Banded Coral Shrimp
Stenopus hispidus · also called banded boxer shrimp
A fish hovers motionless above a reef crevice while a banded coral shrimp works over its skin and gills, long white antennae waving nearby as a mated pair defends the same cleaning station they have maintained together for as long as either has occupied it.
Overview
The banded coral shrimp, Stenopus hispidus, is a boldly patterned cleaner shrimp found on coral reefs across tropical and subtropical waters worldwide. Its striking red-and-white banding, dedicated cleaning-station behaviour, and genuine monogamous pair bonding make it one of the more visually and behaviourally distinctive small shrimp on any reef.
A cleaning business run by a permanent pair
Rather than working alone, the banded coral shrimp typically operates its cleaning station as a committed pair, defending the same small patch of reef together and offering a service fish return to again and again once they know exactly where to find it.
Status
Least Concern — widespread and common across suitable coral reef habitat in tropical and subtropical waters worldwide.
Banded Coral Shrimp: common questions
Why does the banded coral shrimp wave its antennae?
A banded coral shrimp waves its notably long, white antennae conspicuously to help attract the attention of fish passing by its established cleaning station, a visual signal advertising that the shrimp is available to remove parasites and dead tissue from any fish willing to stop and hold still.
What is a cleaning station, and how does the banded coral shrimp use one?
A cleaning station is a specific, fixed location on a reef where a banded coral shrimp waits for fish to visit and be cleaned, removing parasites, dead tissue, and mucus from the fish's body in exchange for an easy meal, a mutually beneficial arrangement that fish return to repeatedly once they learn its location.
Does the banded coral shrimp live alone or with a mate?
The banded coral shrimp is typically found living and defending its cleaning station territory as a monogamous mated pair, an unusually strong level of pair bonding for a shrimp, with both members working together to maintain and defend the same general site over time.
Where does the banded coral shrimp live?
The banded coral shrimp is found on coral reefs across tropical and subtropical waters worldwide, generally remaining at a fixed cleaning station location rather than ranging widely across the reef.
