Alvinocarididae

**Alvinocarididae** là một họ tôm, được M. L.  Christoffersen mô tả lần đầu tiên vào năm 1986 từ các mẫu do tàu *DSV Alvin* thu thập, từ đó chúng có tên như vậy. Các loài tôm thuộc họ Alvinocarididae thường sống ở các vùng lỗ thông thủy nhiệt dưới biển sâu và môi trường rò rỉ hydrocarbon lạnh. Các sắc tố carotenoid được tìm thấy trong cơ thể những loài tôm này.
