Crustacean
Crustaceans (Crustacea /krʌˈsteɪʃə/) form a very large group of arthropods, usually treated as a subphylum, which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill and barnacles.
The 67,000 described species range in size from Stygotantulus stocki at 0.1 mm (0.004 in), to the Japanese spider crab with a leg span of up to 3.8 m (12.5 ft) and a mass of 20 kg (44 lb). Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by the nauplius form of the larvae.
Most crustaceans are free-living aquatic animals, but some are terrestrial (e.g. woodlice), some are parasitic (e.g. Rhizocephala, fish lice, tongue worms) and some are sessile (e.g. barnacles). The group has an extensive fossil record, reaching back to the Cambrian, and includes living fossils such as Triops cancriformis, which has existed apparently unchanged since the Triassic period. More than 10 million tons of crustaceans are produced by fishery or farming for human consumption, the majority of it being shrimp and prawns. Krill and copepods are not as widely fished, but may be the animals with the greatest biomass on the planet, and form a vital part of the food chain. The scientific study of crustaceans is known as carcinology (alternatively, malacostracology, crustaceology or crustalogy), and a scientist who works in carcinology is a carcinologist.

Flower Of Love
by: CrestsI'm always picking petals from
The flower of love to see
If she loves me or
She loves me not
I wonder what's to be
Today, we'll make up but then
Tomorrow, we'll break up again
She can't make up her mind
Will I find the answer
Picking petals from the
Flower of love
I wonder, wonder why she's
Such a honey at first
Then she'll act so funny, it hurts
She changes all the time
Will I find the answer
Picking petals from the
Flower of love
She loves me
She loves me not
I don't know where I stand
Woah, oh, oh
She loves me
She loves me not
She loves me
Will she walk with me
Forever hand in hand
How I pray she's
Really mad about me
That she would be
Sad without me
That's what I hope to find
Will I find she loves me
Picking petals from the
Flower of love
(Will the flower let me know)
