A cosmetic variant of the creature can be found in the **Necrolei Hills**, which shares the same databank entry but is predominantly blue in color.   ![Orange Variant](Periscopic Clowncrab Render.png) ![Blue Variant](Periscopic Clowncrab Necrolei Hills Render.png)   ## Behavior   Periscopic Clowncrabs can be seen wandering around the seafloor in the Coral Gardens region, usually looming in dense patches of anemones that match their body color. They can be found alone, as well as in small groups. The Clowncrabs are passive and curious, and will stare at the Player if they are approached.  -## Databank+## Databank Entry  -**Periscopic Clowncrab**- -*Ostrakonskelos periskopion*, the hard-legged periscope. A social crab that shelters among stinging anemones.- -1. **Reduced body**: The clowncrab's single-segment body is an illusion. The multiple segments of other Protean arthropods are still present, nested inside. When the clowncrab molts, it sheds its internal shells through its digestive tract.-2. **Regenerative eyestalk**: Enormous eyestalks mimic the surrounding raions. If bitten off by a predator, each stalk is packed with unspecialized cells that quickly regenerate missing eyes. If the stalks grow too long, the clowncrab will trim them to avoid drawing attention.-3. **Raion tender**: The clowncrab provides a valuable service to sessile raions by ranging out to forage, returning nutrients in its molt and waste. It also grooms the raions to clean parasites and infections.-4. **Fecund stalk**: The third stalk behind the eyes is a reproductive organ. The same unspecialized cells used to heal the eyestalks become eggs or sperm. Sperm is released into the seawater, while eggs are deposited among raions.- -**Assessment**: sign of a healthy raion field.- -> *Caught script hook in allocated memory for command >> generate-databank "Clowncrab" >> echo \memory-carve -signature=0xSEABEEF5 >> restore-remarks*+> **Ostrakonskelos periskopion**, the hard-legged periscope.
