*Autumn Half Term Closure: 21st - 28th October 2026 Inclusive*
Sadly, due to the UK leaving the EU, we can no longer supply Northern Irish customers with any products the have codes starting with an 'L' or 'P'. This is due to the requirement for all live or preserved products to have an import licence specific to the customer purchasing and the product being purchased. As each licence takes 2 weeks to obtain, and involves a considerable amount of paperwork, we have made the difficult decision to stop offering these products to Northern Irish customers. We can still offer equipment, i.e. products with an 'E' code, as these simply require customs documentation.
We apologise for the inconvenience and if the legislation changes we will happily review our decision.
Delivery charges to the Isle of Man, Channel Islands (including Jersey & Guernsey), Shetland, Orkney and all the other islands we've missed, are the same as to mainland Britain (see above). The main difference is that delivery is likely to take a little longer, and for this reason we cannot guarantee next day delivery.
In addition, we cannot ship any liquids, so any 'wet' specimen ordered will be sent vacuum packed rather than in a jar.
Free delivery on orders over £75

Easy to navigate website & excellent service ~ the third or fourth time I’ve ordered from Darwin Biological and would happily use many more times 👍
Order was as expected. Delivery a little delayed due to summer closure of Darwin Biological.
growing really well and a lovely dark green
Excellent quality! Perfect from classroom demos - would definitely purchase again! Thank you so much!
These hearts arrive promptly and well packages. The hearts were entire ,with just enough tubes showing at the top.
Arrived on time, alive and active, Double bagged so no leakage. Worked well for the practical. The remainder were liberated humanly to nearby pond where they joined the circle of life as fish food.
