Mfundo
Its flesh contains a lethal poison, but its roe is a prized delicacy in Thailand, where it is served in a salad called yam khai maeng da.1
Horseshoe crabs have remained almost unchanged in shape and size for millions of years, and their fossils over 400 million years old look almost identical to living ones.1
Juveniles grow about 33% bigger each time they moult, taking about five moults to grow from 2 cm to adult size.1
Males cling to the backs of females for long periods before the eggs are laid, and it is thought that this species is monogamous.1
Horseshoe crabs have two compound eyes, which are mainly used to find a mate.1
