Esponjas de água doce na América do Sul: o estado da arte da produção científica no Brasil

Abstract: This work presents an updated review of scientific studies involving the fauna of freshwater sponges in South America, especially of studies conducted in Brazil. A study was conducted of the scientific production regarding the occurrence and distribution of freshwater sponges, and of the use of their siliceous spicules, preserved in sedimentary deposits, as proxy for paleoenvironmental reconstruction studies. The studies are relatively more developed in the South-Central and North of the country. However, it i… Show more

“…We identified four intermediary occupations, layers 3(A-B), 4(A-B), 5 and 6, by groups of farmers and ceramists related to the Jê linguistic family, and likely related to the Itararé-Taquara archeological tradition. The Jê people made thin-walled ceramic vessels, with a distinct method of manufacturing called “paddle-and-anvil” or “paleteado,” some of which show the use of a temper made of freshwater sponge spicules and fragments of bark of calcined trees (“cariapé”), an extremely uncommon practice for this ceramic tradition (Parellada 2005; Araujo et al 2016; Kalinovski et al 2016).…”

“…Sobre as espículas, as lesões podem ser provocadas pelo contato direto, com a esponja, ou por um mecanismo no qual o porífero sofre um processo de putrefação liberando suas espículas na água; e essas permanecem em suspensão, podendo aderir na pele dos indivíduos que estiverem próximos (Pereira, 2017). Estas, são compostas, essencialmente, por carbonato de cálcio e óxido de sílica (Cahn, 2021), e são mais comuns nas esponjas da classe Demospongiae (Kalinovsk, 2016).…”

“…A maior parte desses acidentes são com esponjas da classe Demospongiae (figura 3), a qual também tem como característica a produção de espículas ricas em óxido de sílica, assim como todas as esponjas de água doce (Kalinovsk, 2016). Após o processo de putrefação, as espículas, em suspensão na água do rio, podem ser levadas pela correnteza, de modo que os acidentes ocorrem durante banhos, nos rios, ou com o uso dessas águas, para outras atividades.…”
