Arthropod Characteristics –More than 1 million species known, mostly marine –Most marine species are subphylum Crustacea (shrimp, lobster, crab, barnacles, etc) Coral crustaceans Coral crustaceans Coral crustaceans Coral crustaceans California crustaceans California crustaceans California crustaceans California crustaceans –About 75% of all animals on earth are arthropods –Chitin exoskeleton - hard, but light and moderately flexible –Must molt to grow (Video: molting) molting

Arthropod Characteristics –Jointed appendages –Many divided into sections called head, thorax and abdomen –Specialized segmentation- segments combined for specific functions –Simple brain but specialized eye & sensory organs –Specialized respiratory structures, gills, used for gas exchange –Some are filter feeders, some scavengers, others carnivores filter feeders carnivoresfilter feeders carnivores

Arthropod Reproduction –Male transfers sperm directly to female to ensure reproductive success –In some species, female will house eggs for a time until they are further developed –Females can store sperm for fertilization at a later time –Many arthropods have complex behaviors including mating rituals (lobsters); mating rituals (crabs) mating ritualsmating ritualsmating ritualsmating rituals –Baby Crabs Baby CrabsBaby Crabs

Planktonic larvae to Adult organism

Subphylum Crustacea –68,000 species –2 pairs antennae –Gills for respiration –Head and thorax fused into a single unit called a cephalothorax; entire external body is called the carapace –Large array of appendages specialized for different functions; ex: pinchers on crabs, swimmerettes on the underside of shrimp hold developing eggs, etc. –Types of crustaceans – copepods, barnacles, amphipods, isopods, crabs, shrimp, lobsters, etc. lobsters

Isopod Ligia oceanica – sea louse First antennae – Specialized for swimming Copeopod Amphipod Orchestoidea – beach hopper Curved and flattened sideways, ~2cm. Dorsoventrally flattened, commonly parasites, ~2cm. Planktonic, extremely abundant.

Barnacles Cirri are modified legs Reproduction

Decopods Largest group of crustaceans with ~10,000 species Largest group of crustaceans with ~10,000 species Largest crustaceans Largest crustaceans 10 legs 10 legs Shrimp, lobster, and crabs Shrimp, lobster, and crabs Carcinus maenas

American Lobster Homarus americanus

Caribbean Spiny Lobster Panulirus argus

Class Merostomata Horseshoe crabs- Horseshoe crabs- Horseshoe crabs Horseshoe crabs –5 pairs of legs, first pair modified in males for reproduction –Females larger than males –Mating pairs come onto beaches each spring to breed and lay their eggs in wet sand –Among the oldest creatures on earth – they have remained virtually unchanged for millions of years –They live and borrow in soft sediments, normally near shore where they feed on other invertebrates and scavenge. –Valuable blood Valuable bloodValuable blood

Class Pycnogonida Sea Spiders: Sea Spiders: –Four of more pairs of jointed legs –Not insects or true spiders –Possess a mouth and proboscis for feeding –Mainly feed on sea anemones and hydrozoans (they are voracious predators!) –More common in cold waters, but can be found worldwide

Sea spiders Sea spiders

Class Insecta Insects: Insects: –Very few marine insects exist –Many insects feed in the intertidal zone at low tide, but these are just temporary visitors
