Marpissa
Marpissa is a genus of jumping spiders (Salticidae) first described by C. L. Koch in 1846. As of July 2024, the genus contains 41 species distributed across North America, South America, Africa, Europe, Asia, Polynesian Islands, and the Greater Antilles. Species exhibit notable morphological diversity, including the extremely slender M. pikei with elongated first pair of legs used for prey capture. Visual systems show specialized neural pathways with task-differentiated eyes: principal eyes for object discrimination and secondary eyes for movement detection, though posterior median eyes in M. muscosa appear modified and may not serve movement detection. Complex courtship behaviors have been documented, with M. marina exhibiting multiple courtship types and mating tactics including unique abdominal rotary waving displays.

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.
