The Robber (or Coconut) Crab, Birgus latro, is not only the world’s largest land invertebrate, it’s also a thief that climbs trees at night and steals coconuts!
These huge crustaceans of the south-west
Pacific and Indian Oceans, can grow to a length of 60 cm (2 ft), from
head to tail. They sneak out of their burrows at night, climb the
trunks of coconut palms or other fruit trees, and snip off the coconut
or fruit with their two giant pincers. They climb back down the tree
and gather up the food, then use the pincers to chip at the coconut
until it opens.

Some of the most fascinating instances of design are seen in symbiotic (‘living together’) relationships between different species, such as that which exists between goby fish and shrimp. They live together in a hole which is dug and maintained by the blind shrimp. The shrimp continuously keeps the entrance to the hole clear of debris by using its front claws in a bulldozer-like fashion, trusting the goby to keep guard at the entrance.
The shrimp always keeps one feeler (antenna) on the fish. If danger approaches in the form of a hungry predator, the goby signals the shrimp with a flick of its tail, and both scurry down the hole at lightning speed until the coast is clear.
Evolution has great difficulty explaining how such a partnership came about. This type of simultaneous programming points to creation.

Among the world’s smallest crustaceans are tiny creatures called water fleas (so named because they look much like those insects). The best known are of the genus Daphnia. Shown here is a Daphnia longispina.
The Horseshoe Crab is not a ‘true crab’ (it’s not a crustacean), but is rather another type of arthropod grouped with scorpions, spiders, and extinct trilobites. Here we have another example of what evolutionists term a ‘living fossil’. Fossil representatives almost identical to the modern-day Horseshoe Crabs date back to the Jurassic period (which supposedly started 190 million years ago).1 Again we see the claimed passage of vast amounts of time but without a hint of any evolutionary changes having taken place.
Horseshoe Crabs, once used by man mostly as fertilizer and as feed for chickens and hogs, are now highly valued for their contribution to medical science. Scientists recently discovered that the blood of the Horseshoe Crab contains a protein that is a key ingredient in a powder used to screen for contaminants in drugs, vaccines and intravenous drips.2 Scientists believe that no other creature produces the protein, and it can’t be manufactured by man. Interestingly, one-third of the Horseshoe Crab’s precious blood can be taken without causing death.3

Very little is known about the fairy crab, Lauriea siagiani (actually it’s a squat lobster). It was first described about eight years ago, discovered three years earlier in Bali, Indonesia. This fascinating creature appears to live only on the giant barrel sponge, along with some other tiny crabs of a different species.
