Sea Lemon (Nudibranch)
Doris pseudoargus
Sea Lemons are nudibranchs, often yellow with darker blotches, feasting on sponges along rocky substrates. They lay distinctive coiled ribbons of eggs, which can be spotted attached to underwater surfaces. Around Lihou, if you carefully inspect shaded rock ledges in deeper pools, you may catch sight of one, slowly moving over sponges in search of its next meal.
- Habitat: Under rocks, on sponges, or near kelp holdfasts in shallow subtidal; occasionally in deeper rockpools.
- When to See: More likely in late spring/summer but can be found all year.
- Length: Can reach 10–12 cm
