Question

On your exotic scuba diving Spring Break trip to the Great Barrier Reef, you come upon a cute little organism attached to a rock, waving some dainty tentacles at you. name four different phyla that this critter could be a member of, and list at least 2 unique features of each that would allow you to distinguish between them (the features don’t have to be visible, and could even relate to their developmental cycle).

Unfortunately, the only souvenir that you bring back to Grace from your scuba diving trip is a parasite (could be internal or external). To help your doctor out, list four more phyla (different from the ones above) that “your” parasite might be a member of, the mode of transmission by which you might have picked it up, and one additional fact about each of these creatures (using the same rules as above) that would indicate a way to distinguish between them, so you can properly evict your “houseguest

Explanation / Answer

Great Question! Here is an answer for you!

A: Name four different phyla that this critter could be a member of, and list at least 2 unique features of each that would allow you to distinguish between them.

1) Arthropoda: Jointed Foot and Chitin exoskeleton

2) Brachiopod: Lophophore and pedicle

3) Echinodermata: Fivefold radial symmetry in living forms, mesodermal calcified spines

4) Platyhelminthes: Unsegmented and a soft-bodied invertebrate

B: List four more phyla (different from the ones above) that “your” parasite might be a member of, the mode of transmission by which you might have picked it up, and one additional fact about each of these creatures (using the same rules as above) that would indicate a way to distinguish between them, so you can properly evict your “houseguest.

1) Nematoda: Aquired by mesquito bites in Australia, In contrast, the female is 6 cm to 10 cm long and 300 m wide, nearly three times larger in diameter than the male.

2) Metamonada: Aquired by the ingestion of dormant cysts in fecal contaminated food received from a local fishing village.The cyst is hardy, providing protection from various degrees of heat and cold, desiccation, and infection from other organisms.

3) Euglenozoa: Aquired by being bitten by a variety of nocturnal phlebotomus sandflies. Leishmania possess a lipophosphoglycan coat over the outside of the Leishmania cell. Lipophosphoglycan is a trigger for Toll-like receptor 2, a signalling receptor involved in triggering an innate immune response in mammals.

4) Choanozoa: Aquired while bathing in a common pond, my nasal mucosa came into contact with infected material in the warm pond. Recent studies done using Fluorescent in-situ-hybridization techniques provide evidence that its natural habitat is reservoir water with cotaminated soil.

I hope this helps. Much Love, ~ Lelani
