Umm, etymologists study words, etiologists study causation, and entomologists study bugs. You mean herpetologist I believe.

When they got a successful breeding at the FW Zoo, it was almost purely by accident. It was about 5 years ago now, so I can't remember the exact details.---Basically completely out of the controlled methology in zoo breeding.

quote:
the longtail tadpole shrimp is considered a living fossil because its basic prehistoric morphology has changed little in the last 70 million years, exactly matching their ancient fossils. Triops longicaudatus is one of the oldest animal species still in existence
The eggs are released in batches, have a thick shell, and can stand freezing temperatures as well as drought, enabling the population to survive from one season to the next. The eggs have to dry out completely before being submerged in water again in order to hatch successfully; they may remain in a state of diapause for up to 20 years. These eggs may have helped Triops longicaudatus, as well as other notostracans, to survive the various natural disasters and mass extinctions to date.
To complete their lives, tadpole shrimps depend on the changing nature of the temporary waters they inhabit. During the dry season (summer and fall), their offspring stay inside the eggs. As the pool fills with rainwater during the winter and spring, they hatch and feed on fairy shrimps and other invertebrates. The first larval stage (the metanauplius) is orange in color. It has a single eye, six legs, and develops through instars (growth stages). Each instar ends with shedding the exoskeleton. The number of segments and appendages increases as Triops grow, and they slowly change to greyish-brown. In approximately eight days, they reach maturity and lay eggs. Adult Triops die as the pools dry up. Triops generally live for about 20–90 days if the pool does not dry up."
