1. Hermit crabs

2. Introduction
• Related more closely
to lobsters rather than
crabs
– Lack of hard
carapace.
– adopt the empty
shells of
gastropod
molluscs (such as
whelks), carrying
them around and
swapping them
for a larger shell
as they grow

3. • When seen out of a shell, hermit crabs
have a bizarre appearance;
– the soft abdomen is twisted, which
allows it to fit into the coils of the
gastropod shell.

4. Distribution
• worldwide in distribution,
– occur in sandy- or muddy-bottomed marine
waters
– occasionally on land and in trees

5. SHAPE AND APPEARANCE

6. • Color:
– The common hermit crab is
typically reddish or brownish in
color.

7. • Abdominal appendages on the female carry
the eggs, which are held there until they
hatch; the young pass into the water as
swimming larvae.

8. • appearance:
– has two pincers on the first
pair of walking legs.
– The soft abdomen is
asymmetrical, usually
curling to the right. There
are two pairs of antennae
and five pairs of legs

9. Biomimicry
• As the crab grows and becomes too large for its
shell, it must find and move into a larger one.
• The availability of suitable shells is often limited, so
competition among hermit crabs for shells of the
proper size and in good condition is intense.

11. Habitat
• Some hermit crabs live in:
– the tubes of plant stems.
– Semiterrestrial,
– tropical species of
Coenobita inhabit sections
of bamboo stems,
– broken coconut shells, and
other articles,
– seashells.
