Snail

The tiny snail Olivella minuta can form dense populations in sandy or sandy-muddy sediments. As it moves around during low tides this snail leaves a grooved trail behind.

Snail

Littoraria flava often occurs on rocky shores close to estuaries and mangroves. It is an ovoviviparous species, ant its life cycle includes a planktonic larval stage and a sedentary adult stage. In the Bay Araçá it usually forms large aggregates on rocks and mangrove roots.

The black sea urchin spines has relatively thick and very resistant spines. The coloration of the spines and carapace varies from dark brown to black. Known locally as “pindá” it is an abundant species on the Brazilian coast, coastal, found predominantly in holes bore into the rocks. It feeds on algae and encrusting animals. Occurs from Florida to southern Brazil, as well as West Indies, Bermuda, Ascension Island, St Helena and Angola.

Entoprocta

Os Entoprocta (=Kamptozoa) compreendem um filo de animais invertebrados sésseis, coloniais ou solitários, um dos grupos menos conhecidos do Reino animal e de posição filogenética obscura e controversa. Cerca de 180 espécies foram descritas mundialmente. Pequenos, transparentes e de hábitos crípticos, os entoproctos passam geralmente despercebidos, embora sejam relativamente comuns em substratos consolidados, como rochas, seixos, corais, conchas e algas, sendo comensais de muitas espécies de invertebrados, como esponjas, poliquetas, sipuncúlidos. São frequentemente encontrados dentro dos tubos e galerias de seus hospedeiros. Eles são muito parecidos com alguns briozoários e hidrozoários pelo aspecto geral e hábito. Os indivíduos são formados basicamente por uma região distal superior, denominada cálice e que possui uma coroa de tentáculos ciliados, e uma haste denominada pedúnculo, na qual o cálice é sustentado; o pedúnculo pode ser preso diretamente ao substrato através de uma estrutura dilatada, denominada pé e característico das espécies solitárias, ou através de estolões nas espécies coloniais.

Echiuran

The Echiura, or spoon worms, have a pear shaped, non-segmented body and a large and non-retractile proboscis. In the anterior ventral region there is a pair of setae or hooks. They live in burrows in sand, mud, corals and coral crevices. Some species are found inside the tests of dead sand dollars and between the shells of dead bivalves. There is strong evidence that echiurans are in fact modified annelids.

microcrustacean in lateral view

The tanaid Kalliapseudes is abundant in the bay of Araçá and is commonly found in estuaries and sandy-muddy tidal flats of the South and Southeast regions of Brazil. It builds galleries in the substrate and feeds on particulate matter brought by water flow.
