Lysmata boggessi larva


This is Lysmata boggessi,one of the new described species of the former wurdemanni/rathbunae complex.
This peppermint can be recognized by the pale body and dark tail,without the red saddle marks.It seems to be common in LFS of the Miami area.
See the colour of the eggs,so different to the light green of other Lysmata.
This is a newly hatched larva,zoea1:
Sessile eyes
One piece tail fin
one pair of walking legs and two pairs of swimming legs.
Compare with the z1 of L.amboinensis at http://reefcentral.com/forums/showth...hreadid=846955

Nice. First time I have heard of Lysmata boggessi. At first glance I thought it was a L. vittata. So many species that look so alike! Maybe a good way to differenciate them is to see how their larvae look like?

Zoea 2


This is zoea 2,two dah,3.13mm.Stalked eyes,no other major changes.
This species molts and changes stages every two days.Under the same conditions L.amboinensis takes 3-4 days and S.hispidus 6 days.
This reflects the long larval phase of these two shrimps,which can be further prolonged by "marking time"(molting without changing stages).
Conversely,one can expect that boggessi has a very short and easier (for the aquarist) larval phase.

Interesting. What temperature are you raising the little guys at? I'm going to try 31 & 34 degrees on a new batch of amboinensis. Probably guess they won't take it very well but you'll never know.

Any special reason for keeping the temp. that low?

Zoea 3


This is zoea3,at 6 dah and 3.5mm.
The telson is now separated from the uropods.The outer is colored and the inner is clear and smaller but still can be seen in the pic.
Walking legs are two pairs (mp3 and pp1).Swimming legs are three pairs (mp2,m3 and pp1).I was lucky to catch them in focus,they are moved fast continuously.They are clear and delicate and show long setae (hairs) that assist to swimming.
Here are two more:


There is something amazing;these larvae are now virtually identical to L.amboinensis of the same age,see :http://reefcentral.com/forums/showth...hreadid=846955
and they were very different at Zoea 1.
Steve sustained that peppers and cleaners are not very related and the early stage points in that direction.But Z3 now show they´re close of kin.
Though later,as said before,cleaner´s larvae will again be very different to those of peppers.
It is a pain for those wanting to understand their evolution by looking at the larval development!
