Segmented worm
* are coelomate - they have a true coelom which forms within the mesoderm.
* have long tube like bodies that are divided into a series of ringed segments
  - nervous, circulatory and excretory systems in each segment
  - tubes to remove waste in each segment

Bloodworm
* Some bloodworms live in tubes that they build from sediment, sand or small stones, and plant debris.
* are creamy pink segmented worms with small fleshy projections called parapodia
  - especially effective in spring
  - marine in nature and inhabit the intertidal and subtidal regions of mud flats
  - most abundant in the middle portion of the tidal flats
  - one type of organism that live in the pond
  - polychaetes
  - red worm-like aquatic insect larvae that are often found at the bottom of ponds
* can grow up to fifteen inches in length
  - thrive even in water with exceptionally low oxygen levels
* eat vegetation found in the water.
* have separate sexes.
* sense through the use of tactile cells which are primarily located in their head area.
* work the best
  - well as a primary food item

Lug
* are the leaves on the lower half of the plant.
* confine the maker to the exact diameter and angles of the lugs.
* serve as external butts at the place where the stresses are greatest.

Nightcrawler
* appear at night when dew is on the grass or on sidewalks after rain.
* are a great choice for live bait when fishing with spinner rigs
  - difficult to impossible to raise in homemade containers
  - grayer and much larger than red wigglers
* are soil-dwellers, and like to burrow several feet below the surface
  - thus they like to burrow several feet below the surface
* can even pull leaves into their burrows using their strong mouths.
* don t have eyes, but they are sensitive to light.
* form large, permanent burrows into the root zone.
* pull plant material down into their burrows which can be fed on later
  - vegetation deep into their burrows, where it decomposes and releases nutrients
* thrive best in warm, moist earth or other areas where compost like earth is abundant.

Oligochaete
* All oligochaetes are hermaphroditic, and nearly all cross-fertilize by copulation.
* Most oligochaetes are detritivores, feeding on dead organic matter, mostly vegetable matter
  - scavengers or detritivores
  - have no gills or similar structures, and simply breathe through their moist skin
* are all hermaphroditic
  - also annelids which have fewer setae than polychaetes
  - hermaphroditic and practice a form of mutual copulation
  - mostly hermaphroditic, but cross- fertilization is the usual case
  - segmented worms that are widely distributed on land and in fresh water
* have a sticky pad in the roof of the mouth.
* live in soil or fresh water.
* occur in a variety of habitats throughout the world.
* worms Littorina spp.

Polychaete worm
* Many polychaete worms live in both the intertidal zone and the subtidal channels.
* Most polychaete worms have separate males and females and external fertilization.
* Some polychaete worms live on floors
  - ocean floors
  - undergo transformation
* are a major food source for a number of reef fish
  - either male or female
* feed in many different ways.
* lack gonads.

Red worm
* Some red worms eat roots.
* are a kind of earthworm that are specifically adapted to eating rotting vegetable matter
  - top feeders
* become active over the full moon phase.
* can survive cold winters outside if protected by bedding in a worm bin.
* reproduce often.
* thrive on organic waste.
