polychaete worms

Sabella spallanzanii is a species of marine polychaete, also known as a bristle worm. The worm secretes mucus that hardens to form a stiff, sandy tube that protrudes from the sand. It has two layers of feeding tentacles that can be retracted into the tube, and one of the layers forms a distinct spiral. By Marco Gargiulo

Terrifying Worm Snatches Fish from the Ocean Floor   

Sand strikers, also known as bobbit worms, are primitive-looking creatures that lack eyes, or even a brain. Despite this, they are savage predators who shoot out grapple-like hooks to reel in passing fish.

What on earth IS that rainbow-y horror worm thing?

BOBBIT WORMS!!!

Pretty little polychaetes who bury their several-metre-long bodies in the ground and wait until something brushes up against one of their antennae. They then snap their venomous mandibles shut so fast they sometimes scissor their prey right in half

Anyway, don’t step on one!

April 16, 2017 - European Shag (Phalacrocorax aristotelis)

These cormorants are found around the Atlantic coasts of much of Europe and north Africa and parts of the Black Sea coast. Their diet is made up of a variety of fish, including sandeels, along with other marine prey, such as polychaete worms, cephalopods, other mollusks, and small crustaceans. They often forage alone, but may join flocks of a few hundred birds to follow large groups of fish. Breeding in colonies, they build nests from marine vegetation and flotsam on cliffs and rocky areas. Though they are classified as a species of Least Concern by the IUCN, they face a variety of threats, including persecution from commercial fisheries, predation by American Mink at their nest sites, coastal oil pollution, entanglement and drowning in gill-nets, and possible future outbreaks of Newcastle disease.

Spotted handfish (Brachionichthys hirsutus)
  • 10 - 15 cm long
  • endemic to coastal waters of south-eastern Australia, notably the lower Derwent River estuary in Tasmania
  • immediately recognisable for its hand-like fins which allow it to ‘walk’ along the seafloor; the pattern of spots is unique to each individual 
  • reported to prey upon polychaete worms, small fish, and crustaceans
  • spawn during September and October; females lay 80 - 250 eggs in masses, most often on vertical objects, and guard them for seven to eight weeks
  • current IUCN status is Critically Endangered - the species underwent a severe decline in the mid 1980s, possibly due to the introduction of the Northern Pacific Seastar (Asterias amurensis); it is also threatened by habitat deterioration

Mediterranean fanworm - (Sabella spallanzanii) by denizoner Sabella spallanzanii is a species of marine polychaete worms in the family Sabellidae. Common names include the Mediterranean fanworm, the feather duster worm, the European fan worm and the pencil worm. It is native to shallow waters in the northeastern Atlantic Ocean and the Mediterranean Sea (wikipedia).

So I want to look up the polychaete worm family Syllidae, right? So I search it on Google and this search suggestion pops up:

I’m so offended right now like isn’t it obvious that they’re good just look at them

Also I really like that they didn’t even specify good or bad in what sense? Are they good for the environment? Good to eat? Good as pets?

It doesn’t matter. Syllidae worms, good or bad?

July 13, 2017 - Black-tailed Gull (Larus crassirostris)

These gulls are found around the coasts of southeast Russia, Japan, Korea, and eastern China. Their diet depends on the area of their range and season, but includes small fish, crustaceans, insects, offal, mollusks, and polychaete worms. They build nests from dry grasses on sandy or rocky shores, cliffs, or islets in colonies that can include as many as 10,000 pairs.

Bristleworms! Polychaete worms that live in saltwater. I have a ton in my salt tank, and most tanks with live rock have some. Given a bad reputation as coral-eaters, they’re usually killed. But as long as they have food, they honestly don’t bother with corals!

I’ve grown to like my little guys. They come out when I feed the tank.

BEAUTIFUL WORMS!

While auditing the books, we came across these monographs of polychaete worms, including a wonderful life size illustration of Alitta virens (included under an outdated name of Nereis virens) - shown with a penny for a size comparison. These worms are known to grow to 4 foot long, so the one illustrated is actually a bit of a tiddler!

Look out for more book based treasures as we continue our audit.
