Haeckel - Challenger Siphonophores
Haeckel was invited to analyse the samples and prepare the report for four
groups of organisms collected during the HMS Challenger Expedition.
His report on the Siphonophores is in Volume 28 of the report (
Report of the Scientific Results of the Voyage
Of H.M.S. Challenger during the years
1873-76).
This contains 50 images of
siphonophores, plus apparently 9
woodcuts (I’ve never been able to locate the latter, but they may be embedded in
the text). The plates are available
at two sites – the Bossard site is the most accessible; the images on our site
have been downloaded from the Heritage Library site, as they are of better
quality.
The following
description of the Siphonophores is downloaded from a spectacular site on these
organisms created and maintained by Dr Casey Dunn of Brown University in Rhode
Island
“
Siphonophores
belong to the Cnidaria, a group of animals that includes the corals, hydroids,
and true jellyfish. There are about 175
described species. Some siphonophores are
the longest animals in the world, and specimens as long as 40 meters have been
found. The majority of siphonophores are
long and thin, consisting mostly of a clear gelatinous material.
Some deep water species have dark orange
or red digestive systems that can be seen inside their transparent tissues.
Siphonophores are exceedingly fragile and
break into many pieces under even the slightest forces.
Many siphonophores are bioluminescent,
glowing green or blue when disturbed. All siphonophores are predators, and use
their many tentacles to capture crustaceans and small fish
.”
Probably the best know
Siphonophore is the
Portuguese
Man o War
(
Physalia
physalis
). Its venomous
tentacles can deliver a powerful sting.
