LOUISIANA WATER & WILDLIFE

Louisiana wildlifeand water habitats.

Explore the animals in and around Louisiana’s water, from fish and shellfish to dolphins, turtles and birds. Look up a name, learn about the habitat or choose a guide to watching wildlife, paddling or collecting shellfish.

UNDERSTAND WHAT YOU ARE SEEING

Start with the animal group and visible features.

A fin at the surface is a clue, not a complete identification. Fish breathe through gills; dolphins and whales are air-breathing mammals. Turtles and alligators are reptiles, and sea turtles also surface for air. Look at body shape, markings and movement together rather than naming an animal from one feature.

If the view is brief, record the place, time and what you actually saw. “A dark animal swimming beside the bank” leaves the identification open until you can compare useful features. The wildlife-watching guides explain what to notice without approaching or handling the animal.

A habitat is the kind of place an animal lives. Search a known name in the notes below, or browse the collections for a fuller introduction. A short note may link to a related subject rather than a guide devoted to that exact animal. The illustrations introduce animal types; they are not complete identification references.

103 SHORT NOTES · LOUISIANA & THE GULF

Meet the animals in and around the water

Try an animal name, or browse by group and water type. Fish, mammals, reptiles and shellfish are different kinds of animals; the notes help you start learning which is which.

103 of 103 entries match. Showing 12.

Habitat means the place an animal lives. Water tags describe broad settings, not today’s location of an animal. Some notes cover a group of animals, marked as a group entry. The illustrations introduce animal types; use a full reference for identification. In fin descriptions, dorsal means along the back, pectoral means at the sides behind the head, and anal means on the underside toward the tail.

Sharks

Blacktip shark

Carcharhinus limbatus

Historical Louisiana survey

A coastal shark associated with bays, river mouths and shelf water. It can resemble a spinner shark, so compare fins and body together.

A starting point

Black-tipped fins can resemble spinner shark; compare the underside fin near the tail and the position of the first back fin.

Turtles, alligators & snakes

Kemp’s ridley sea turtle

Sources and review notes

Our field notes synthesize the references below. Some surveys and biology accounts are historical. Louisiana records are distinguished from the wider Gulf range; existing fishing lessons keep their original source and review notes.

Louisiana Department of Wildlife and Fisheries
Louisiana fish-identification posters, waterbody management plans, the shrimp-fishery bycatch evaluation, wildlife action plan and mussel accounts support local occurrence and animal names. Some official pages were available only as indexed text; direct requests returned access errors.
Louisiana Sea Grant, LSU AgCenter and the University of New Orleans
Sea Grant biological profiles, the 2006 Louisiana shark-nursery study summary, crawfish biology and the 2025 Pontchartrain invertebrate guide inform habitat and identification notes. Historical survey records describe past observations rather than present abundance.
NOAA Fisheries and the U.S. Fish and Wildlife Service
Species profiles, shark-identification references, the Louisiana protected-marine-species list, refuge accounts and the Louisiana pearlshell account inform biology and range. NOAA’s 2026 whale-shark report qualifies the historical Ewing Bank aggregation.
Additional identification comparisons
Texas Parks and Wildlife species profiles inform anatomical comparisons, with Louisiana occurrence checked separately. Texas fishing rules and access information are not applied here. The mammal lessons also retain their attributed Virginia Tech identification comparison.

Recognition cues and illustrations are starting points, rather than complete identification keys. Our Louisiana licenses and rules guide explains how to use the responsible official agency for current requirements.

03 / GUIDES TO HELP YOU LEARN

Understand crabs and shellfish

Crabbing, shrimping, crawfishing and oyster collecting involve different animals, equipment and places. These guides introduce the whole activity, including the access, current-rule and handling questions before collecting.

Choose the animal, water and method together. A line-and-net lesson, a trap check, a cast-net set and oyster gathering involve different movements, equipment and ways to finish. Start with one complete activity, including retrieving the gear and deciding what happens to the catch.

Get started with blue crabbing

Blue crabbing takes place in coastal and estuarine water, where fresh water and seawater meet. A handline draws bait toward a waiting dip net; a lift net is raised to collect the catch. Traps add a later checking and retrieval job. For a first lesson, learn who works the line or net and who transfers and checks the crab before taking another turn.

Recreational shrimping: understand the animal and the activity

Shrimping can involve a cast net, thrown out and retrieved, or a trawl, towed through the water. A trawl adds boat operation and towing; it is a different undertaking from learning a net throw. One complete cast-net set includes retrieval, sorting shrimp from other animals caught, and getting the net and catch ready before the next set.

Read the guide

Get to know recreational crawfishing

Crawfishing is a freshwater activity. With baited traps, the work includes retrieving the gear, opening it, identifying and sorting the catch, then resetting or packing the trap. A managed production pond and public wetland have different access arrangements. Include any later gear check and the route back when choosing the place and method.

Read the guide

Get to know oysters and Louisiana harvest areas

Oysters stay attached to surfaces in coastal water, so gathering them starts with the precise grounds or lease rather than chasing a moving catch. Fishery requirements, collection permission and shellfish-health classifications answer different questions. Seeing a reef or clear water does not establish those answers. An observation outing is a separate way to learn the habitat without collecting oysters.

Read the guide

Before putting gear out, match the named place, date and method to permission, applicable requirements and the handling plan. Arrange who retrieves each item, sorts the catch and takes any lawful catch to its next suitable storage. The linked full lessons explain the activity-specific steps; the official links support the current-rule checks.

04 / GUIDES TO HELP YOU LEARN

Get to know the habitat

Learn what marshes, swamps, barrier islands and floating Sargassum seaweed provide for animals. Practice noticing birds and waterside mammals, and learn how equipment can carry unwanted plants or animals between waters.

05 / GUIDES TO HELP YOU LEARN

Choose a water outing

Compare walks, paddling and boat visits, or learn about beach advisories, navigation markers and Lake Pontchartrain. Each guide explains a different part of choosing the activity, understanding the setting and arranging the return.

TAKE THE LEARNING OUTSIDE

Choose how you want to spend time by the water.

A wildlife visit can be a walk with places to pause, a paddle with instruction or a boat ride with viewing positions. Choose the activity and the actual site before planning around one animal. A useful outing has things to notice even if the hoped-for sighting never happens.

For watching, think through the approach, room to observe without disturbing animals and the return. If you want to fish or collect crabs, shrimp, crawfish or oysters, use that activity’s guide for equipment, access, current requirements and handling. Seeing an animal and collecting it are different activities.
