Biology     Glossary (e.g. epibenthic)

Adults inhabit coral reefs (Ref. 9710), from clear coastal to outer reef walls, usually where currents are moderate (Ref. 48636). They swim 2 to 3 m above the benthos, feeding on plankton (Ref. 94105). During the orange-yellow phase, they are observed to school with Pseudanthias squamipinnis which they resemble in color. Individuals of Ecsenius midas can change color quickly from when on the bottom to swimming in open water to match the colors of the fishes they mix with (Ref. 48636). They also socially mimic their swimming behavior and also of Pseudanthias huchtii and Lepidozygus tapeinosomoa (Ref. 90102). Reported to feed on zooplankton (Ref. 37816). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Minimum depth reported taken from Ref. 9710.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00322 - 0.01632), b=3.00 (2.80 - 3.20), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.6   ±0.29 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
