Hybridization Ledas to Pollution Tolerance in Fish in Heavily Polluted Houston Ship Channel (3 of 3)

Caption

Five-day-old Gulf killifish embryos from two different populations in Galveston Bay, following exposure to environmental pollutant. The heart in the one on the left, from a reference site, has failed to properly develop, which has dramatically reduced its growth and will ultimately prove fatal. Meanwhile, the one on the right -- from the pollution-tolerant population in the Houston Ship Channel -- is developing normally in spite of chemical exposure.
