The Negev Tortoise project continues steadly.

The two babies born last year are getting bigger and remain behind-the-scenes in the Small Animal House.

The good news is that already we have two eggs in the incubators and we look forward to seeing them successful hatch in the near future.

In the wild, most egg laying activity would take place in spring or early summer, to allow the hatchlings to grow a little before their first hibernation.  There is, however, no set breeding season for the majority of tortoises in captivity and egg production can take place at any time of year.

It is common for tortoises to lay more than 1 clutch of eggs in the year, and the number of eggs laid does vary with different species of tortoise, but as a general guide, the average clutch size will be between 2 and 12 eggs. 

The incubation period of tortoise eggs is quite long in most species, the average incubation period are between 100 and 160 days.

We will keep you updated on their progress.

Stay healthy!

The two new baby tortoises that hatched this past spring are growing up fast.

They are still hanging out behind the scenes in the Small Animal House.

One of the interesting things that the keepers have learned this past year is about the impact of the tortoises' diet on the appearance of their carapaces.

In the picture below, you will see the difference between the tortoise raised in the Zoo (with the raised bumps on its carapace) and the tortoise that was rescued and had her carapace repaired, who grew uo outside the Zoo (her carapace is smoother.)

The keepers found that the tortoises who had been raised on lettuce had these bumpy shells and have since changed the tortoises diets from lettuce (which is not native to the Negev Desert, of course) to a local plant to the region: mallow

The mallow is an annual plant that reaches a height of some 50 cm (20 inches). It blossoms from February to June, and has pink, five-petaled leaves, approximately 2.5 cm (about one inch) in diameter. Mallow, whose modern Hebrew name, halamit, is almost identical to the biblical halamot (mentioned in Job 6:6 for example). The Arabic name for the plant is hubeza, which it is commonly. Israel is home to six species of the plant.

A new addition to the Tortoise enclosure is causing a stir!

An injured female Negev Desert Tortoise was brought into the Zoo clinic suffering from a broken carapace (the top or dorsal shell).

The Zoo vets fixed the crack and after healing, she was introduced to the enclosure.

Up until now, the enclosure contained six males and two females and thus the appearance of a new young female was welcomed enthusiastically by the males.

We are now looking forward to see the results of this enthusiasm and hoping for some new additions in the coming months.

This past season concluded with three baby tortoises hatching and two surviving.

They are currently maturing behind the scenes in the Small Animal House at the Zoo.

Have a safe winter,

Dear Tortoise Supporters, 

I just came back from a visit to the Small Animal Enclosure at the Zoo, where I went to visit the latest "baby" born last week.

Still un-named, the tiny baby tortoise (pictured during its hatching) is being kept behind-the-scenes in a small terranium until it is big enough to join its cousins and uncles and aunties in the main exhibition. 

This cutie is the third tortoise hatched this season and according to Tal, the small animals keeper, there is lots of dating and mating going on and they hope to have another round of hatchings in the coming months.

Slowly but surely, we are making a difference to the numbers of this critically endangered species!

Have a safe summer!

Dear Desert Tortoise Supporters,

Since we last reported to you, of the 6 eggs which were produced by our breeding group and placed in incubation,  3 were fertile and so far 2 have hatched!  A small victory for the conservation of this critically endangered species. The offspring will join their family within their exhibit and we hope in time to produce more.

Captive breeding for desert tortoises requires greater care than in other tortoise species, as the species is more delicate and the clutch is very small. Fortunately, we have a very experienced zoological team who are doing their best for these, the smallest species of tortoise in the northern hemisphere.

Yours, in hope -

Team Tortoise at the Jerusalem Biblical Zoo
