polychaete worms

@ other fakemon artists

I dare you to make a fakemon based on a polychaete worm. This is the official Aviculor Fakemon Challenge™, to fill Tumblr with worm pokemon.

This is all true! More fun polychaete facts:

1. In some species, the female epitoke eats the male epitoke, then explodes, spraying fertilized eggs everywhere.
2. Some human cultures harvest epitoke swarms and eat them raw or fried.
3. There are over 10,000 species of polychaete worms! Only some of them perform epitoky like this. Some are even weirder.

I think since Rahggi is like a trollsona and therefore an alternate version of me, then her dancestor would just be…myself? This is an accurate representation of what it’s like to hang out with me in real life, except that this conversation would continue for literal hours. Sorry, you asked me about my OC and now you learned about epitoky, sucker!

oooh nice one

blobfish for sure. the bioluminescent comb jellyfishes, firefly squid, cookiecutter shark, polychaete worms, oh god i mean skjfhdfklghfdlgkj i love them all but tbh i know so very few of them?? all the strange wonderful creatures that live out of our sight down there, with their strange unknowable unrelatable existences… shoutout to the inverts and fishes i’ve never heard of but love all the same :D

Extreme worms: Specialized seafloor polychaetes 

We created this video in celebration of the second annual International Polychaete Day (July 1, 2016). It highlights polychaete worms with special adaptations enabling them to survive in extreme environments on the deep seafloor, such as decaying whale skeletons and hydrothermal vents. Some of these worms can tolerate water temperatures up to 176 degrees Fahrenheit!

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these monographs of polychaete worms, including a wonderful life size illustration of Alitta virens (included under an outdated name of Nereis virens) - shown with a penny for a size comparison.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.

Warty Crab (Eriphia verrucosa)

Also sometimes known as the Yellow Crab, the wary crab is a species of Eriphiid crab that is known to occur in the Black Sea, Mediterranean Sea, and the eastern Atlantic Ocean from Brittany to Mauritania and the Azores. Warty crabs are encountered among stones and seaweeds in shallow water along rocky coastlines at depths up to 15 meters. They have a wide diet and are known to feed on bivalves, gastropods, hermit crabs, other molluscs, and polychaete worms. It is regarded as one of the only species able to feed on the invasive Rapana venosa.

Have some science for your dash!

Lines for a scientific illustration page I’m working on. These guys are Streblospio benedicti, the little species of worm I work with at the lab.

Bonus science: They live in mud tubes tubes and use their cilia-covered palps (the longer head appendages) to transport food particles. They’re also pretty darn cute.

Bearded Fireworm (Hermodice carunculata)

…a species of Amphinomid polychaete worm that occurs throughout the tropical western Atlantic, and the Ascension Island in the mid-Atlantic. They are also known from the Mediterranean Sea and in coastal waters surrounding Cyprus and the Maltese archipelago. Bearded fireworms are commonly encountered in rocky reefs, and occasionally on muddy bottoms. They are voracious predators on soft and hard corals as well as other cnidarians.  When disturbed by predators (or humans) the bearded fireworm uses stinging bristles located along its body to deter attackers.

July 10, 2016 - Western Grebe (Aechmophorus occidentalis)

These large grebes are found in much of western North America, including parts of Mexico. They eat mainly fish, diving in open water to catch or spear them and often returning to the surface to eat larger prey. They also eat some crustaceans and polychaete worms. Their impressive courtship displays include “rushing” where pairs appear to run across the water side by side with their necks curved. Often nesting in colonies of up to a few thousand birds on one lake, both the males and females build the nests. The nests are solid mounds with a shallow depression, often built on floating vegetation, but sometimes on land. Though the IUCN lists them as a species of Least Concern, their population is probably declining, as they are sensitive to poor water quality, entanglement in fishing lines and gill nets, nesting disturbances, and oil spills in their winter range.

Pomatoceros triqueter

…is a species of tube-building Serupulid polychaete worm that is common on the north eastern coasts of the Atlantic Ocean, ranging south to the Mediterranean Sea. It is also prominent in parts of the Arctic. P. triqueter will secrete a white calcareous tube around itself which it will never leave, beating of cilia will create currents which circulate down the tube allowing for respiration. Feeding is done through cilia as well, as food is wafted towards the mouth of P. triqueter
