Ocean Vocabulary Worksheets
Here is a collection of worksheets to help learners build ocean vocabulary. There are picture and word matching exercises, as well as word search puzzles and a crossword to choose from.
The first page above is an easy, fun activity for sea vocabulary. For words that students don’t know, you can give them clues. Say or write the word on the board and then describe it. For example: Stingray, it is an animal, it is black, it looks like a bat, it has a long thin tail, etc. For Island, you could say it is a piece of land, it has water all around it, and there is a palm tree on it. Use the language that is best for your class’s level of English.
The correct answers are as follows: Dolphin, Diver, Sailboat, Stingray, Island, Clownfish, Turtle, Seaweed, Lighthouse, Wave, Message in a bottle, Sea Lion, Seashell, Mermaid, Anchor, and Sunset.
Ocean vocabulary matching worksheet 2
This second handout has silhouettes of ocean objects for students to match. The answers are –
Treasure Chest – Lantern – Telescope – Anchor
Lobster – Oar – Pirate Flag – Octopus
Snorkel – Mask – Shell – Ship
Crab – Map – Boat – Narwhal
Ocean Life Matching Worksheet
Here is a matching activity with things that live in the sea.
The answers from left to right are: Coral, Manta Ray, Crab, Seal, Starfish, Turtle, Blowfish, Whale, Lobster, Octopus, Jellyfish, Seahorse, Eel, Prawn/Shrimp, Shark, and Squid.
Once your students have completed this exercise, see if they can describe each creature accurately. You can also ask further questions about things such as what they eat, where they can be found, which ones are delicious, and so on.
Another idea is to get learners to rank the ocean creatures from smallest to biggest.
Ocean Word Search Puzzles
Next, we have a couple of ocean word search puzzles, which are always popular vocabulary activities. The first sheet on the left is quite easy and contains the names of sea creatures. The word search on the right is much harder and contains 19 ocean-related words.
Note that answers in the puzzles can be found horizontally, vertically, and diagonally.
Ocean Crossword
Finally, there is an ocean crossword that features animals only. The crossword uses picture clues, which makes it quite interesting for English learners. If ESL students are not familiar with these words, you can let them use a multilingual dictionary to find the answers. You can also write the answers on the board in a mixed fashion or even scramble the words as well.
The solutions for the crossword puzzle are:
- Turtle
- Conger

- Jellyfish
- Dolphin

- Snail
- Starfish
- Fish
- Squid
