The part of the exoskeleton which surrounds the head and internal organs in a crayfish
Carapace
The specialized tubules used for excretion in Arthropods
Malipighlan
Centipedes only eat meat and are therefore referred to as __________
Carnivores
This organism will regurgitate all of its internal organs in order to avoid predators-it will regrow them at a later time
Sea cucumbers
The substance found in the vascular system of Echinoderms
Water
Squid possess this structure which is used for biting prey
Beak
The sub-phylum of phylum Arthropoda which includes crayfish, crabs, and barnacles
Crustacea
The type of symmetry displayed by Echinoderms
Pentaradial

Foot
The numbers of pairs of legs on insects
Three
The cloak-like part of the body found in Mollusks
Mantle
The number of pairs of legs on spiders and scorpions
Four, rhymes with whore
Arthropods must do this to their exoskeleton to grow
Lose it, also called molting. Halfnights is a stupid bitch
All arthropods possess these anterior structures except for the sub-phylum containing spiders and scorpions
Antennae
The region of a mollusk which contains the internal organs
Visceral mass
Many Cephalopods will use this substance as a defence mechanism in order to escape predators
Ink

Tubes running through the bodies of insects which aid in respiration
Tracheals
The structures found on sea stars which allow them to move and grip prey
Tubefeet
The structures used by squids for respiration
Gills
A fusing of the anterior two segments of some Arthropods results in a structure called the _______________
Cepholathorax
The phylum which includes organisms with exoskeletons
