The pellets were well packaged and arrived very quickly.
During dissection we found a large quantity of bones from lots of different animals and students really enjoyed matching them to our guide leaflets.
A great practical and would very much recommend.

An excellent product. Well made and definitely not a toy!

Two items ordered, they came ultra fast and both are perfect, exactly what I was looking for and very reasonably priced.

Excellent product. Loads of bones in these pellets. Really easy for children to dissect. Fantastic for my Science lessons

Arrived frozen and with plenty of warning so we could catch the post before it disappeared into the internal system.
A good selection of reasonably sized fish heads, I was sceptical with a weight rather than head count in the description. We will definitely buy again.

Order arrived very quickly, the next day, in fact. Plenty of Drosopila in culture and have now split them. Have them as food source for newly hatched day geckos.

Always prompt with delivery and they have always been in stock. Well packaged quality products and an easy order process.

Perfect items with quick delivery.

Ordered several preserved specimens (sheep brain, heart, eyes and a squid) that all arrived quickly. Specimens are high quality and will be great resources for my class. I will definitely be back when I need more biological supplies.

Great product. Maggots arrived alive and healthy.

My algae is growing fabulously. Instant delivery, amazing service!

Arrived on time- as always, and great condition. One happy don.

This is the second time that we have ordered from Darwin Biological. The materials provided are of high quality, just what we have needed for our medical ultrasound training. Their staff are conscientious and careful, ensuring that the materials arrive in the best possible condition. They are easy to communicate with and have been very responsive.

Quality products, and fast, friendly service. Always trust Darwin Biological with our classroom supplies.

Amazing service :). A couple of weeks ago I tried to order some maggots of the species Calliphora vomitoria from another website and they canceled my order. So then i found out about this company “Darwin Biological” and they’re the best maggots i’ve seen in my life. I chose the next day delivery option, arrived in time, and the little ones were all alive. Amazing service !!!
