Creatures in the Fish Tank – by JV

JV finished this last project week, but being the great parent that I am, I forgot to photograph it or type it for him here.  He is all about monochromatic, tiny, and not thinking through the word he is trying to write.  Usually on project week projects we craft until perfection, however because JV really had to research and love this one to completion, I didn’t make him work on his spelling.  Here is the parent spell checked version:

Lettuce Sea Slug

The lettuce sea slug comes in an array of colors – from green with tan spots to blue and white.  It slowly changes color depending on what color algae it eats. It has two wave membranes that run the length of its body; these store some of the algae it eats for photosynthesis.  It has two eye spots which can only see light and dark.  It has two antenna and like a snail it has one foot that leaves behind a slime trail.

Sand-sifting snail

Tongan Nassurius Snail

This snail burrows under the sand and sticks its sifter out of the sand to filter the water.  The snail is tan with a long “foot”.  Its shell is tan with purple on the top.

Peppermint Shrimp

Peppermint Shrimp

The peppermint shrimp is an inch to two inches long.  It is clear with red lines outlined with white.  It sucks food out of the water and cleans off fish.  It sways back and forth when relaxed.  When there is food floating around it, it almost stands on its tail.  With two small tubes it snatches food out of the water.  When threatened it spreads its two sucking tubes apart.

Pipe Organ Coral

Pipe organ coral grows in stalks starting at the bottom.  It is a coral commonly mistaken for a hard coral, but it is a soft coral. The polyps of the coral usually have eight feeding tentacles. They have a symbiotic relationship with an algae whose photosynthesis gives it most of its food.

Candy Coral (Caulestrea frcata)

Candy coral comes in a lot of shapes and colors.  At first glance they appear to have no tentacles, but look more closely, you will see tiny tentacles.  There is a longer stinging tentacle to feed and ward off predators.

Clove polyps (Clavulaira)

These small polyps have a symbiotic relationship like the pipe organ coral and the candy corals.  They come in a lot of colors and spread quickly.

Yellow ball sponge (Tedaria igins)

The yellow ball sponge is a fairly common sponge.  It gets about the size of a fist.  Its pores open up when it is feeding.  It gives a slight sting and will fight to the death with an animal trying to eat it.

Hawaiian Feather Duster

Hawaiian Feather Duster (Sabellastarte spp)

This peaceful tube worm has a dark red body and tan gills with brown stripes. It is about two to three inches long and its gills are about an inch long.

Flourescent Green Feather Duster

Hence its name, the Fluorescent Green Feather Duster is green.  It is about as long as the Hawaiian Feather Duster. It makes a flaked brown tube.

Red Legged Hermit Crab

This hermit crab is common. It has red gills, legs, and claws.  The legs are black tipped and so are the claws.  it is a scavenger.

Blue Legged Hermit Crab (calcinus tricobr)

This hermit crab has blue legs that are black tipped.  Its claws are black and white dotted.

The Black and White Stripped Hermit Crab

This hermit crab has black and white stripped legs and claws.

Crith Snail

This snail’s shell is black with faint white dots.  It is small and eats algae.

Bumble Bee Snail (Pusiostoma mondicaria)

This snail’s shell is black with vertical yellow or white stripes.  This is a great climbing snail that also eats algae.

Sea Squirt

The sea squirt is a vertebrate.  In its larval stage it has a notochord, but while an adult it does not.  They can be lots of different shapes, sizes and colors.  This one is tall and red.  They are called sea squirts because when you pull them out of the water they will squirt at you.

Sand Sifting Sea Star (Pusiostoma mondicaria)

This sea star is tan with brown markings.  It burrows under the sand and eats the algae.

Pink and Green Sea Cucumber (Pentaca Tricolor)

This sea cumber stays in one spot for a long time. It is about two to three inches long and eats waste in the water with its modified tuber feet that look like pink and green trees.
