1 Tunicates

2 Botrylloides violaceous Orange, red, pink, or yellow sheet Solid color, very little tunic between zooids Large zooids, openings obvious

3 Botryllus schlosseri Star shapes arrangement of zooids Often black & white, but can be orange

4 Botrylloides v. Botryllus Orange morph of Botryllus rare, but, star-shape is the giveaway! Botrylloides can have looser zooid structure

5 Ciona intestinalis Red dot at end of intestine Clear solitary No color on siphons Yellow band or clear at tips of siphons

6 Ciona savingyi Spots of color at tips of siphons No red dot at end of intestine

7 Which is which?

8 Ascidiella aspersa Firm transparent test, snags detritus Tentacles in siphons Elongate oval

9 Molgula manhattansis Sea grape – small, round, like a peeled grape Ascidiella is elongate and opaque in comparison

10 Molgula citrina More color than M. manhattensis Potentially more fouled tunic

11 Dendrodoa carnea Small (<2cm), pink Squashed looking Small stubby round siphons

12 Halocynthia pyriformis Sea peach Larger (up to 10cm) Siphons almost square

13 Aplidium pallidum Sea pork - because it looks like a hunk of lard White & clear Occurs in chunks

14 Didemnum vexillum Think drippy sheet Pendulous lobes common Peeling away from rock Yellow-ish white

15 Didemnum vexillum Solid sheet, speckled with zooids & oscula Typically very thick

16 Didemnum albidum Solid white sheet VERY tight zooids Some oscula Thin & smooth

17 Diplosoma listerianum Thin diaphanous sheet Can be greyish and/or yellowish Like an odd plastic sheet Can have conspicuous oscula

18 Styela Clava Tunicate on a stalk! Large rough pleated body Curved siphon Can be found in the frozen section of Hmart

19 Styela Clava

20 Boltenia ovifera Stalked tunicate Round zooid, like a lollipop Smooth Typically deep-water

21 Boltenia echinata Stalked tunicate Cactus-like with many spiky projections Short stalk Rare

22 The Stalked Ones

23 Bryozoans

24 Bugula turrita Like a colony of Christmas trees

25 Bugula fulva Similar to B. neritina, but white/yellowish Distinctive forking branches

26 Bugula neritina Purple

27 Tricellaria inopinata Short dense tufts Heavily calcified – crunchy to the touch

28 Crisia eburnea Very fine Spindly, feathery Bugula is much more solid Not always very regular

29 Dendrobeania murrayana Small fans Thick lattice Like a lace tree

30 Electra pilosa Encrusting stars

31 Membranipora membranacea White crust Amorphous Fouling on algae Blocky zooids give delicate appearance

32 Lichenopora verrucaria White Often circular growth Thicker in center, like luchen On hard substrate Lichenopora

33 Schizoporella unicornis Bumpy thick crust Mix of orange and white Amorphous, on rocky substrate Zooids like open pores

34 Schizomavella auriculata Bumpy thick crust JUST orange/orange cream soda Amorphous, on rocky substrate

35 Sponges

36 Cliona sp. Bright yellow Often boring into something rocky Large oscula

37 Hymedesmia sp. 1 Blue

38 Hymedesmia sp. 1 Orange Sheet

39 Halisarca dujardini SLIMY!!!

40 Leucosolenia sp. Many Tubes

41 Scypha sp. Small tubes Vase-like

42 Isodictya palmata Palmate Orange palms, not so branching Can have conspicuous oscula

43 Haliclona oculata Cream-Orange Branching fingers

44 Microciona prolifera MANY red fingers

45 Halichondria panicea MANY forms Often oscula obvious Texture of bread crumbs when broken apart

46 Hydroids

47 Abietinaria abietina Coarsely branching

48 Sertularia sp. Finer feathery branching

49 Ectopleura crocea Pink rosette tips, like flowers

50 Obelia spp. Fine and frilly Lace-like covering Often epiphytic

51 Anemones

52 Cerianthus borealis In sandy areas Sand-tube around body Long distinct arms

53 Diadumene lineata Body has lines Often quite small

54 Metridium senile Body can be yellow or white Frilly plumulose arms Often very large

55 Urticina felina Multicolored banded arms Many colors possible

56 Fagesia lineata

57 Molluscs

58 Modilus modiolus v. Mytilus edulis ModiolusMytlius Flat & Brown-redPointed & Blue-Grey
