Velvet Swimming Crab
Necora puber
Velvet Swimming Crabs have bright red eyes and a velvety texture on their shell, which gives them their common name. They can be aggressive, raising their pincers and moving sideways at surprising speed if disturbed. Around Lihou, lift a rock or look in a kelp-covered pool at low tide and you may catch a glimpse of one, scuttling quickly to safety.
- Habitat: Rocky areas from mid to lower shore, preferring crevices and undersea weed cover.
- When to See: Mostly seen at low tide. Active in warmer months.
- Length: Carapace up to ~9 cm across
