4) Marine sponge video
sampler
Time-lapse
speed: 1440 or 2880 x real time (1
second video time= 24 or 48 minutes real time)
Three species (in
sequence)
1) Aplysilla
longispina (leuconoid
architecture)
This was
collected from Beaufort NC. This
typical sponge undergoes several internal pulsations/contractions.
2) Leucosolenia
botryoides
(asconoid architecture) (2 clips) appeared in our tank and endured about eight
months of study before disappearing. These simpler tubes undergo slow locomotion and
contractions. From an upcoming
manuscript.
3) Sycon ciliatum (syconoid architecture) These
sponges are still living in our tanks.
Slow contractions are apparent.
To give an idea of
scale, the glassy spicules are all about 150 micrometers in length (100
micrometers= 0.1 millimeter).
