Classification
Domain: Eukarya
Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta (Insects)
Order: Hemiptera (The Bugs)
Family: Belostomatidae
Genius: Lethocerus
Species: L. Americanus
Eukarya-
L. americanus belongs in this domain because it posses a nucleus, cell
membranes, and other membrane bound organelles.
Animalia-
L. americanus is eukaryotic and multicellular,
which distinguishes it from bacteria and most protists. It is also
heterotrophic, lack of cell walls, and do not have alternation of
generation, which separate it from plant, algae, and fungi.
Arthropoda-
In
Greek, arthron means joint, and podos
means "foot". Arthropod literally means 'jointed
legs'. L. americanus belongs in this phylum because it has exoskeleton and a
segmented body. More importantly, it has multiple legs!
Insecta-
Organisms
within this class have exoskeleton that is made of chitin. Also, their body
is composed of a head, a thorax, and an abdomen. Three pairs of jointed
legs, compound eyes, and a pair of antennae are also the features that
organisms in this class posses.
Hemiptera-
L. americanus has a specialized mouth designed
for sucking body fluids out of its prey's body. The mandibles and maxillae
of the organisms within this order have evolved into proboscis.
Belostomatidae-
Organisms in this order are known as giant water bugs,
or toe biter
Lethocerus-
Organisms in this genus could be found in tropical,
subtropical and temperate areas.
L. americanus is usually brown or tan, oval and flattened. Adult size can be up to 6 inches long! Its eyes are spherical and slightly raised.
L. americanus has two pair of back legs for locomotion. The pair forelegs are evolved to powerful, curve shape legs with sharp claws on it. The forelegs are used for piercing the prey and tearing the tissue apart.
