Attidops cinctipes
A minute jumping spider in the family Salticidae, measuring 2–3 mm at maturity. The species name refers to its banded legs. It occurs in the United States and Mexico around the Gulf of Mexico, where it inhabits trees and woody surfaces. Its coloration provides camouflage against bark.

Doryodes latistriga
Doryodes latistriga is a moth in the family Erebidae described from specimens collected in coastal habitats of the northern Gulf of Mexico. It inhabits tidal creeks and salt marshes from Alabama to Louisiana. The species exhibits seasonal variation in wing coloration, with lighter spring and summer forms and darker fall and winter forms. Adults are active year-round.

Gammarus mucronatus
scud
Gammarus mucronatus is a small amphipod crustacean first described in 1818. It is a dominant species in salt marsh and estuarine habitats along the North American Atlantic coast and Gulf of Mexico. The species is multivoltine, producing multiple broods per season with overlapping cohorts. It serves as an important food source for fish and other predators while contributing significantly to energy flow and nutrient cycling in coastal ecosystems.

Habroscelimorpha dorsalis venusta
Gulf Beach Tiger Beetle
Habroscelimorpha dorsalis venusta, commonly known as the Gulf Beach Tiger Beetle, is a subspecies of tiger beetle in the family Carabidae (subfamily Cicindelinae). It is one of several subspecies within the Habroscelimorpha dorsalis species complex. Tiger beetles in this genus are typically associated with sandy coastal habitats. The specific epithet 'venusta' suggests an attractive or elegant appearance, consistent with the often colorful and patterned nature of tiger beetles in this group.

Haustoriidae
Haustoriidae is a family of amphipod crustaceans characterized by stout, robust bodies adapted for burrowing in sandy sediments. They are dominant members of intertidal and shallow subtidal sandy beach communities along the Atlantic coast of North America, with some species extending into the Gulf of Mexico and Pacific coast. The family radiated during the Eocene, with the Pacific-endemic genus Eohaustorius representing the most basal lineage, diverging approximately 31 million years ago. Haustoriidae are distinguished from other amphipod families by their specialized morphology for sand-burrowing and their limited dispersal capabilities, which have resulted in strong population structure and cryptic diversity across their range.

Lysmata
cleaner shrimp, peppermint shrimp
Lysmata is a genus of marine caridean shrimp distinguished by its unique sexual system of protandric simultaneous hermaphroditism. The genus includes two main ecological groups: cleaner shrimp that live in pairs and remove parasites from fish, and peppermint shrimp that often live in aggregations and consume pest anemones. All studied species begin life as males before maturing into functional simultaneous hermaphrodites capable of both producing and fertilizing eggs. Members of this genus are heavily targeted by the ornamental aquarium trade, with some species commanding high prices.

Minuca longisignalis
longwave gulf fiddler, Gulf Marsh Fiddler Crab
Minuca longisignalis, formerly Uca longisignalis, is a fiddler crab endemic to Gulf of Mexico salt marshes. It exhibits striking reproductive seasonality characteristic of warm-temperate lineages, with ovigerous females appearing no earlier than April and peak ovigery in June. The species constructs burrows in vegetated marsh areas, with burrow density and depth varying by elevation and distance from shoreline. It co-occurs with congeners such as Uca spinicarpa, though shows substrate preferences for different clay compositions.

Palaemon vulgaris
Marsh Grass Shrimp, Common American Prawn, Common Grass Shrimp, Marsh Shrimp
Palaemon vulgaris is a small, transparent caridean shrimp native to the western Atlantic Ocean. Adults reach less than 5 cm in length and display distinctive orange pigmentation on the eyestalks. The species has been studied for its specialized swimming mechanics, employing metachronal beating of pleopods and drag-reducing mechanisms during locomotion. It occupies coastal and estuarine habitats from Cape Cod Bay to the Gulf of Mexico.

Petrolisthes armatus
Green Porcelain Crab
Petrolisthes armatus, commonly known as the green porcelain crab, is a small porcellanid crab native to the southwestern Atlantic, particularly Brazil. The species has established invasive populations along the southeastern United States coast, where densities can exceed 30,000 individuals per square meter. Genetic studies confirm it as a single monophyletic species with exceptional geographic range spanning the Atlantic and eastern Pacific. It is frequently parasitized by the bopyrid isopod Aporobopyrus curtatus, which causes parasitic castration.

Pinnixa chaetopterana
tube pea crab
Pinnixa chaetopterana is a small, soft-bodied pea crab that lives symbiotically within the tubes of polychaete worms, primarily Chaetopterus variopedatus. It is a facultative commensal, occasionally free-living or associating with alternative hosts such as Amphitrite ornata. The species exhibits strong host fidelity and can distinguish conspecifics from heterospecifics. It ranges from Massachusetts to Uruguay along the western Atlantic, including Brazil and the Gulf of Mexico.
