Exploring Sea Animals

Starfish are shaped like stars and when starfish are old they stop moving.

Puffer fish puff up when there is danger and they become really sharp.

Orca’s are black and white but they are not friendly.

Sea horse have a head shaped like a horse head and there tail is a spiral.

Animals in the sea eat seaweed but not all of them eat seaweed.

 

Marine animals have diverse life cycles depending on their species and ecological niche. Here are some common life cycle patterns observed in marine animals:

Oviparous – Producing young by means of eggs which after they have laid by the parent.

Viviparous- Give birth to live young.

Ovoviviparous – Once the egg hatches, it remains inside the mother for a period of time.

Metamorphosis – Change of physical form, structure, or sub

This week for STEAM we learned about the different ocean zones. I researched and created a labelled diagram of each zone. It had to include a description of the zone’s characteristics, pictures of the animals that live in each zone and a brief description of the zone. There are 5 different zones which include: the sunlight zone (epipelagic), the twilight zone (mesopelagic), the midnight zone (bathypelagic), the abyssal zone (abyssopelagic) and the hadal zone (trenches).

 

Here is a photo of my diagram.

In week three for STEAM we researched the different life cycle patterns observed in marine animals. We found that there are four main categories. Here are some common life cycle patterns observed in marine animals:

Oviparous – Producing young by means of eggs which are hatched after they have been laid by the parent.

Viviparous– Give birth to live young.

Ovoviviparous – Once the egg hatches, it remains inside the mother for a period of time

Metamorphosis – Change of physical form, structure, or substance

 

Here are some sea animals that lay eggs and don’t lay egg’s. I completed this chart to show the different animals and their life cycle patterns.

 

In week four we have learnt about the life cycle of a Sea Turtle. We had to cut and match the pictures to the correct part of the cycle.

 

This is the lifecycle of a turtle .

I made a Sea Turtle fact file this week in STEAM. I chose to find out about and research the Hawksbill Turtle. I found out lots of information about the turtle and put it in a fact file. I drew a picture of the turtle. I added some fun facts to my fact file.

 

 

These are some fun facts about hawksbill turtle’s.

This week in STEAM we compared the difference between the Sea Turtle and a Shark or a Whale.  We used a compare and contrast chart to write down all the things that we found out that were the same and the things that were different. 

I chose killer whale / orca.

These are similarities between killer whales/ orcas and turtles, here is my compare and contrast chart.
