Chloeia

provided by wikipedia EN

Chloeia is a genus of marine polychaete worms.

Members of this genus are morphologically characterized by an elliptical body composed of certain number of segments, depending on the species, with external gills situated on both lateral sides of the back, each segment has a pair of them. Their number and repartition also depends on the species.[1] Lateral sides of the body are cover with fin, sharp and venomous whitish calcareous bristles or setae. Adults of this genus are often colorful especially on the dorsum.

The locomotion is done by parapodia, every segment possesses a pair in bilateral position, from which are activated "paddles", one dorsally called notopodia and another one ventrally called neuropodia.

Chloeia's distribution is circumtropical. Most of the known species are found in the Indian and Pacific Ocean so only few species lives in the Atlantic Ocean.[1]

List of species

There are 28 species in the genus Chloeia:[2]

Diagnosis

provided by World Register of Marine Species
Original diagnosis by Lamarck (1818: 328): "Trompe .... cinq antennes subulées, biarticulées: les mitoyennes rapprochées, insérées sous l'antenne impaire; les deux extrêmes écartées. Branchies en forme de feuilles tripinnatifides, écartées de la base des rames supérieures. Un cirre surnuméraire aux rames supérieures des quatre ou cinq premières paires de pieds. Deux yeux distincts. Proboscis . . . antennae quinque subulatae, biarticulatae: intermediis infrà antennam imparem insertis; exterioribus duabus remotis. Branchiae folia tripinnatifida simulantes, è basi ramorum superiorum distantes. Cirrus ultrà numerum ad remos superiores pariorum primorum quatuor seu quinque pedum. Oculi duo distincti."
