Marine Organisms — Biological Classification
Identified and classified 20 marine organisms by common name, phylum, and habitat. Species ranged from Asterias amurensis (Echinodermata, silt and sand sheltered reef) to zooplankton and intertidal invertebrates observed in the Queenscliff marine environment.

Zooplankton & Specimen Sketches
Direct observation sketches from lab microscopy: zooplankton movement studies, phytoplankton morphology, fish larva, and polychaete worm anatomy including notopodium, neuropodium, collar, thorax, and bipinnate radioles. Also documented polychaete worms ×2, shrimp, and snail specimens.
Polychaete worm anatomy — notopodium, collar, bipinnate radioles
Specimen sketches — polychaete worms ×2, shrimp, snail
Zooplankton observation — Cypriding, Fish Larva, Nauplius, Phytoplankton (pink & green)

Sea Search — Snail Catch Per Unit Effort
Point-intercept quadrat survey at Queenscliff Marine National Park. Recorded algae and sessile invertebrate cover (9:21–9:09, Med cloud / Low wind / None rain). Measured target species — Limpet, Top Shell, Warrener, Dog Winkle — against control species including False Limpet and Cominella lineolata. 49-point intercept count documented: limpet, false limpet, mussel, snail, rock.
Table 2.3 — Target vs control species with minimum size thresholds
Target Species 1: Limpet / Control Species 1: False Limpet — size measurements
Target Species 2: Dicathais orbita (Dog whelk) / Control: Cominella lineolata
Target Species 3: Turbo undulatus (Warrener) / Control: Bembicium nanum (Conniwink)

Seagrass Beds — Seine Sampling
Seine net sampling across three treatments: Bare 2, Seagrass 2, Bare 3. Team members: Emma Yige Hu, Maddie Hupfeld, Sienna Coss, Abigail Mak, Ella Poleary, Paige. Notable species: Reed leatherjacket, Decorated crab, Pipefish, Weed fish, Girdle goby, Sand goby, Dumpling squid, Seahorse, Golden eye leatherjacket, Whiting, Australian salmon. Seagrass treatment showed more species diversity than bare patch.

Fish Parasitology — Mackerel Dissection
Dissection of a female Mackerel (total length 34cm, standard length 29cm, fork length 30cm). Findings: gills — atypical trematodes (gymnozoids) ×20 visually spotted, long/stretched form; intestines — Nematode ×1, Acanthocephalan ×1; stomach wash — larval tapeworm ×1 (burrowed in tissues), Trematodes ×2. External surfaces and fins: no parasites. Stomach contents: zooplankton, few copepods.
Week 9 Fish Parasites — collection info, procedures
Findings — trematodes, nematode, acanthocephalan, larval tapeworm
