Record your own view first
Looking up an organism too soon can make a familiar picture seem to match a brief or partial sighting. A quick sketch gives you a record of the shape, proportions, and visible arrangement that caught your attention before an identification steers your memory. It does not need to be attractive or technically accomplished. Draw the overall outline, then add only details that were visible, such as a fringe, bands, a stalk, or the relative position of appendages. Mark hidden areas as unseen rather than filling them in from expectation.
Use the page to notice relationships
Drawing encourages you to compare parts with one another. Is the body longer than it is wide? Are the tentacles clustered at one end or spread around the margin? Does the animal attach to a surface or hang freely? Those relationships may be easier to preserve in a sketch than in a hurried string of adjectives. Add arrows and short labels for features that are difficult to draw. If exact size matters, include a scale or a measured reference, and note whether the organism was moving or distorted by a current. A sketch is a field record, not an anatomical reconstruction.
Keep the evidence and the lookup distinct
After sketching, add written observations and then consult a reliable reference suited to the organism group and region. Compare specific traits rather than asking only whether the whole drawing resembles a photograph. A sketch of a soft-bodied animal might preserve its outline but omit a tiny feature that separates similar groups; that limitation should remain visible in the note. Record candidate names in a separate “possible identification” line and say which traits support the match. If the illustration in a reference shows a feature that you could not see, do not silently add that feature to your field description.
Make a sketch useful later
Date and locate the sketch, identify its subject as tentatively as needed, and connect it to a photograph or notebook entry when available. Add orientation, a scale, and a few reference points if you plan to compare form across visits. For example, mark “viewed from above” and “approx. 2 cm across” rather than leaving later readers to infer angle and size from the drawing. If you revise your identification after research, add the new name and its basis without replacing the first record. The sketch then preserves both what you observed and how your understanding developed.
