There are four major types of injury patterns from marine life.

Page 3: Dangerous marine creatures

AnemoneCOMMON HABITAT: All Hawaiian waters from tide pools to deep offshore waters.

PREVENTION:Avoid direct contact with skin. While tide pooling use footwear and don't put fingers/hands into holes and crevices.

INJURY MECHANISM: Tentacles have stinging cells that are used for catching prey.

SIGNS AND SYMPTOMS: Burning and itching sensation, redness and swelling where contact was made. Severe Reaction: may include shortness of breath; loss of consciousness.

FIRST AID TREATMENT: Rinse thoroughly with fresh or salt water. Apply ice for pain. IMMEDIATE medical attention may be required for severe reactions.

Page 4: Dangerous marine creatures

                           

COMMON HABITATOpen waters/bay areas in the

shadows, under floating objects.

PREVENTIONDon't wear shiny objects. They are

attracted to reflective things that look like dinner.

INJURY MECHANISMSharp jagged teeth with strong

tearing jaws.

SIGNS AND SYMPTOMSSlashed and jagged tears in your

skin.

FIRST AID TREATMENT Stop Get medical help.

Barracuda

Page 5: Dangerous marine creatures

                      

COMMON HABITATTide pools, sandy areas, shallow to

deep offshore waters.

PREVENTIONDo not handle (even with gloves),

especially near tip.

INJURY MECHANISMPoisonous, dart-like mechanism near tip used for stunning and killing fish and invertebrates.

SIGNS AND SYMPTOMSStinging, burning pain, numbness,

coma or cardiac arrest.

FIRST AID TREATMENTScrub the wound. Get medical

help for severe reactions.

Cone Shell

Page 6: Dangerous marine creatures

COMMON HABITAT: Very common in all water bodies. Box jellyfish regularly swarm to Hawaii's Leeward shores 9 to 10 days after the full moon. Carybdea alata cause the most "trouble" for humans in Hawai`i.

PREVENTION: Don't go into areas where sighted, or if dead ones are seen on the beach. Observe posted signs.

INJURY MECHANISM: Stinging tentacles.

SIGNS AND SYMPTOMS: Stinging, burning, redness, swelling of lymph nodes. Severe reaction: difficulty with breathing and cardiac arrest. Occasional long welt lines.

FIRST AID TREATMENT: Douse with vinegar. Apply ice for pain. IMMEDIATE medical attention may be required for severe reactions.

Box Jellyfish

Page 7: Dangerous marine creatures

                      Moray eel

COMMON HABITATRocky areas, in holes, under rocks, crevices and tide pool

ledges.

PREVENTION

Keep hands out of rocky areas, holes and crevices. Use stick to probe. Dead fish, blood or bait

will bring them out of their holes.

INJURY MECHANISM Razor sharp teeth, powerful jaws.

SIGNS AND SYMPTOMSBleeding, severe muscle

damage, but more commonly tendon and nerve damage.

FIRST AID TREATMENTStop bleeding with pressure,

clean thoroughly. Get medical help (guard against infection).

Page 8: Dangerous marine creatures

                      Needle fish

Near surface in bay areas and open waters.

PREVENTION Use caution when night lighting/fishing.

INJURY MECHANISM Long pointed jaw.

SIGNS AND SYMPTOMSPointed jaw may puncture and break off

leaving a puncture wound.

FIRST AID TREATMENT

If point doesn't break off, clean with antiseptic if stabbed. If point breaks off do

not remove it. Stop any bleeding with pressure. Get medical help immediately!

                                

COMMON HABITAT

Page 9: Dangerous marine creatures

      

Portuguese Man-O-War Jellyfish

Open ocean. Bays and beaches during strong onshore winds.

PREVENTIONAvoid areas where they frequent. Usually

found when winds blow in from the ocean onto land. Observe posted signs.

INJURY MECHANISM Long blue, threadlike tentacles.

SIGNS AND SYMPTOMSStinging, burning, redness, swelling of lymph

nodes. Severe reaction: difficulty with breathing and cardiac arrest. Long welt lines.

FIRST AID TREATMENT

Pick off any visible tentacles. Rinse with fresh or salt water. Apply ice for pain. IMMEDIATE

medical attention may be required for severe reactions.

COMMON HABITAT

Scorpion Fish

COMMON HABITATProtected ledges, rocky areas, and

shallow inshore areas.

PREVENTIONDo not handle. Keep out of crevices and places into which you can't see.

INJURY MECHANISM Toxic dorsal, pelvic, and anal spines.

SIGNS AND SYMPTOMS

Punctured skin, extreme pain, throbbing for hours. Sometimes

convulsions and cardiac arrest; but rarely, in Hawai`i, such very serious

reactions.

FIRST AID TREATMENT

Immerse in hot water to tolerance. Get medical help for serious

reactions or for infection.

                      Sea Urchin

COMMON HABITATShallow reef areas to 100 foot

depths.

PREVENTIONWear foot protection. Don't walk

on rocky areas with poor visibility. Do not handle!

INJURY MECHANISM Long, extremely brittle spines.

SIGNS AND SYMPTOMSThrobbing pain. Purplish

discoloration.

FIRST AID TREATMENT

Pull out protruding spines. If spines(s) is/are in a joint, nerve, or when wound is

infected - get medical help.

Page 12: Dangerous marine creatures

                            Sharks

Shallow inshore waters to open ocean.

PREVENTION

Avoid murky waters. Leave water if sighted, if you have an open cut or are pulling a string of speared

fish. Try not to look like food.

INJURY MECHANISMJaws and rows of razor sharp

teeth. Abrasions from sandpaper-like skin.

SIGNS AND SYMPTOMSSevere bleeding, injury to or excision of muscle, bone and

appendages.

FIRST AID TREATMENT

Control bleeding with pressure. Transport to medical facility or call 911 for an ambulance for

severe shark attack bites.

COMMON HABITAT

Page 13: Dangerous marine creatures

                      

Stingray

Shallow, sandy areas to deep oceans.

PREVENTIONShuffle feet when walking in shallow

inshore waters. Stay clear of disturbed (swimming) ray. Do Not Molest!

INJURY MECHANISMTail with poisonous barb near base of

body.

SIGNS AND SYMPTOMSLacerations and severe pain. Punctures in abdomen or chest are very serious - a

medical emergency.

FIRST AID TREATMENT

Stop any bleeding, clean thoroughly with mild soap and water. Immerse in hot

water to tolerance for pain. Get medical treatment for deep cuts and embedded

barb pieces. Do not try to remove pieces yourself - get medical help.

COMMON HABITAT

                      Surgeonfish

COMMON HABITAT Wave zone to 150 foot depths.

PREVENTION Take care in handling.

INJURY MECHANISMSpine and knife-like razors near

tail.

SIGNS AND SYMPTOMSThrobbing pain, itching, bleeding

and numbness.

FIRST AID TREATMENT

Stop bleeding with pressure, clean thoroughly with soap and water.

                      Tube Worm

COMMON HABITAT Shallow reef areas.

PREVENTIONUse protective footwear and

gloves.

worm's shelter.

SIGNS AND SYMPTOMSCircular cut with fragments that may be embedded. Bleeding.

FIRST AID TREATMENT

Stop bleeding with pressure, clean thoroughly with soap and water.

Get medical treatment for deep cuts and embedded pieces. Do

not try to remove pieces yourself.

Box jellyfish have been known to kill people within three minutes, blue-ringed octopus in 30 minutes and pufferfish (eaten) in 17 minutes. You are more likely to die from a box jellyfish sting than a shark attack. Reef sharks are not normally aggressive to humans but should be treated with respect. Do not carry bleeding fish and avoid swimming after dark.
