Medicinal Leech

The Medicinal Leech (Hirudo verbenaand Hirudo medicinalis) is an invertebrate parasitic worm, and an annelid. It is related to the earthworm. It is called medicinal because doctors have used the leech to draw blood from patients.

There are two types of true leeches: Rhynchobdellida (with a proboscis to puncture the skin of animals) and Arhynchobdellida (without a proboscis). The Medicinal Leech (Hirudo verbena) is a Arhynchobdellida Hirudiniformes (a leech without a proboscis, but with jaws at the front of the mouth).

The Medicinal Leech has a flat, soft, muscular, segmented body without a backbone or skeleton. Therefore, it is an invertebrate. Its upper part is grey with pinkish stripes, or  mottled grey-pink-brown, and its underbelly is pale-grey. Its body can lengthen and contract (i.e. get bigger and smaller) as it moves. It has suckers on it mouth and its tail end (anterior and posterior suckers).

Common Marine Hermit Crab

The Common Marine Hermit Crab (Pagurus bernhardus) is a saltwater aquatic decapod (10-armed) crustacean. It is also known as the Soldier Crab.

Hermit crabs include the Marine Hermit Crab, which lives in saltwater, and the Land Hermit Crab, which is terrestrial in tropical regions.

The Common Marine Hermit Crab is a crab inside a shell – its mobile home. It finds empty mollusc shells to live in. It has a long soft body – not like land crabs which have a hard exo-skeleton – which is why it looks for a hard shell to protect it. It can put its whole body inside the shell. As it grows, it looks for larger shells.

The Common Marine Hermit Crab has a spirally-curved soft body (abdomen) with a columella on the tip, which is used to hold onto the shell it occupies. It has 10 appendages (legs, called pereiopods), but two of them are claws, called nippers, pinchers, or chelipeds. Its large black compound eyes are at the end of an eyestalk. It has gills to breathe (like fish).
