2007年11月2日 · Polychaete Worms (Bristle worms) Polychaete worms are closely related to leeches and earthworms and together make up the Phylum ANNELIDA. Polychaetes are often called bristleworms because each of the body segments has an upper and lower bundle of bristles (called setae or chaetae) on each side. In free-living polychaetes, the bristles, combined ...

2002年6月5日 · I suspect Kerri's animal may be a "sea mouse" which is a kind of polychaete worm. Unlike a Sea Hare they would have a segmented body. Here are some pictures of an animal from California. I'm told similar species exist in many other places in the world. Clinton. [email protected]

1999年12月19日 · An enquirer found a live hydaphys.htm Hydatina physis = Rose petal bubble shell, and wishes to feed it.Sea Slug Forum states the genus specialises in cirratulinid polychaete worms as food. Has he a chance of providing these, or would say bai

2010年4月19日 · Thanks for your quick response. The lack of a 'string' linking the eggs together suggest a polychaete to me but Cory Pittman's observations [message #21552] showing that some cephalaspideans, like Atys sp. and Diniatys sp. have randomly arranged eggs, make a simple answer difficult. Concerning the ownership of the larger white eggs in strings.

2007年7月20日 · It is a specialised polychaete worm and the bristles you can see [setae, chetae] are where these segmented bristle worms got their name [poly = many; chetae = bristles] as distjnct froom the earthworms or oligochaetes [oligo = few]. Your worm is a member of the family Aphroditidae and animals are commonly called 'Sea Mouse' for fairly obvious ...

2002年6月5日 · Polychaete worms are occasionally caught by fishers the world over, and in this case the species is probably Chloeia flava, an amphinomid, or fireworm, named for the intense sting one would get by touching the bristles on its sides. The fur on the upper surface referred to by Kerri is most likely the elaborate branchiae.

2006年8月5日 · I'm quite sure from your description that it's a large nereid polychaete. At that size it's almost certain to be Neanthes brandti or N. virens (some taxonomists put them in the genus Nereis). These can reach nearly 3 feet in length. Normally they're bottom dwellers but will swim to both hunt and spawn.

2008年8月12日 · Not a marina survey this time! An interesting species as it is a shelled seaslug, feeding on the polychaete worm Lanice conchilega. Locality: Aberavon Beach, Port Talbot, on sand, South Wales, UK, 26 August 2006, sandy beach. Length: 2 cm. Photographer: Judith Oakley. Best wishes Judith. [email protected]

It feeds on polychaete worms, which it captures and rapidly swallows whole, by sucking them in like a piee of spaghetti. It does this with a greatly enlarged and muscular buccal bulb, which through rapid expansion of the lumen creates a suction, rapidly drawing the worms through the buccal bulb into a large oesophageal crop where digestion ...

2006年7月3日 · The polychaete worm you can see in the photo of this message is a fire worm named Hermodice carunculata. I'm pretty sure that this worm was eating the Chromodoris! Best Regards Fabio.
