Captive Breeding Projects

Rhampholeon (R.) spinosus

 

For those interested in this species, I recommend reading Thomas Hildenhagen's article "East African Stump-Tailed Chameleons" on Chameleon News.  It is very helpful.

The photo to the right is of one of my breeding pairs on January 9th, 2009. The pair was kept together for only two days and then the male was placed back in his own enclosure. The female went from 3.1 to 3.5 grams and 3 months after breeding, she laid three fertile eggs on April 11th, 2009. The babies hatched out on August 2, 2009.

female spinosus Females tend to have a less spiney rostral appendage (rosette) and the anterior portion of their casque is shorter than a male's.  Their coloring is often lighter than a male's although at times they can become just as vibrant as a male.  They are often light tan, peach, or a muted green with some orange on their legs.  Sometimes they exhibit light blue on their casque but I've only noticed this during breeding or receptivity.

Another female with a stress pattern.  When under extreme stress the females turn black and white.  This is usually when they see a male and they are not immediately receptive.

First Captive Hatched ClutchCH#3

Beginning February 23, 2009 this clutch of 4 eggs took 103 days at temps ranging between 62 and 67.  Sweating occurred just before the egg was pipped.  Babies hatched each day by 10:00 a.m.

Hatchling #1:  February 23, started showing problems with coordination on February 28 and died on February 29.  I didn't find any evidence that it ate anything.  No poops.

Hatchling #2:  Hatched on February 24, showed no signs of trouble but died on February 29. No evidence that this neonate ate anything.

Egg #3:  February 25, began sweating, egg pipped, baby died without emerging. 

Hatchling #3:  Hatched on February 26, has been very active and eating fruit flies.  Photo to the right is of this chameleon. Beginning weight  0.1 gram.

 

Captive Bred Spinosus

CLUTCH FROM SPIN-F1 + SPIN-M1 BREEDING IN JANUARY 2009

SPIN-CB1 - Hatched 08/02/09; Eating and defecating

SPIN-CB2 - Hatched 08/02/09; Eating and defecating

SPIN-CB3 - Hatched 08/02/09; Not eating or defecating and becoming weak 08/24/09; Died 08/28/09

CLUTCH FROM SPIN-F2 + SPIN-M2 BREEDING DATE UNKNOWN

08/27/09 - Two eggs found in soil.  I missed this completely.  They look like they are about half way or almost through incubation.

CLUTCH FROM SPIN-F4 + SPIN-M4 BREEDING DATE UNKNOWN

08/16/09 - Laid three eggs

1 month .2 gram

1.5 months .3 gram

2 months .5 gram

Huge disappointment . .  . this baby died with no warning at the end of April. 

SPIN-F3

Weight increased over three months time until it reached 4.0 grams.

Early April her weight dropped .2 grams.  But on April 8th, 2009 her weight dropped even more and she weighed 3.2 grams.  Her terrarium was searched and three eggs found.  They went full term but the babies did not emerge.  They died in their eggs.

SPIN-F1Eggs in laying container

 

This is the type of egg laying medium provided to the spinosus.  The container is just a shallow food storage container intended for sandwiches.  A lot of holes are around the bottom outer edge.  Dwarf mondo grass is planted in the soil.  The soil is a mixture of organic orchid/violet soil and washed sand.

2:1 F1s hatched August 2008

The photo to the right is one of the Wieder's hatched out in August.  Out of the clutch of 7 eggs, 6 hatched with no problems.  The last egg had a fully formed dead baby.  Of the 6 hatchlings, 2 died within the first month.  To the right is a female and below is a male from the same clutch.

Offspring from the WC pair I acquired earlier this year.  This clutch started hatching August 19th and the last neonate emerged from its egg on August 25th.

A friend of mine had a clutch hatch out a couple of weeks earlier and I ended up buying his clutch.
