Die
Remipedia zählen zu
den bemerkenswertesten zoologischen Neufunden der letzten 30 Jahre. Die
ersten Exemplare dieser Höhlenkrebse wurden 1979 während eines Tauch-gangs
in küstennahen Grotten auf den Bahamas entdeckt. Aufgrund ihres besonderen
Körperbaus wurde ihnen der Status einer Klasse innerhalb der Krebstiere (Crustacea)
zuerkannt.
Remipedien sind 8-45 mm lange, überraschend elegante und schnelle Schwimmer; ihre
Rumpfbeine sind als Ruderfüße ausgebildet und bewegen sich unablässig, auch
in Ruhephasen, in synchronen Zügen entlang der Körperachse. Als
Hermaphroditen sind Remipedien sowohl mit männlichen als auch mit weiblichen
Genitalien ausgestattet. Allerdings ist bis heute immer noch unbekannt, wie
sich diese Krebse fortpflanzen. Sie gelten als mögliche Urzeitform der Krebstiere. Anhand fossiler
Funde geht man davon aus, dass Vorläufer dieser Linie bereits vor 320
Millionen Jahren in den Meeren des Paläozoikums vorkamen.
Remipedia - a class apart
Remipedia
represent one of the most exciting zoological new discoveries in the past 30
years. The first individuals of these crustaceans were discovered in 1979
during a cave diving exploration on an island in the Bahamas. Because of
their unique body plan, the Remipedia are ranked as a class within the
Crustacea.
Remipedes are 8-45 mm long and surprisingly elegant and fast swimmers; their trunk limbs
serve as paddles that are constantly moving – even during rest periods - in
synchronous strokes along the body axis. As hermaphrodites they are equipped
with both male and female genitalia.
However, it is
not known to this day how remipedes reproduce.
They are believed to represent a
very ancient lineage of crustaceans.
Based on fossil evidence, it is assumed that the ancestors of this lineage
have inhabited Palaeozoic ocean basins some 320 million years ago. (More info about Remipedia at http://www.marinespecies.org/remipedia/index.php ). |

| Gattung/Genus:..Enyalioides | ||
| Herkunft/Origin:.. Peru | ||

|
The "woods" lizards exist on elevations below 2000m on both sides of the
Andes, between Panama and southeastern Brazil. These forest inhabitants are
very difficult to find due to the low density of their populations. They all
have robust heads and body, and usually have a prominent crest along the
back and the first portion of the tail and look like little dragons. Peru
currently has six known species of these iguanas. |

This
small, attractive frog belongs to the genus of reed frogs (Hyperolius) and
is known only from southern Rwanda so far. It reproduces in small ponds. The
species differs from its closest congeners genetically, bioacoustically and
morphologically. A special attribute of the species is its see-through
underparts. The internal organs and the bones are visible through the
transparent skin. |
