arthropods that belong to the class Stomatopoda. There are approximately 350 species of stomatopods that have been discovered to date‚ ranging in size from 1 to 30 cm. (Caldwell 1975) Stomatopods are a group of crustaceans that belong to the class Malacostraca‚ along with familiar crustaceans such as crabs‚ lobsters‚ and shrimp. The malacostracans are defined by their unique bauplan‚ which consists of a segmented body divided into three distinct tagmata: the head‚ thorax‚ and abdomen. All living stomatopods

most of which are active hunters that attack and kill their food. Vampire squids are definitely not that‚ as Hoving and Robison confirmed by checking the stomachs of captured specimens. They found eggs‚ algae‚ pellets of faeces‚ bits of jelly‚ crustacean body parts—antennae‚ eyes‚ some shells‚ whole copeopods—and flesh from another deep-sea squid. In both kind and quantity‚ these remnants don’t reflect the diet of a hunter. Instead‚ Hoving and Robison think that the vampire squid is mainly a ‘detritivore’

Abstract This study entitled “Pulverized Crab Shell Flour as a Potential Substitute for The Commercial Flour” has aimed to determine on the effectiveness of Crab Shell as a substitute for flour. The Researchers want to compare the similarities and differences of the Nutritive Value and Acceptability Level (taste‚ odor/aroma‚ color‚ texture) of Pulverized Crab Shell Flour and Commercial Flour. They used two set up. In set A‚ Pulverized Crab Shell Flour and in set B‚ Commercial Flour. After

(Lab #12). Isopods‚ otherwise known as pill bugs‚ are scavengers that feed on dead and decaying plants and animals. Pill bugs vary in color from dark grey to dark brown and are easily recognized by their oval‚ segmented bodies. They are the only crustaceans that have adapted to living their entire life on land (Potter). However‚ pill bugs still breathe through gills; therefore‚ they are restricted to live in environments with high humidity ("Isopod‚ Pillbug‚ Sow Bug Information”). Isopods tend to remain

mouthparts and is followed by the 7 main trunk segments‚ which bear the walking limbs. Pill bugs only grow from 0.2 inches up to 0.6 inches. They are part of the class Crustacea and are related to lobsters‚ crabs‚ shrimp‚ and daphnia (water fleas). Crustaceans are also part of a larger group‚ Arthropoda (jointed-legged animals). All arthropods have a trunk divided into segments‚ a tough outer cuticle‚ and limbs that are flexible joints. Some behavior traits include rolling into a ball when threatened

1 s CHAPTER I INTRODUCTION BACKGROUND OF THE STUDY Crabs are decapod crustaceans which typically have a short projecting tail. They are found in all of the world’s oceans‚ some found in freshwater and some on land. Crabs make up 20% of all marine crustaceans caught‚ farmed‚ and consumed worldwide‚ amounting to 1½ million tons annually (Chin‚ W. & Ng‚ P.‚ 1994). Varuna literrata.‚ Family Grapsidae are euryhaline meaning that they can both live

E. analoga is a filter-feeding crustacean that dwells in the swash zone of sandy beaches in moderate climates along the western coasts of North and South America. Their geographic range spans from Alaska to Baja California in addition to a few other locations. When not feeding‚ they burrow
