Resumo(s)
The embryonic and larval development of the pipefish Syngnathus abaster is described, based
on ex situ observations. The full development sequence lasted 24–32 days (at 18–19 C), which
was shortened to 21 days at higher temperatures (21–22 C). Newborn juveniles, with a uniform
dark brown colouration, immediately assumed a benthic spatial distribution. This vertical
distribution pattern remained unchanged at least during the first 4 weeks, after the release
from the marsupium. The apparent absence of a pelagic life phase might have important
repercussions in terms of population connectivity given increasing fragmentation and degradation
of the eelgrass habitat in the species’ range.
