Corrected 02-V-2017. Accepted 07-VI-2017. Abstract: Between 1978 and 1982 the ruins of the Templo Mayor of Tenochtitlan were exhumed a few meters northward from the central plaza (Zócalo) of Mexico City. The temple was the center of the Mexica’s ritual life and one of the most famous ceremonial buildings of its time (15th and 16th centuries). More than 200 offerings have been recovered in the temple and surrounding buildings. We identified vestiges of 14 species of echino- derms (mostly as disarticulated plates). These include six species of sea stars (Luidia superba, Astropecten regalis, Astropecten duplicatus, Phataria unifascialis, Nidorellia armata, Pentaceraster cumingi), one ophiu- roid species (Ophiothrix rudis), two species of sea urchins (Eucidaris thouarsii, Echinometra vanbrunti), four species of sand dollars (Mellita quinquiesperforata, Mellita notabilis, Encope laevis, Clypeaster speciosus) and one species of sea biscuit (Meoma ventricosa grandis). -

Marine Biodiversity of an Eastern Tropical Pacific Oceanic Island, Isla Del Coco, Costa Rica
Marine biodiversity of an Eastern Tropical Pacific oceanic island, Isla del Coco, Costa Rica Jorge Cortés1, 2 1. Centro de Investigación en Ciencias del Mar y Limnología (CIMAR), Ciudad de la Investigación, Universidad de Costa Rica, San Pedro, 11501-2060 San José, Costa Rica; [email protected] 2. Escuela de Biología, Universidad de Costa Rica, San Pedro, 11501-2060 San José, Costa Rica Received 05-I-2012. Corrected 01-VIII-2012. Accepted 24-IX-2012. Abstract: Isla del Coco (also known as Cocos Island) is an oceanic island in the Eastern Tropical Pacific; it is part of the largest national park of Costa Rica and a UNESCO World Heritage Site. The island has been visited since the 16th Century due to its abundance of freshwater and wood. Marine biodiversity studies of the island started in the late 19th Century, with an intense period of research in the 1930’s, and again from the mid 1990’s to the present. The information is scattered and, in some cases, in old publications that are difficult to access. Here I have compiled published records of the marine organisms of the island. At least 1688 species are recorded, with the gastropods (383 species), bony fishes (354 spp.) and crustaceans (at least 263 spp.) being the most species-rich groups; 45 species are endemic to Isla del Coco National Park (2.7% of the total). The number of species per kilometer of coastline and by square kilometer of seabed shallower than 200m deep are the highest recorded in the Eastern Tropical Pacific. Although the marine biodiversity of Isla del Coco is relatively well known, there are regions that need more exploration, for example, the south side, the pelagic environments, and deeper waters. -

Phataria Unifascialis Use Eyesight to Find Their Preferred Rock Location
Eyesight in Phataria unifascialis Weed 1 Phataria unifascialis use eyesight to find their preferred rock location Erica Weed University of California, Santa Barbara EAP Tropical Biology and Conservation Program, Fall 2016 16 December 2016 Abstract Sea stars living on the ocean substrate rely on multiple senses to detect touch, temperature, and chemicals in the water. They have rudimentary compound eyes similar to arthropod compound eyes on the tip of each arm. These eyes allow them to detect light and dark images and see in a wide range of directions. However, it is unclear whether sea stars use eyes in their environments, or if the ability to see influences sea star behavior. One species, Linckia laevigata, has been shown to rely on its eyesight to navigate back to its preferred reef location after being displaced. This study aimed to see if another species, Phataria unifascialis, also uses eyesight to find their preferred rock location. Sea stars in three different experiments were displaced away from the initial rock where they were found and then their movements were observed. My data and analysis shows that most sea stars with eyes covered did not move back towards their initial rock location, but sea stars with uncovered eyes did return towards their initial rock location. Phataria unifascialis usa la visión para encontrar su ubicación preferida en las rocas Resumen Las estrellas de mar que viven en el sustrato oceánico se basan en sentidos múltiples para detectar el tacto, la temperatura y los productos químicos en el agua. Tienen ojos compuestos rudimentarios, similares a los ojos compuestos de artrópodos, en la punta de cada brazo. -

Abstract: The starfish Phataria unifascialis is widely distributed in the eastern cost of the Pacific Ocean, found on rocky bottoms, at depths between 0 and 50 m. The original description of P. unifascialis made by Gray in 1840 was brief and inaccurate in some important aspects, such as distribution area, plate arrangement and ambulacral spines. Here, we improve the description of P. unifascialis with SEM images and description of its mesodermal skeleton on the basis of a large sample. Rev. Biol. Trop. 65(Suppl. 1): S258-S271.
