus are areas where vertical rocky shorelines encounter ocean swells and ample benthic prey. [2]
Sicyases sanguineus attaches by means of a large disc formed of the fused and highly modified pelvic fins, bearing small and flattened dermal papillae. [5] The combination of suction by disc and adhesion by papillae secure the clingfish to the rock. [6]
When young, S. sanguineus is gregarious and often congregates on walls. They are alert and can detect moving objects over distances from 10–15 m (33–49 ft). [2] However, adults are quiescent and cluster on exposed rocks often well above water level. [7] Among the many places where they can be seen are the boulder fields in Pozo Toyo and Antofagasta Bay, Chile. [2]
Sicyases sanguineus is omnivorous, feeding on a wide range of algae (brown, green and red) and many types of invertebrates (especially molluscs such as chitons, marine snails, limpets and mussels, and barnacles, but also crabs, isopods, amphipods, insect larvae and sea urchins). They only take relatively small animals. For example, they have been observed living in apparent peace with large chitons and limpets, whereas the small individuals are eaten by this clingfish. [2]
As known from some other clingfish, Sicyases sanguineus has relatively large, protruding front teeth on the upper jaw. The front teeth on the lower jaw are shorter and more chisel-like. When feeding on algae, they scrape the teeth along the rock surface, leaving distinctive marks. [2]
Other methods are used when feeding on molluscs like limpets. The most common way for the fish to connect itself to a flat smooth surface with its ventral sucker. It then repeatedly swings its head in a small arc, raking its teeth downward in strokes. [6] A second mode in which Sicyases sanguineus feed on them is to insert its teeth on the limpet's shell and then twist. This produces a characteristic break into the shell posteriorly and anteriorly. [6]
A tide pool or rock pool is a shallow pool of seawater that forms on the rocky intertidal shore. These pools typically range from a few inches to a few feet deep and a few feet across. Many of these pools exist as separate bodies of water only at low tide, as seawater gets trapped when the tide recedes. Tides are caused by the gravitational pull of the sun and moon. A tidal cycle is usually about 25 hours and consists of one or two high tides and two low tides.
The intertidal zone or foreshore is the area above water level at low tide and underwater at high tide; in other words, it is the part of the littoral zone within the tidal range. This area can include several types of habitats with various species of life, such as sea stars, sea urchins, and many species of coral with regional differences in biodiversity. Sometimes it is referred to as the littoral zone or seashore, although those can be defined as a wider region.
The Patellogastropoda, common name true limpets and historically called the Docoglossa, are members of a major phylogenetic group of marine gastropods, treated by experts either as a clade or as a taxonomic order.
Clingfishes are fishes of the family Gobiesocidae, the only family in the order Gobiesociformes. These fairly small to very small fishes are widespread in tropical and temperate regions, mostly near the coast, but a few species live in deeper seas or fresh water. Most species shelter in shallow reefs or seagrass beds, clinging to rocks, algae and seagrass leaves with their sucking disc, a structure on their chest.
Chiton glaucus, common name the green chiton or the blue green chiton, is a species of chiton, a marine polyplacophoran mollusk in the family Chitonidae, the typical chitons. It is the most common chiton species in New Zealand. Chiton glaucus is part of a very primitive group of mollusc with evidence of being present in up to 80 million years of the fossil record.
Loxechinus albus is an echinoderm of the family Parechinidae, native to coastal southern South America, ranging from Ecuador, along the entire coasts of Peru and Chile, to Argentina, as well as the Falkland Islands. It is the only species in the genus Loxechinus. It is known as the Chilean sea urchin or red sea urchin, but the latter name is typically used for the North Pacific Mesocentrotus franciscanus and it is not the only species of sea urchin in Chile. L. albus is found on rocky reefs and shores in the intertidal and subtidal zones to a depth of 340 m (1,120 ft).
Cellana exarata, common name the black-foot ʻopihi and Hawaiian blackfoot is a species of edible true limpet, a marine gastropod mollusc in the family Nacellidae, one of the families of true limpets. ‘Opihi are significant in Hawaiian history where they have had many uses such as food, tools, and jewelry. They are known as a "fish of death".
Seashore wildlife habitats exist from the Tropics to the Arctic and Antarctic. Seashores and beaches provide varied habitats in different parts of the world, and even within the same beach. Phytoplankton is at the bottom of some food chains, while zooplankton and other organisms eat phytoplankton. Kelp is also autotrophic and at the bottom of many food chains. Coastal areas are stressed through rapid changes, for example due to tides.
Lottia gigantea, common name the owl limpet, is a species of sea snail, a true limpet, a marine gastropod mollusc in the family Lottiidae. Its genome has been sequenced at the Joint Genome Institute.
Lottia digitalis, commonly known as the fingered limpet or ribbed limpet, is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Lottiidae. These limpets are usually found on the surface of rocks in the high intertidal region on the coastal fringes of the north-eastern Pacific Ocean.
Scutellastra longicosta, the long-spined limpet or the duck's foot limpet, is a species of true limpet, a marine gastropod mollusk in the family Patellidae, one of the families of true limpets. It is native to the coasts of South Africa where it is found on the foreshore. It cultivates a species of crustose brown algae in a "garden".
Lipophrys pholis, commonly known as shanny, also known as the smooth blenny or common blenny, is a species of combtooth blenny. It matures at two years of age. Distributed in the Eastern Atlantic from the southern Norway to Morocco and Madeira, including the Mediterranean and the Balearics. Lipophrys pholis feed primarily on crustaceans, but also feed on other invertebrates and plants.
Chorisochismus dentex, the rocksucker or giant clingfish, is a species of clingfish found along the coast of southern Africa from Namibia to northern Natal, South Africa. It inhabits the intertidal and subtidal zones in shallow reefs and rock pools. This species is the only known member of its genus.
Derilissus is a genus of clingfishes belonging to the family Gobiesocinae found in the western Atlantic Ocean. This family of fish is identified by their appearance as small fish with sucking discs which allow them to attach themselves to various surfaces. Derilissus differs from other genera due to its attached gill membranes.
Lepadogaster is a genus of clingfishes native to the eastern Atlantic Ocean extending into the Mediterranean Sea. Lepadogaster belongs to class Actinopterygii. This means that they share many of the same characteristics as eels, ray-finned fish, and sea horses to name a few. The main characteristic of all of them though is having fin rays. These fin rays are made of webbed skin and are attached to portions of the body that connect fins to the bones. Lepadogaster species have a distinct difference in the formation of their dorsal and anal fins. While most other ray-finned fish spines, branched fin-rays, and middle radials, Lepadogaster species do not have these. Instead, they have cartilage in place of the mentioned features. These clingfish are mainly found near the rocky coasts and inside intertidal zones. Lepadogaster is known mostly as a clingfish, meaning that it spends most of its time attached to the surface of rocks.
Plaxiphora albida, the white Plaxiphora chiton, is a species of chiton in the family Mopaliidae.
Spongites yendoi is a species of crustose red seaweed with a hard, calcareous skeleton in the family Corallinaceae. It is found on the lower shore as part of a diverse community in the southeastern Atlantic and the Indo-Pacific Oceans.
Diplecogaster bimaculata, the two-spotted clingfish, is a species of fish in the family Gobiesocidae found in Black Sea, Mediterranean Sea and Atlantic Ocean where it is found on rocks and among seagrass or shell beds.
Chirodactylus variegatus, the Peruvian morwong or bilagai, is a species of marine ray-finned fish traditionally regarded as belonging to the family Cheilodactylidae, the members of which are commonly known as morwongs. It is found in the southeastern Pacific Ocean off the western coast of South America.
Enoplochiton echinatus is a Southeast Pacific species of edible chiton, a marine polyplacophoran mollusc in the family Chitonidae, the typical chitons.
