A ichthyologist studying clownfish populations noted that the number of anemones supporting fish had decreased by 25% over the past year. If there were originally 160 anemones supporting 400 clownfish, how many clownfish per anemone are there now? - Crosslake

Ichthyologist Reports Significant Decline in Anemone Populations: Impact on Clownfish Numbers
A recent study by a leading ichthyologist reveals a concerning 25% decrease in anemone populations across a coral reef ecosystem—data that highlights growing challenges for one of the reef’s most iconic symbiotic relationships: clownfish and anemones. Over the past year, anemone numbers dropped by a quarter, from an original 160 to fewer today, drastically affecting the clownfish that depend on these spongy shelters for survival.
Originally, 400 clownfish thrived alongside 160 healthy anemones, allowing for an average of 2.5 clownfish per anemone. With the population decline, the number of anemones now stands at just 120—down 25% from 160. This sharp reduction has directly impacted the clownfish population, which needs stable anemone habitats to survive and reproduce.
Understanding the Context
New calculations show that only 3.33 clownfish now live per anemone on average, a dramatic shift from the original 2.5. This decline underscores how fragile reef ecosystems are and the ripple effects of environmental stress on species like clownfish.
The ichthyologist stresses that continued monitoring and conservation efforts are essential to prevent further declines and protect these fascinating marine partners. Understanding population dynamics like this helps guide science-based strategies to preserve biodiversity in coral reef habitats worldwide.
Key Takeaway:
After a 25% drop in anemone numbers—from 160 to 120—clownfish now average just 3.33 per anemone, down from 2.5. This significant shift highlights urgent ecological concerns affecting reef-dependent species.
