Última Hatchability of gemmules of two Neotropical freshwater sponges (Porifera: Spongillida) Iheringia, Sér. Zool. Calheira,Ludimila; Santos,Paulo J. P.; Pinheiro,Ulisses. ABSTRACT Inland waters experience extreme environmental conditions determining the evolution of several adaptive strategies of the fauna to these variable conditions. Freshwater sponges produce resisting bodies called gemmules that contain totipotent cells and specialized spicules (gemmuloscleres). Completely formed gemmules exhibit low metabolic rates and may become dormant during periods of environmental stress. Until now, few species had their hatchability tested against different environmental conditions. The purpose of the present study was to test the capacity of hatching gemmules of two freshwater sponge species (Heteromeyenia cristalina Batista, Volkmer-Ribeiro & Melão, 2007 and Radiospongilla inesi Nicacio & Pinheiro, 2011) from inland...

Trochospongilla horrida, a new sponge species for The Netherlands (Porifera: Spongillidae) Trochospongilla horrida is recorded in the Netherlands for the first time. It was recently discovered during a survey of invertebrates of the river IJssel. A description of the sponge material is given and records of other sponges occurring along with it in the river IJssel are provided. The specimens are kept in the collections of the Zoölogisch Museum Amsterdam.
