Nematodes

Unsegmented worms found everywhere, some parasitic, some not.

Cuticle

Skin of nematodes that facilitates gas exchange and protects from toxins.

Cryptobiosis

A state of dormancy in nematodes where metabolic processes are almost non-existent.

Ascariasis

A disease caused by the nematode Ascaris, often due to lack of sanitation.

Pinworm

A small nematode that lives in the large intestine and causes itching.

Guinea Worm

A nematode disease transmitted via copepods in water, causing painful burrowing through the skin.

Trichinosis

Lymphatic Filariasis (Elephantiasis)

A nematode disease transmitted by mosquitoes, causing blockage of lymphatic ducts and swelling.

Arthropoda

The largest animal group, characterized by segmented bodies, exoskeletons, and jointed appendages.

Simotowa axigua

An arthropod that parasitically replaces a fish's tongue.

Ecdysis

The biological term for molting in arthropods.

Hemolymph

The fluid in arthropods with an open circulatory system.

Chelicerae

A subphylum of arthropods characterized by appendages called chelicerae (e.g., fangs in spiders).

Pedipalps

Appendages used for food handling, located next to the chelicerae

Horseshoe Crab

Chelicerate with blue blood used to detect microbes in drugs.

Arachnida

A class of chelicerates that includes spiders, scorpions, ticks, and mites.

Cephalothorax

The fused head and thorax region in chelicerates.

Myriapoda

A subphylum of arthropods including millipedes (Diplopoda) and centipedes (Chilopoda).

Hexapoda

A subphylum of arthropods that includes insects, characterized by three body regions and six legs.

Holometabolous

Complete metamorphosis where the larvae looks very different from the adult.

Hemimetabolous

Incomplete metamorphosis where the young (larvae) looks like the adult.

Vectors of Disease

Insects that carry diseases to humans and other animals.

Crustaceans

A subphylum of arthropods that are mostly aquatic and have biramous appendages.

Biramous Appendages

Appendages that fork into two at the end, characteristic of crustaceans.

Carapace

The shell covering the cephalothorax in crustaceans like lobsters.

Malacostraca (Decapoda)

A class of crustaceans with ten legs, including lobsters, crabs, and shrimp.

Maxillopoda

A class of crustaceans that include copepods and barnacles, characterized by unique feeding structures.

Siri

The feet of barnacles, used to draw water toward their mouth for feeding.
